Music Interface Technologies (MIT) products have had a place in my system on and off over the last twenty years. From the MI-850 Tri-wire designed for my long lost and loved Avalon Radian speakers to the subject of this review, the ACC169 Speaker Interface and the Oracle MA-X SHD XLR Interconnects. In that time I... Read More »

Wilson Audio Alexx Loudspeakers Every once in awhile (though frankly, more frequently than I care for), I chuckle, nay, swing my arms and hands in protest at the uninformed nonsense I hear on otherwise fine and decent radio shows like Leo Laporte and his part time sidekick Scott Wilkinson of AVSforums, a highly respected audio...

Acoustical Systems' tonearm Aquilar, as well as the top-of-the-range model Axiom, are characterized by the UNI-DIN geometry newly developed by Dietrich Brakemeier. The analogue specialists from Bavaria have not yet invented a new generator principle, but with The Palladian Cartridge they thoroughly demonstrate how far one can get sonically with the ingenious combination of already...

Empiricism vs. Theory What was my biggest discovery last year? Bass traps. I installed them in the left and right front corners behind the speakers, as recommended. Having done my homework, I knew what to expect: low-end response would be smoother and tighter, clarity would increase, and some dampening would occur. The treble also would... Read More »

When I first requested an opportunity to write about the next new First Watt amplifier, I was candid with Nelson Pass that it was possible my Von Schweikert Audio VR-35 Deluxe loudspeakers and passive Bent Audio AVC-1 linestage might not be a good match for any First Watt amplifier. Several months later, I received a note... Read More »

I really couldn't resist the splendid speaker and interconnect cables from Göbel Audio. To be on the safe side I therefore listened only briefly to the power cables, but exchanged them before I got used to it. However, the most recent digital cables I cannot hide from you—and really don't want to—despite this being a... Read More »

Merrill Wettasinghe with his Merrill Audio Christine Preamplifier at Nack Labs When you think about it, the room is arguably your most important component. I am well aware of the sound of mine, a 12' W x 8' H x 32' L living room. I had a choice: setup on the long wall for soundstage width,... Read More »

Speakers—out of all the components in the audio chain— have seen the biggest advancements in performance over the last couple of years. Cabinet design. Driver design. Enclosure and driver materials. Computerized speaker design and crossover modelling. In house machining and construction. These factors and a few more have gone a long way to elevating high-end... Read More »

Positive Feedback has reviewed a number of products from Sophia Electric. Way back in Issue 8 of audioMusings hardware reviews, I was fortunate enough to review their "Baby" tube amplifier. Recently, I reviewed their gorgeous Coke Bottle KT-88 ST tubes. The subject of this review is the Sophia Electric Magik Box. If any component in... Read More »

The Esoteric K-01X SACD/CD player that I recently reviewed was an amazing performer. It was my first experience with an Esoteric product and I found it to be extremely impressive—one of the most impressive components that I spent time with in 2016. In support of my extensive series on integrated amplifiers, I was also given... Read More »

I'm no stranger to reviewing Raven Audio gear having previously reviewed a pair of the Raven Audio Silhouette Reference amplifiers and Silhouette Reference preamplifier, and the Shadow Reference stereo amplifier for PF. All Raven gear shares something in common, and that is the ability to reproduce music in such a way that it never fails to... Read More »

The Super Audio CD Player, Ayon Audio  CD-35 turned out to be significantly different from typical products of this type, both in terms of technical aspects, the sound quality and price/performance ratio. We believe that this is the player that changes—in a micro-world, but still—rules of the game, because it aspires to the level previously... Read More »

Zesto's audio designer and chief engineer, George Counnas, reminds me of the late great William Z. Johnson of ARC fame. Johnson just had to think about what he wanted to build and then he built it. Easy! George Counnas just thought about the ultimate phonostage with flexibility never before seen in audiophile design history and... Read More »

The Unison Research Unico DM amplifier (image courtesy of Unison Research) "There is no end. There is no beginning. There is only the infinite passion of life." - Federico Fellini You've got to hand it to the Italians: the paintings, the operas, the suits, the fast cars, the food, the wine. Theirs is a cultural aesthetic... Read More »

Devialet has now introduced their latest generation of product called the Devialet Expert Pro series that will replace the Expert series.... Read More »

The humble phono stage is the unsung hero in most analog systems, yet many hobbyists overlook its importance and often allow it to become a bottleneck. This is especially true for those folks who operate in the affordable realm of vinyl playback, and are concerned with getting the most from their audio dollars. This topic... Read More »

The Esoteric K-01X SACD/CD Player It has been an interesting couple of years while ramping up on my knowledge and experience with computer audio and the latest from all things digital. For those marketing folks out there, the traditional definitions for innovators (2.5%), early adopters (13.5%), early majority (34%), late majority (34%), and laggards (16%)... Read More »

Since the modification to my solid-state Reference Marantz integrated amplifier more than a few years ago, my tube amplifiers have been gathering dust. My modified PM15S1 has been getting the lion's share of the musical stage at my house. But a recent upgrade of my Margules U280SC to 25th Anniversary Edition has changed all that.... Read More »
