My listening room is of irregular shape, being 12.5' wide x 13.5' long in the right section, and 18' long in the left (equipment) section, with a ceiling height of 8'. It is cambered left and right, with no perpendicular edge on the sidewalls to ceiling transition. Construction was done with 2" x 6" studs, wall-within-a-wall on the left and right sides (media storage in a room to the left, equipment storage in a room to the right). The room is on the second floor, directly over the garage—no competing sounds! The neighborhood is quiet, being located on top of a hill some 500 feet above the valley below, the listening room faces south, away from the main access road.

Power to components in the listening room is fully dedicated. 10 gauge Romex was pulled directly from the panel, all from the same pole to avoid ground loops. Four 20 amp runs were done, and Hubble hospital-grade plugs were installed. All lights and peripheral components are on separate circuits. Circuits have been tested for proper ground and polarity.

The home theater system is housed in our great room. The dimensions are 18' wide by 24' long, with a peaked and vaulted ceiling that's 16' high at the center of the lengthwise room line. The fireplace forces a "shift left" of the High Definition TV and the L/C/R playback, a necessary compromise that skews the sound somewhat, but still allows for a satisfying home theater/surround sound experience.

Our listening room is about 18' long x 14' wide and has 9' coved ceilings. All walls are lathe and plaster with suspended wood floors (construction is 1928 Spanish) which have been reinforced directly under the speakers with concrete pillars. While this is our living room, it has become dedicated more to audio than to casual conversation. As such we have employed a fair amount of room treatments (EchoBuster, Marigo, and Shakti products), as well as two dedicated AC lines. Speakers and equipment have been painstakingly measured and set up to offer the best presentation possible. Our musical tastes are pretty much all over the map, but we do prefer music that is more slanted and "alternative" to the accepted norm—regardless of the genre. I should add that in my room, the Reimer Tetons are pretty much flat to 25Hz.

When we listen to music, Carol and I prefer a full-range sound that places the performers out into the room. We like a more "in-your-face" sound as opposed one where the soundstage sits well behind the speakers. Additionally, we like our music with a bit more "syrup" than most so our current system is slanted towards the richer and warmer side of things. Another thing we do like is detail and imaging. Yes, a well-defined soundfield that offers a well-lit stage is what we are after—though one that stresses musicality over sterile neutrality. Not lush mind you, but a bit perhaps a touch darker than most.

Special Mention: Sony's 34-inch, 16x9 aspect ratio, Model 910 HDTV—that all too often makes tearing myself away from Law and Order and its spin offs or a good movie and turning on the audio system, extremely difficult!)

Room: Although my new city listening room is similar in size to my long time Bronx digs, (18 x 12 x 8 vs the old 19 x 13 x 8 ft.), the speakers now fire along the long instead of short wall resulting in a significantly different presentation. Instead of the verrrryyy…. wide soundstage and musically rich sound of yesteryear, my new listening room remains musical but significantly less colored and more transparent with a narrower but deeper soundstage. And I'm not finished experimenting with and tuning the room's acoustics, so I expect even better things out of the frequency extremes (not to mention that the new VPI HRX should shore up other areas!).

Software: My musical library currently numbers approximately 8000 LPs (considerably thinned out before last summer's move) and 700 SACDs, DVDs and CDs. Musically this breaks down into roughly 85% classical (Consisting of the original Mercury, RCA, Lyrita, Harmonia Mundi, EMI, Decca/London, Argo and many other wonderful labels), 5% jazz, 5% rock and 5% assorted (world music, soundtracks, country, etc.).

Listening habits: In a nutshell, the system must first and foremost, sound musical, not mechanical. The system should in those oh-so-rare rare, but precious moments, transcend the mechanical and recreate the illusion of the real event. At the same time, this musicality shouldn't result from gross colorations or distortions, such as that displayed by bad single-ended amplifier designs.

Though I can appreciate the diversity of approaches and paths to attaining audio nirvana, I absolutely loathe upper midrange aberrations. Specifically, that upper midrange brightness (note that what many think is a rising top end is in actuality traceable to problems in the upper midrange area as defined by HP). This upper midrange brightness results in part from non-linearity, not the frequency domain distortions (for more on this, see the early seminal papers on capacitor design by Curl and Marsh.) Another reason for this upper midrange distortion(s), although far less common in current equipment, is the presence of ferromagnetic leads/material in the signal path.

Other than that, I'm highly partial to systems that create a realistic soundstage (in other words, a quartet sounds like a quartet and not a symphony or vice versa) and imaging (I've never heard an orchestra sound, even in the worst musical venue, err Avery Fisher Hall, sound like amorphous, ill-defined blobs of sound), a wide frequency response, and musically consonant, not over-etched, low-level resolution.

That said, I'm probably a bit more tolerant than some to a slight loss of macrodynamics (the type one might have to sacrifice with the best electrostatic, though not anemic like early Quad speakers, that despite all their attributes, just couldn't overcome one of their most significant weaknesses). Maybe I'd be less tolerant of this flaw if large symphonic works were a listening staple in the Astor musical repertoire. Or possibly it's because I place more value on microdynamics (damn those tradeoffs!), or what musicians term dynamic shadings. Dynamics shading, along with the unspoken element, musical silence, are probably two of the most important components of music that receive little or no attention from many audiophiles.

I have a LONG, rectangular listening room—32' long x 12' wide x 8' high—ideally suited for the rule of thirds: speakers are positioned one third into the room and about 24" from the sidewalls, facing straight ahead, the listener sits another third into the room. Two dedicated 15-amp lines power the system.

After years of trial and error, I've pared down room treatment to: Harmonix RFA 78i Room Tuning Discs, 4" Sonex panels at the first reflection points on the sidewalls, an Echo Buster Bass Buster, three Argent Room Lenses and a quartet of Acoustic System Resonators. The speaker placement in tandem with these room treatments gives me an amazing amount of layered depth and good image height, but a somewhat compromised width.

Most often you'll hear Baroque music in our home, followed by other classical repertoire and a bit of jazz. The system is voiced for harmonic richness and musical involvement over accuracy and detail.

My secret weapon is my wife, Lynn, who provides invaluable musical insight. With decades of training as an oboist, and now serving as VP of a community orchestra, she knows what sounds natural and what doesn't. Many are the times she's pulled me back from the brink after a multi-day audio binge.

My main system is located on the short wall of a 19' x 11.5' family room. In 2006, I had Vinnie Rossi of Red Wine Audio modify my Squeezebox 2 and it is now my main digital source. Also in 2006, I saw my first serious action with a soldering iron, as I took on the challenge to rebuild a 1959 Eico HF-86 with the help of Jim McShane (http://pages.prodigy.net/jimmcshane/) and Jay Waxler (Harmony Audio of Bloomington, Indiana). The Eico's body is a bit ugly, but it sounds terrific driving my Omega Superhemps!

I am truly excited to now own a pair of Larry Moore 300B amps. Quite unfortunately, they are currently being reworked by yours truly due to a serious mishap with a certain shipping company. They will recover from their injuries soon and be back on the playing field in time for next season. My limited, yet fulfilling entry into DIY really has piqued my interest and I am really looking forward to building an amp from ground up at some point. When I do, you can be sure I will document my journey.

The little multi-channel system that resides in my office has really opened my eyes to the potential of the format, whether it is SACD, DVD-A, or some other high quality form. My three-year experiment with music servers, has shown me the true potential of that method of playback and I believe strongly that most audiophiles will eventually use some form of computer-driven digital playback media in the not-too-distant future.

Listening to music is really my first audio love and I enjoy the majority of musical genres, especially bluegrass, American roots, western swing, jazz, classical, and folk music. However, good old rock and roll is still my first love. I appreciate your support as I endeavor to write entertaining prose about my experiences with audio. Thanks and rock on!

Walls are 5 layers thick, floor is lam beams with double tongue and groove epoxy laminate plus 1" of concrete and then finished with Multicolor Indian Slate. Special wire trays for all cables are under the pier and beam and accessible from panels behind my equipment when swaps are necessary.

I have two utility company electrical transformers feeding my home. I am wired for 3 phase 240 and have 14 dedicated circuits fed from a 750 amp trans-socket commercial meter for the audio system alone. Also have provision for European equipment via three dedicated 240 volt runs at front and amp positions in the room.

My finished room passes for a traditional (untreated) living room with lightly textured, painted sheetrock walls. Happily, it retains the appearance of a traditional living room rather than an "alter to hi fi" design.

Although my degree's in fine art, the only work I could find after graduation was neither creative nor rewarding. A high end audio store that I visited almost every week seemed like paradise to me. I loved listening to music on their tube electronics and learning about each system they had set up. One day while speaking with the owner I remarked that working there would be a dream job, and to my surprise they offered me a sales position. That high end audio store and the three that followed exposed me to every major product in high end audio. The last store was mine, supported by an investment group with me controlling buying and day to day operation.

Discussion came up from a major rep firm about me representing them in a five state area. I accepted the job calling on high end audio stores, offering technical support for Infinity Systems, ESS, Sennheiser, MB of Germany, Ampex, JBL Commercial, Crown International and Yamaha. I found relief during the long hours on the road experimenting with my camera. I captured images of people, the stores I visited and interesting scenery I discovered along the way.

When calling on a high end audio store in Dallas, a fellow graduate from my university recognized me. He was the creative director for a local advertising agency. After much discussion over the next few weeks, I was offered a position as their in house photographer. This agency and photography received all my devotion for two years, and suddenly my work became recognized. The owner of the best photo studio in Dallas, offered me a position shooting for the Neiman Marcus Christmas Book and Dr. Pepper catalogues.

Soon my freelance work was blooming, including into a multi year contract with Southland Corp., providing people, real estate and annual report images. I spent 11 years doing the in flight magazine for Southwest Airlines, and well as advertising photography for Interstate Battery, Exxon/Mobil, Quest Medical, Bank of America, Redman Industries, GAP, Raytheon, Fidelity Investments and Texas Instruments.

I never lost my passion for audio, soliciting assignments from audio manufacturers at CES . To date, my advertising images have appeared in print and magazines representing Atma-Sphere, Audioquest, Purist Audio, PSE, Versa Dynamics, Sound-Lab, Counterpoint, Aria Audio, Sound-Lab, Essence, Musical Fidelity, Aesthetix, Benz, Basis, Graham, Sound Anchor, McCormack and Maxxhorn. 

My wife and I have been together for thirty five years and have one son, John who is the love of my life. I host a group of music loving friends that meet at my home every Tuesday night to spin LPs and CDs. I've hosted this without fail, for 29 years and I have learned much from visitors that I share music with. Most in my group are audiophiles and all are music lovers. Some are solid state guys, some are tube guys. This leads to diversity in equipment testing and keeps me experimenting with new ideas.

OK there it is and not too soon. I offer a thousand apologies for not updating this sooner. I have lived with the excellent Margules tube amp for over three years and it has never appeared in these pages other than mentioning it in reviews. It is my best amp and my workhorse. Shame on me! It will soon be replaced by the latest version Margules has to offer. Other gear have come and gone sadly without much fanfare. In the past several years I have vowed to pare down my system to a couple of integrated amplifiers and leave it at that. Ever since my review of the excellent Tonian Labs TL-D1 speakers, my attitude towards gear and recordings in general has changed significantly. I'm getting there. But boy does this hardware suck you in like the preverbal black hole! Therefore it would be real hard for me to sit here and go on and on about how much I love music. We are gear heads! We love gear! We review gear! OK we love music too.

A Leben CS600 vacuum tube power amplifier is used with a matching Leben RS28CX full function vacuum tube preamplifier (i.e. with phono stage). The RS28CX preamplifier is treated internally with Acoustic Revive QR-8 Quartz Resonators, an Acoustic Revive RGC-24 Ground Conditioner is attached to its grounding connection, and Acoustic Revive SIP-8F RCA Input Shorting Plugs topped with Acoustic Revive QR-8 Quartz Resonators are inserted into unused RCA connections.

SOURCE
Music maker analog sources are an Indian Rosewood & Spruce Larrivee parlor guitar, Adirondack Spruce & Brazilian Rosewood Gibson Advanced Jumbo guitar, and an Eastman Uptown AR910CE arch top jazz guitar & Henrikson Jazz Amp & Analysis Plus Yellow Flex Oval guitar cable. These sources are victimized daily at the hands of my modest musical skills, and help to remind me of what's important musically when I get too far afield in my HiFi daydreams. While I search for a new turntable my friend Pete Riggle has been kind enough to let me use a vintage Thorens 124 turntable equipped with a Rega RB300 tonearm, Pete Riggle Audio VTAF & counterweight, and Denon 103 MC cartridge from his vintage collection—thanks Pete! When using the Denon 103 I also use an Auditorium 23 step-up transformer designed specifically for the Denon 103 MC cartridge to feed the Leben RS28CX's phono stage. On the digital front I use an Apple MacBook with iTunes and an Airport Express (still looking for the 'perfect' DAC for this front end), and a Sony PlayStation 1 SCPH-1001 with Furutech G-320Ag-18F8 power cord for Redbook digital duties.

CABLES
I primarily use Audio Tekne ARSP-500 speaker cables and ARC-500 interconnects in my main system; but I also use Auditorium 23 speaker cable; various SilverFi interconnects, digital interfaces & speaker cables; White Lightning Moonshine DIY interconnects & speaker cables; and Nirvana interconnects & speaker cables; for matching purposes during reviewing. I use a Furutech G-320Ag-18F8 power cord on my Sony PS-1 SCPH-1001, and the Furutech G-320Ag-18 IEC power cord in various applications. Acoustic Revive Power Max II Power Cables are used on the Leben amplifier and preamplifier.

I use a McKinnon Bellevue Symphony walnut media cabinet to house my electronics, which was lovingly hand-made by the nice ladies of McKinnon Furniture in Seattle, Washington. The top of the cabinet serves me as an amplifier and turntable stand as well.

My primary listening room is a 20' L x 17' W x 17' H living room in a rather small and modest nuevo bungalow. Room construction consists of sheet rock walls & cathedral ceiling, and a concrete slab floor (carpeted). The living room opens to a combination kitchen/dining room of roughly similar size on the rear wall, and is also open to an entryway on the right side wall. The local environment is one of a shrub-steppe—the Snake-Columbia shrub-steppe—which is an arid low-rainfall area located along the Columbia River in eastern Washington State. The electrical grid here provides clean and plentifully cheap power, much to the delight of local HiFi buffs.

I think it would be a misnomer to call my smallish 11' L x 11' W x 9' H video room a home theatre room, as it's really just a cozy little place for me to hole up while watching a good movie or television show over a nice little 2-channel system. The construction is sheet rock walls, with a flat ceiling, and a concrete slab floor (carpeted). The room does double duty for reviewing equipment to see how well said equipment can perform in a smaller room context, which is becoming a more important consideration for many people in these days of globalization and rising prices of living spaces.

Travel System

My travel system is an iPhone used with Shure SE530PTH headphones. I like to travel light to make my life easy on the road. With an iPhone I can make telephone calls, text message, surf the web, send and receive emails, get driving directions, and check the weather. Oh yeah, I can also listen to music and watch movies if I'm on a long coast-to-coast flight. The Shure sound isolating in-ear headphones shield me from the baby crying two seats back, are comfy, and provide a rich and expressive window into the music (or movies) that is quite captivating. This is a great way to go for road warriors who want to travel extra-light.

Listening Biases

I thought a thumbnail sketch of my listening biases might be helpful for interpreting and decoding my reviews. Just to alert you, my perspective is somewhat one of a minority alternate opinion in the HiFi community. My hierarchy of importance is aligned more closely to how well a HiFi rig plays the musical content of recordings, rather than how it 'sounds' in the more traditional audiophile 'sonic' sense.

To this end I look for timbral realism at the band level (the band's signature 'sound') and at the individual instrument level (the unique 'voices' of instruments). I want them to sound recognizably like themselves in tone and texture, so that their full tone color can develop, which I think helps lend a feeling of beauty and expressiveness to the music. I like the melody (the tune you 'whistle while you work'), harmony (treble & bass accompaniments to the melody) and rhythm (the steady beat that determines the tempo) to have a life-like flow and connectedness in how the musicians interact—just like in real life. I want dynamics (variations in loudness) to evoke that which I hear in life for an emotional connection to the melody and rhythm. Finally, I want tempo portrayed so that both the mood and speed of the music are conveyed through it, just like with music in real life.

I consider the sonic performance of a HiFi rig on the non-musical artifacts of the recording process to be of value, but of less importance to me than the performance on the musical content of recordings (as above). So things like transparency (being able to 'see' into the recording), soundstage (the three dimensions of the recorded space in width, height and depth), soundspace (the acoustic 'space' of the soundstage), and imaging (the feeling of solidity and localization of instruments & musicians on the soundstage) has some importance to me, but they are not my primary focus. The musical content is.

So I like my cake (the musical content of recordings) with a little frosting (the non-musical artifacts of recordings) for a balanced taste treat. Too much frosting and not enough cake put me off. So that's me, and you might be different, but at least now you know how.

MIKE PESHKIN'S SYSTEM

LOUDSPEAKERS
I use Infinity P-FRs. I was impressed by their looks, and further impressed by a number of reviews, but when I finally decided to buy a new pair of speakers, the way the Infinities made guitar music sound convinced me they would be mine. When I met the head of sales for MIT Cables at that time, she told me about the development of the speakers (she had worked for Infinity before joining MIT), and reinforced my desire to have them in my home. (Of course, it may have been that she was one of the most beautiful women I'd ever met.) The P-FRs are very efficient (96dB). The manual states they can be driven by as little as 10 watts. I have always driven them with considerably more than that, 100 watts at present

ELECTRONICS
My preamp is an Anthem Pre-1 (internally selectable, 61 or 78 dB). When I replaced the original Sovtek 5V4G in the outboard power supply with a Mullard 5AR4, a very good preamp was transformed. Putting Mullard 6922s in the input and output stages and Mullard 12AT7s (CV4024) in the phonostage made it a giant killer! Using Walker Valid Points pumped up the sound quality a few more notches. An MIT power cord feeds the power supply. The amplifiers are 100-watt Monarchy 100SE monoblocks, whose outputs have been modified by Lloyd Walker. These are warm, yet very detailed amps. The combination of the Pre-1 and the 100SEs produces a sound that I'd been reaching for since I got seduced by high fidelity sound—warm, perhaps too warm for many listeners, but not so much as to destroy great recordings or homogenize all recordings. Any equipment change I make is easily discerned. MIT power cords connect the amps to the wall socket.

SOURCE
My CD player is an Audio Alchemy CD Pro, a player with a laid back sound, but capable of showing both the details and the defects in any music played through it. The great sound of this player is enhanced—shockingly so!—by the use of Walker Valid Points. Another tweak is the use of an MIT power cord. To play LPs, I have a VPI Mk. IV turntable with a JMW10 arm, sitting on Valid Points. I use a Benz Glider cartridge, now growing hair in its ears, and a new addition, a Dynavector 20XL.

CABLES

ACCESSORIES
I live in farm country. Farmers have need for repair facilities, including welding shops, of which there are plenty. Although my turntable sits on a Target wall stand, all other equipment sits on racks designed by me and welded by a gentleman who does lots of work for the farmers in this area. Many, many techniques are used to control vibration and isolate the components—multi-layer shelving employing the use of hard woods and/or cork, foam rubber, and MDF. I experiment regularly with different combinations of materials, using spikes, Vibrapods, sorbothane, and other things under the shelving and on top of the racks. Bags of lead shot or sand are used on top of the speakers and in other places within the system. I use Monster power conditioners for the sources and the preamp, but no conditioning for the amplifiers. Other conditioners in the house are Adcom. A VPI record cleaner with both homemade and commercial solutions is used to clean LPs.

The equipment is housed in my living room. Others have tried to make me move to my unfinished basement, but I do not wish to divorce myself from my family. The room is on the small side (15.5' x 14'8" x 7'10"). My wife is a spinner/weaver and collects textiles ranging from small rugs to camel blankets, which are hung on the walls. The house is close to 100 years old, and has lathe and plaster walls. The wooden floors are covered with wall to wall carpeting, the ceiling with acoustic tiles that I painted to reduce their absorptiveness. The sound of the room is neither too lively nor dull and lifeless.

BACKUP SYSTEM
106 year old mono only system: Edison Home Phonograph cylinder player model CH16002.

The listening room allows only one possible setup arrangement. The area allows use of a 10-foot wall to backup the loudspeakers, though that end of the room is 15 feet wide with 5 feet being the entrance area. The first nine feet of the room therefore is 15 feet wide and then expands to well over 20 feet wide and 34 feet long (total). Therefore the loudspeakers "see" more than 700 square feet. Walls are old time lathe and plaster, concrete floor with Berber type carpeting. The room supports extended deep bass response and the response is electronically limited by manufacturing design to 16 Hertz, and extends fully and solidly to just below 20 Hertz in this room and is adjustable in all-important aspects including phase. They are rather svelte appearing and top off at only 42 inches tall and 11 inches wide with above average sensitivity. They are basically dipole radiators. Later models, such as the 500, 501 and so on contain one less bass driver per side while maintaining the almost unmatched (for its size) bass response and have eliminated the expensive titanium dome midrange driver, going to a more conventional cone. The Herron electronics, together and separately, come very close to being neutral. The solid-state units have no hint of common transistor edginess and the tubed units have seemingly no added bass fullness or bloom. The Cary player correctly decodes the under appreciated HDCD recordings by Reference Recordings and Dorian. I often question if the best SACDs and DVD-As surpass the better HDCDs by Reference Recordings comparing in stereo only, the HDCDs are not multichannel. Because I usually do a great deal of music reviewing, and most truly new recordings are digital, I find myself listening far more to CDs, HDCDs, SACDs and DVD-As than vinyl. I usually agree with those who believe that a great LP played on a fine-tubed system can almost magically envelope the listener with unsurpassed musical enjoyment. The very finest and in general the most recent digital efforts, are quite excellent and I could easily believe that in most measurable ways, are actually more accurately reproducing the microphones' outputs.

As time goes on, I become more convinced that to have an excellent recording and front-end components allows some moderately priced amplifiers and loudspeakers to be surprisingly satisfying. Please, make every effort to support the truly new recording efforts by companies such as RR, Dorian, Telarc, Chesky, AIX, Delos and others. Without them, improvements in source material will become scarce and the huge corporations will not be stimulated to record and release much of any significance for our musical enjoyment.

My main listening room is approximately 9' x 9' with 8' ceilings. It occupies a spare bedroom on the second floor of my rented townhouse, which is located in a quiet suburban neighborhood. Shared walls necessitated the placement of my rear-ported speakers nearest an interior wall. By coincidence, it's a load-bearing wall, allowing for unusually stable equipment placement. I can walk around while an LP is playing, leading me to believe above-average construction standards were applied.

Given the square-shaped room layout, setup by the ‘rule of thirds' is impossible. As a compromise, I selected 10' speaker cables to allow plenty of flexibility with on-the-fly speaker placement. Depending on the electronics and music, I may place the speakers closer to the rear walls or farther away, but usually toed in to some degree. (My long, rectangular living room— equipped with an overachieving Denon stereo receiver and DVD player—is also used to audition speakers when they can't be properly accommodated in the main listening room.)

Without enough room to adequately indulge my hobbies, the goal with this system is to achieve a home theater that sacrifices as little as possible in terms of my criteria for high quality audio, whether two-channel, 5.1 or 7.1 multichannel. Those criteria are mainly oodles of detail and solid imaging and sound staging, I like a forward, somewhat in-your-face presentation, but with good front-to-back imaging that closely mirrors intimate, live listening experiences. My favorite genre is small-ensemble jazz of the '60s, but I listen to an incredibly wide variety of material, from Bach to the Beastie Boys to Black Sabbath. My favorite composer is probably Mahler. I have a passion for films as well as music—thus the plasma display—and sometimes indulge in video games. So for the time being I'm using a Playstation 3 as a Blu-ray player. Even on this modest source, I can achieve a seamless surround field controlled by the Integra preamp, in which the VAC Phi amp, set to "home theater" mode and decoupled from its internal preamp, drives the front L/R speakers and the YBA five channel amp drives the center and surrounds. This way I can explore multichannel SACD and the high-resolution flavors of PCM afforded by Blu-ray.

I do not play the switch-out game too often these days with my stereo and surround sound in the living room. Both playbacks are combined in our main listening system there. We do not have separate/dedicated rooms excluding the studio. I have made acquisitions over the years whenever something grabs me so deeply I know it would sing with my components, but for the most part I have been happy with the music coming from my system for a while now. This was, of course, the result of many searches and trial and error sessions. Once we (my wifey and I) reached a point where we were constantly excited by our system I stopped shopping around all the time. We have come to love the sound of our system, and while I still listen to new stuff all the time as part of the addiction, I'm usually just exploring to see where the art is going. I also do a great deal of listening in the little office space where I write, and that gear changes often. We also do a lot of listening in the studio.

I LOVE doing "jukebox" nights at the house, where we invite friends to bring records and some drinks. We all spend the night getting loose and turning each other onto new music (or old, if we discover something grand).

My current room is a 22' x 17' family room backed by a 24' x 10' kitchen, essential making it a 22' x 27' room with plenty of bare walls, hard surfaces and vaulted ceilings that start at 10' and slope upwards to 14' 9". It's not an easy room to love.

The room also does double duty as a two channel home theater as can be clearly seen from the Toshiba 65" HDTV set back from and between the speakers. A heavy blanket tossed over the screen mitigates the effect of the very reflective screen surface during listening sessions. Rotating everything 45 degrees so that the speakers fire diagonally across the room and placing the speakers well into the room with no toe-in provides smooth tonal response and minimizes early reflections to create a well balance, believable and detailed soundstage. Echo Busters in the corners and along the ceilings minimize the horn effect and slap echo.

Still, a room this size without extensive treatment is difficult to tame and its long reverberation time adds a bit of smear and hardness to the sound and slightly diminishes image localization. And while no room is perfect, this one is less perfect than many. Rather than fight the power, I am currently working with Rives Audio to modify another room in the house as a dedicated two channel home theater/audio room. The emphasis will be on two channel audio with an electric projection screen built into the ceiling so it can easily disappear for critical listening. I expect to complete this project by July of 2007 and will provide photos and details when it is complete.

In a sound system, I listen for the sound of music. While it is possible to break what that is down into its components, harmonic structure, sound staging, dynamics, etc. ultimately it's either right or it isn't and like beauty, that can take many forms. (If it didn't how else could different sounding systems all create a believable illusion of music?) That being said one of the easiest ways to destroy that illusion is with poor tonal accuracy and exaggerated or compressed dynamics. To me, if these two elements are well executed, the illusion of instruments and voices in the room is at least possible.

While excellent sound staging is important it's hard to find a product these days that doesn't produce at least a decent soundstage if properly set up. Even the cheap no-name speakers that came as part of the package when I bought a computer recently will create an image. Perhaps that is due to their small size. Of course, they don't come close to matching the precise imaging of the Triangle Zays' but it is a soundstage nonetheless and most of the high end products I have heard in recent years do a pretty decent job in this area. And of course there are varying degrees and expressions of this phenomenon and I will be discussing this in my reviews.

Having played the drums since the age of 8, I'm particularly attuned to the sound of percussion and can easily distinguish an indistinct thump from the sound of a wool beater striking a bass drum head followed by the nearly instantaneous reaction of the outer head. The sound of a drum stick on cymbals is a dead give away as to the overall harmonic structure of a system hence my preference for tubes. And there probably isn't another acoustic instrument with the dynamic range of percussion.

Musically I enjoy most (but not all) genres. Having grown up in what I consider to be the hey day of classic rock, I will always have a soft spot for those bands (Led Zeppelin, The Who, Yes, Pink Floyd, Rush and so many more). I saw Led Zeppelin at Madison Square Garden when I was 15 and to me the movie Almost Famous captures that time better than any film yet made.

I listen to rock, blues, big-band, jazz, folk, classical, R&B, rap and more. I think Adrian Belew is a genius and in their own way, so are the Beastie Boys. (Just listen to Paul's Boutique.) You probably won't hear any references to country or opera out of me, but I can live with that. Happy listening!

My room is a 22' x 13' dedicated sound room designed by Rives Audio. The vaulted ceiling slopes from 10' to 14' 9". It has three dedicated, isolated ground 20 amp circuits feeding Hubble hospital grade outlets. The first and second sidewall reflection points are treated with absorption panels and RPG BAD Arc diffusion panels hang between them. A series of angled diffusers hang from the ceiling to further scatter reflections and the rear wall consists of angled bookcases to create a diffused surface behind the listening position. Extensive bass trapping above and to the sides of the bookcases helps tame room resonances. A 16:9, 100" diagonal Stewart Filmscreen descends out of the ceiling for watching movies, but the room's main purpose is music reproduction.

In a sound system, I look for sound that is emotionally engaging. While it is possible to break what that is down into its components, harmonic structure, sound staging, dynamics, etc. ultimately it's either right or it isn't and like beauty, that can take many forms. (If it didn't how else could different sounding systems all create a believable illusion of music?) That being said one of the easiest ways to destroy that illusion is with poor tonal accuracy and exaggerated or compressed dynamics. To me, if these two elements are well executed, the illusion of real instruments and voices in the room is at least possible. Having played the drums since the age of 8, I'm particularly attuned to the sound of percussion.

My listening room is about 20' long and 15' wide. My ceilings are cathedral style starting at about 9' tall and about 15' tall at the seating position. The Apogees are known to be amp killers but with the right combination they product music more accurately than any cone based transducer that I've listed to. When I hear traditional cone speakers I hear the driver itself as the music hits it, with ribbons they are as light as air and the music dances around them in a magnetic field.

The Scintillas place the instruments right in your face, and the vocals right down the middle. They are a bit picky with placement, needing to be about 5' from the rear walls, and about 6.5' from each other.

The Divas offer a much taller sound, and are a much more efficient design using Kapton backed foil drivers. You could run these on tube amplifiers if you prefer.

I sit about 10' from my speakers and prefer to have the effect of being in the front row of a live concert. It is generalized that you can not get any deep bass from a true dipole ribbon driver but that is not true, with the Scintillas I've negated the need for any subwoofer.

WILL WRIGHT'S SYSTEM

LOUDSPEAKERS
Extensively modified (by me) Carver Amazing dipole loudspeakers. The original four twelve inch woofers per side have been replaced with Adire Audio dual voice coil DP12s. Additional bracing and damping has been added to each panel. The original passive crossovers have been removed and replaced by White Instruments 24 bit digital Paramedic 26 XLR crossovers. All line level connections are balanced. The four twelve inch woofers are augmented with a DIY sub for each channel utilizing a fifteen inch Adire dual voice coil Tempest driver in an eighteen inch ID by three foot sealed sonotube enclosure. The subs are down firing and located in the front corners behind the Carver panels. Each stereo channel is tri-amped. Crossover points are sub to panel woofers @ 40Hz 3^rd order, panel woofers to full range ribbon @ 300Hz 3^rd order.

ELECTRONICS
Subs are powered by Adcom monoblocks @ approximately 500 watts into 4 ohms, Panel woofers are powered by Hypex plate amplifiers built into the base of the Carver panel @ 720 watts into 4 ohms, Carver full range ribbons are powered by one channel each of two Krell KSA 200S. Line level preamp is the Alchemist Tim de Paravicini Signature. The phono pre is the Sutherland PhD.

SOURCES
Analog: Goldmund Studio turntable modified to run on batteries with the T3 servo controlled tangential tracking arm and the Lyra Helikon moving coil cartridge. Digital: Esoteric DV-50 universal disk player. Still on the workbench but soon to be added is a dedicated "Home Theater Computer" built from scratch and featuring dual Xeon CPUs. It is a silent, water-cooled (no fans) design using a separate convection cooling tower. This will house acoustic measurement software, CARA speaker location software, music database software, LP digitizing software, digital crossover control software and double as a music server and home theater controller.

CABLES
Interconnects are all balanced Soundstring cables except for turntable to phono pre and phono pre to line level pre which are single ended Soundstring. Speaker cables are all DIY except for the Carver 60 inch ribbons which use Goertz flat copper. Power cords are all Soundstring.

ACCESSORIES
The turntable and universal player are sitting on Critical Mass Systems Grand Master isolation platforms atop Lovan equipment racks. The preamp and phono pre are sitting on a Halcyonics Micro 40 active isolation platform. All other equipment is on Black Diamond racing shelves and/or cones and pucks, including the speakers. Power filtration is via a Jack Bybee/John Curl Signature purifier. Acoustic treatments are primarily DIY tube traps and diffusers. Acoustic room measurements are done using a DIY computer based Liberty Instruments IMPM MLS system. Parametric EQ, level matching and delay, etc. are programmed into the digital crossovers based on the measurement results.

My listening room is in the basement and is underground to a level of about four feet. Floor is tile over concrete slab. Walls are wood paneling. The room is squarish at approximately 23 feet on a side and ceiling height is 7.5 feet. Considering the room shape it is surprisingly free of standing wave problems and I attribute this at least partially to the way dipole speakers load the room and to the fact that the subs in the front corners are crossed over at a point below the first room mode. CARA software was used to determine the panel speaker positions. They are about six feet from the side walls, seven feet apart, three feet from the wall behind them and toed in toward the listening position.

Power to components in the listening room is via five fully dedicated lines. Front end components have a dedicated 6-gauge line directly from the main panel. Amplifiers are located at the speakers and each channel's amplification is on two separate dedicated lines one utilizing 6-gauge and the other utilizing 10-gauge Romex connected to the basement sub-panel. All dedicated lines use hospital grade or better duplex outlets. All other power to the room is separate.

My listening room is 14' wide x 12' long with a ceiling height of 8'. My speakers are 8½' apart measured by their innermost point toed in slightly to get a more realistic image of an orchestral shell. Even with my speakers placed this far apart the phantom center image is solid and there is no hole in the middle. With the best source material the image is huge expanding beyond the outer boundaries of the speakers with excellent depth and height and ambiance in front of the performers filling up the rest of the room. Visitors have commented that my 2-channel stereo has the spaciousness that surround sound aims for but seldom achieves.

My system resides in a room that is 19' x 12' x 7.5' and the Rethms are 4' out from the one of the short walls and 6' apart. The long wall adjacent to the left speaker has three tall windows covered in blinds and the opposing side opens into the dining room. The listening couch is right up against the other short wall, but through experimentation I've found a spot on the edge of the couch that's almost ideal as far as sweetspots go: the Rethms just seem to 'gel' better if I'm positioned some distance away from them. There's also a wide window that's covered in blinds just above the couch, but the speakers seem far enough away from any wall boundaries to cause any serious interactions. So, not an ideal room, but I think I've made the most of it.
