The Usher R-1.5 stereo amplifier is built like a tank. Its utilitarian industrial design bears a striking resemblance to the Threshold 300 Stasis designed by audio guru Nelson Pass, which should come as no surprise. In 1972 Usher Audio's owner and head engineer Lien-Shui Tsai built the first Usher R-1.5 amplifier as a copy of... Read More »

It was around the midpoint of my Hi-end audio journey when I heard my first passive power distributor and I can still recall the shock. At this time—I'm talking decades ago—the Hi-End embraced the philosophy less is more. Virtue lay in the fewest electronic devices and the shortest signal paths. Minimalism ruled. The goal of...

Together in Bits and Pieces. First Bit. The least expensive way to get great sound out of your system is to "cheat." Don't buy new gear, buy really well recorded music. The sound your system exhibited with pedestrian recordings will now sound much better, because the source is literally better. This is no joke. Sure,... Read More »

Up and Down the Loudspeaker Evolutionary Ladder From its inception nearly 40 years ago, Von Schweikert Audio has adhered fanatically to a unifying corpus of science-driven principles first championed by company founder and former chief engineer Albert Von Schweikert, sadly no longer with us. Albert's science-centered reimagining of modern loudspeaker design utilized applied psychoacoustic observations... Read More »

Staring out from the darkened hotel room, two sculpted, burly figures stand guarding the glistening golden and onyx tinted treasures between them. Suited in matching, high gloss Macassar Ebony with piano black faceplates angled back and studded with a tweeter and two drivers, at nearly four feet tall, they can swing and punch with the...

It is a particular pleasure to introduce the latest person to join the Positive Feedback creative community. Bob Katz doesn't need much of an intro to audiophiles who follow those who are masters of mastering...and of recording, EQ, and delivering the recorded performances that we all treasure. No recordings, no audio, eh? His résumé is... Read More »

Last Sunday marked a return to Town Hall, New York City, for a concert by ECCO (the East Coast Chamber Orchestra), a group of 18 youthful, professional string players. These guys (actually, most were female and Asian) were really digging in, using the full bow when they had to and, alternately, approaching near silence in... Read More »

There are few times in my life where I have been truly speechless when it came to audio equipment. I still remember the first time it happened. I searched high and low for a pair of Anthony Gallo Reference 3.1s. I had never heard the speaker, but I had read enough to know that if... Read More »

Each Zion weighs nearly 75 pounds As I sat in my listening room with the lights dimmed, I began to take a journey. My journey started with the Red Hot Chili Peppers' Unlimited Love, and I then found myself listening to Mark Knopfler's Down the Road Wherever. After awhile I ventured onto St Vincent's MasSeduction, with a short...

In Part 1 of this review, I had a great time listening to the awesome but temporarily incomplete Gingko VCS Toolkit, and I was looking forward to receiving the Cloud22 Bases to complete the review. When the bases did arrive I was intrigued to find that Vinh Vu also sent me the new Cloud22 wool... Read More »

The brilliant late audiophile, J. Gordon Holt, once wrote that if the purchaser of a fine system was torn between buying a great pair of speakers or a great amp, one should choose a great amp and a good pair of speakers that fit your basic needs. He commented that he had heard numerous systems... Read More »

When the Monet power cables from Crystal Cable were offered for review, first thing I went online for a look-see. The photos suggested a slimmed down cable with no surplus parts, nothing more than the elemental hardware required for the task at hand. The Monet is the thinnest power cables in the new Art series... Read More »

Wow! It's been a while. If you are interested in Pure Audio Project or never heard of it, I suggest you read my older review of the Trio 15 speaker system HERE. That was written back in 2019. I loved that setup; a very open / wide soundstage with the pleasantness and tonality that open... Read More »

An audio reviewer's mandate is to seek out the new, the innovative, the cutting-edge, and to write about it, preferably while it's still new and innovative and cutting-edge. As a scribe for Positive Feedback, I've certainly done my share of chasing the newest and most revolutionary products for evaluation. But, in assembling my reference system... Read More »

In 2019 I reviewed the Paradox Pulse Signature 70 MC Phono Preamp. I was so engrossed with it that I actually bought one along with the Paradox Pulse Guard R SMR Cartridge that I also reviewed around the same time. In the subsequent two years since my purchase Terence Robinson has upgraded both pieces with... Read More »
