As I began listening to the Gingko ARCHs the many audio tweaks I've tried over the years ran through my mind. The more I thought about it virtually every system I've heard, no matter price or size, included some sort of accessory I would—at least loosely—label as a tweak, an accessory that can improve the...

Having covered audio shows for many decades now, I have learned to take it with a pinch of salt when I hear exhibitors bandy about words like "revolutionary", "game changer", and "new generation" in trying to get you to focus on their products. However, what was different as I started my coverage of TAVES in... Read More »

Back in November I published a review of the 33 Rackit Modular Record Storage Unit, a replacement for the original Per Madsen LP racks. Afterward, I was contacted by Ryan Tinsel who informed me that he also was making a replacement for the Madsen racks. Per Madsen in San Francisco made a modular storage system... Read More »

Exordium I've been a lover of music and audio for as long as I can remember. I didn't really recognize myself as an "audiophile;" but from my first 45 rpm box player in '63, to an all-in-one Sears stereo, followed by a succession of Pioneers, Harman-Kardons, Yamahas, and Kenwoods; I loved gear even then. I... Read More »

The game-changing Critical Mass Systems Center Stage footers, one 25mm, and one 20mm, tall I've been using and experimenting with footers since their very genesis back in the summer of 1983, which saw the introduction of both the Sorbothane™ footed Mission Isoplat and Steve McCormack's machined aluminum ModSquad TipToes, but the Critical Mass Systems Center...

F1 Fractal™ Interconnect by Townshend Audio On the heels of the ridiculously superb (passive) Allegri+ preamplifier (HERE), with its secret sauce…fractal wire…comes the introduction to America of Townshend F1 Fractal Interconnects. (There are speaker cables also, but I did not have them for review.) The interconnects are extremely exotic looking and terminated in excellent shielded... Read More »

The van den Hul Extender in place on top of the Evolution Acoustics MM2 Loudspeaker From time to time I've roiled the tempestuous waters of high-end audio…rough enough already, without additional help from me…with favorable observations about my experiences with various system-enhancing components. Lord knows, I've patiently endured the shouting so-called "objectivists," who assert that... Read More »

For many years, Per Madsen in San Francisco made elegantly designed modular record racks which were prized by record collectors and audiophiles. With oak LP modules as well as modules for CDs and cassettes, many thousands of his Rackit modules were sold over the years. But then, in 2008, Mr. Madsen decided to retire and... Read More »

This is Part 4 of John Marks six-part series on digitizing LPs. This series is re-published from John's blog site, The Tannhauser Gate. In this set, he is providing his readers and ours with a solid and reasonably-priced way to archive their precious vinyl to digital format.  I commend John's care and attention to detail. Read...

The GamuT Lobster Chair in the sweet spot at the PF listening room in River City. "And now," said Monty Python, "for something completely different!" When planning, setting up, or upgrading their listening rooms, audio folks don't usually spend too much time considering furniture. After all, loudspeakers. Electronics. Turntables. DSD. RTR tape. Racks. Cables. For... Read More »

The Rogoz Audio website shows no less than 23 anti-vibration rack models and that doesn't include the latest series. Some of them are versions of the same model, a wider one or featuring more shelves, but still, it's a large number. Mr. Janusz Rogoz's company, since 2010, when it was founded, has gone a long...

It was about fifteen, sixteen odd years ago that I fell into the "vinyl" trap. Sure, growing up mom and pop had records, mostly of the classical Deutsche Gramophone variety; my ten years older brother had vastly greater selections diving into classic rock, some jazz and avant garde pop, but even he probably never made...

Acoustic Revive was founded in Japan in 1997 by Mr. Ken Ishiguro, who is the design genius behind the innovative and ultra-quality Acoustic Revive products. Like many hi-fi enthusiasts, Ken-san's interest in audio arose through his love for music as a youngster. Ken-san told me, "I was listening to the Beatles when I was fourteen... Read More »

This article, by Doug Blackburn, originally ran when Positive Feedback was in print - Vol. 6, No. 4, 1997. There is so much stuff going on here lately I'm beginning to think I could write a 1-man magazine. But that might not be as interesting as PF's Assembly of the Diverse so I'll compress my thoughts...

Jack Bybee's iQSE or internal Quantum Signal Enhancer (iQSE) differs from the AC Purifiers I wrote about last month. As you'd expect the signal from your component runs through the AC Purifiers. It is with some bother I note no signal passes through the iQSE, it neither plugs into anything nor does anything plug into... Read More »

The focus of this review is to contrast the Sonore microRendu and Signature Series linear power supply with affordable power supplies from Channel Islands Audio and iFi Audio, in a Roon-based headless environment. But before we get into that, a brief summation of the recent past: from the point when I first came in contact... Read More »

Stein Music's "The Perfect Interface" Carbon Signature Resonance Control mat in place on our EMT 948 turntable. Every now and then I receive a product whose benefits are so obvious, and whose design is so straightforward that there's no point in holding back or trying to write an extended essay. It isn't a complicated call,... Read More »

As Joe Walsh would say, I'm an ordinary, average guy. While I've got some very nice gear, the room itself has been neglected. I'm sure it has modal ringing, uneven frequency response, and sucky suck-outs. This chamber of audio horrors is stuffed with a mishmash of unmatched furniture, as well as several bottles of excellent bourbon;... Read More »
