I started my audiophile journey in 2011 with the purchase of a Sennheiser HD 600 and a Yulong D100 headphone AMP/DAC combo. The total cost for that system was $400 all in. My feelings on the purchase were mixed to say the least, I loved the performance, but the cost also seemed silly to both... Read More »

I've owned a number of decent headphones over the course of my life as an audiophile, and I always generally have a couple of pairs on hand. Mostly for listening when my wife, Beth, has control of the television and has landed on HGTV or some insanely sick horror flick that I could care less... Read More »

It was I who killed punk rock in the Listening Room with the Record Player. Well, kill might be too strong a word, defanged it might be closer to the mark. But at least I learned something about audio, so it wasn't a total loss. The moment square poseurs like me played Black Flag's Damaged... Read More »

If you are an audiophile, and have been in the hobby for more than the last five nanoseconds, then you know McIntosh. Easily one of the stalwarts of the industry, and a company that has always paid as much attention to aesthetics as to engineering prowess and quality. That is a lot of attention, by... Read More »

Arlington Heights, IL - The music swirled about the room like wine in a sommelier's mouth. I'd first heard them in a packed Arlington Room at the Arlington Heights Historical Museum in February 2018. The frozen, yellow grass out front was thawing and inside, principals Eric Krupp and John Brunner were demonstrating their Gudebrod Audio... Read More »

The Hagerman Audio Labs Tuba Headphone Amp (image by Bob Levi) About 12 years ago I reviewed the Hagerman Trumpet, a very fine all-tube phono stage, built in Hawaii. It was impressive and musical and priced around $2000. It outperformed my Pass X Phono, a $4000 piece, and I almost bought it. When I was... Read More »

Audio cables act as passive filters, affecting the performance of a high fidelity speaker system for better or worse, depending on interactions with the room, first, the electronics, second, and personal tastes of the listener, third. As with a wine and food match at a chic bistro, the resulting interactions can be mediocre to stellar,... Read More »

I've owned a pair of Zu Audio Omens—the Dirty Weekend (DW) variety—for over five years now. Zu builds high-efficiency loudspeakers that employ 10-inch full range drivers and compression tweeters, with many of their models approaching 97dB per 1 watt input. During operation, the 10-inch drivers, which are custom-manufactured for Zu by Eminence in Kentucky, run... Read More »

The Grado Labs GH4 in place at Chez Levi (photograph by Bob Levi) The GH4 is Grado's second foray into creating headphones using Norwegian pine, upping the ante and overall headphone performance quite nicely along the way. By my count, Grado has used two types of mahogany, maple, oak wood treated by a whiskey barrel... Read More »

Let's face it, AC line power is the bedrock of every audio system. Not only is this singularly common commodity a fundamentally important component, vital for powering all gear in a system, the quality of that AC power line happens to significantly influence the performance capability of every component in each HiFi rig. The bad... Read More »

The Unbearable Joy of Thinking Outside the Box Now that GTT Audio & Video head Bill Parish and I are finally back on friendly terms (heck, he even calls me on the phone occasionally to give me a hard time, and to ask when I plan on finishing the reviews I promised to write, if... Read More »

I enjoyed hearing ATC's 40A (then $12,999) speaker four years ago; enough so I was tempted to buy them (see HERE for the review). They had a fuller range than my reference, and the sound was a bit sweeter. However, my reference ATCs employ an "SL" (super linear) driver for midrange and lower frequencies, as... Read More »

I don't suppose I'm alone in admiring those who can really work with their hands. Years ago, while serving a semester-long sentence in woodshop, I envied my pals who could cut, glue, plane, and sand mundane articles like planters and bowls into magnificent works of craftsmanship. Not being able to do any of this, I... Read More »

With a firm desire for innovation and iterative design, Schiit are a company which have taken the world of high-end personal audio by storm one product at a time. Their latest creation comes in the form of the Ragnarok 2—an integrated amplifier that improves upon the original with its modular design, heatsink components, and a... Read More »

I am sometimes ashamed of how little we know about audio, how little we understand about it. We fly to the Moon, we are getting ready to fly to Mars, we have quite good knowledge of how the universe is changing and what its structure is, we have found thousands of planets that are similar...

Phono preamplifiers come in all shapes and sizes and with varying amounts of user adjustability and convenience. The ARC Ref 3 phono preamplifier is hands down the smartest phono section I have ever had the pleasure of using and listening to. At the bottom of the intelligence pecking order are phono preamplifiers that only have... Read More »

Prologue: A Berning Desire Many years ago, I purchased a boxy little bespoke headphone amp for my Sennheiser HD600's called a MicroZOTL. Built by a mysterious mid-Atlantic, not-so-mad audio scientist by the name of David Berning, the MicroZOTL was a mighty tiny wonder. I loved it so much I had physicist / audio manufacturer Berning...

I tend to jump into things blindly, especially when it comes to this hobby. Most of the amps, headphones, and speakers that I am interested in are not sold locally. Some of the best things in this hobby are made to order, and they often times don't have a 30 day trail. Needless to say,... Read More »
