Bob Levi:  a moment at the LAOC AS Board Banquet. Los Angeles, CA, 2023. (Photograph and image processing by David W. Robinson) I have been listening to and testing cables and other connectivity from UIT for about a decade, and have marveled at their progress. Their Perfect Music Purifier technology has improved and propelled their... Read More »

I've been working with John Soriano of Apos Audio on a number of recent equipment reviews, and through our regular contacts, I discovered a few months ago that Apos would soon be marketing their own line of self-branded premium vacuum tubes. That news excited me to no end, especially when I learned that among the... Read More »

Quite possibly, if you were to ask my non-audiophile friends, their perception of me would be one of a guy who is on the cutting edge of technology. They walk into my home and are usually overwhelmed by all the whiz-bang gadgets adorning my listening spaces. However, the truth is I was slow coming into... Read More »

One approaches writing cable reviews with a bit of trepidation, especially about digital cables, and doubly so for those circling around the kilobuck range (as the Audience AV cables under consideration here do). After all, cheapo generic—even freebie—digital cables either work…or they don't, so you just toss 'em, right? We've all heard the bits-is-bits arguments.... Read More »

The Bag End ISUB2-18 18" Infra Self-Powered Subwoofer System sits in repose in my listening and A/V room Have you ever wondered what it would be like to use the top-notch equipment renowned musicians like Tom Petty, Chick Correa, and Prince have used to produce and/or perform their hits? Long recognized by discerning artists and... Read More »

I don't really know how to pronounce Nag-a-ok-a. Or is it Nag-a-woka? I wish I could find a video on YouTube or something from the actual company where someone says it correctly. Unfortunately, they don't really do much marketing or publicity, though I'm not sure it matters. Brochure copy can be especially unhelpful where the... Read More »

When my review for Vera-Fi Audio's Main Stream™ went live a few weeks ago, Vera-Fi mainman Mark Schifter was only able to supply me with a single device for evaluation. Which according to Mark was at that point the only alpha unit presently in the field! I was really keen to first check out its... Read More »

Dean Waters with cigar at the Pacific Audio Fest 2023: a portrait. (Photograph and image processing by David W. Robinson) I recently submitted an article reviewing the Alberto Guerra Designs (AGD) Duet monoblock amplifiers (HERE). They are in a word, wonderful. Since then, I've been reviewing the Duet's big brothers, the AGD Solo Limited Edition... Read More »

A few months ago, I was pleased to write about the KECES Audio Ebravo Streamer Transport. In that review, I noted that the Ebravo, "Elevated the sound in many subtle, but easily recognizable ways." This was all to the good, of course, and that kind of discernible difference is what makes so many of us... Read More »

For almost two decades now, my reference preamplifier was the Bryston BP-26 powered by the Bryston MPS-2 DC regulated power supply. I was perfectly happy with the performance of this combination and the vast connectivity options that it offered. When Bryston introduced its new BP-19, I was impressed by its specifications, and I have to... Read More »

Early this year, Vera-Fi Audio main-man Mark Schifter messaged me to gauge my interest in a new product line he was then representing from Thai manufacturer Puron. I'd told Mark that even though I had a pair of AudioQuest Niagara Low Z, AC power conditioning units in place at the new home in South Carolina,... Read More »

Back in February's Issue 132 (HERE) I wrote about the remarkable improvement in my system from replacing a couple pricey audiophile fuses with first one, and then two Swiss Digital Fuse Boxes. At that time there remained a couple of unresolved issues—first was the impending arrival of a rhodium-plated tellurium copper "Super-Duper-Sluggo" (the actual metal... Read More »

It's been a little over eight years since I last reviewed an amplifier by Southern California's ampsandsound (HERE). In the intervening years, Justin Weber has taken his little, almost hobbyist endeavor into the world of being a serious full-fledged business manufacturing extremely high quality boutique products. His lineup currently includes six amplifiers designed for driving... Read More »

Over the last two years, I have been on a determined mission to find a standalone phono stage for my system. I have been experimenting with both solid state and tube phono stages at several different price points. I have posted a few reviews, but not for everything that has entered my listening room. The...

Fifteen or more years ago I purchased a John Curl/Jack Bybee Signature Pro power conditioner, and still use it to this day. The Signature Pro used two power cords, each one connected to a bank of four outlets, one bank labeled Digital and the other Analog. Each bank utilized three Bybee Quantum Purifiers. You may...

Of all the elements that make up a high-end audio system, few are embroiled in the kind of controversy that surrounds cables. By and large, audiophiles seem to align with one of three primary belief systems when it comes to the impact of cabling on a system's sonic signature: those who profess that wire, generally...

I wasn't a regular cyclist, and pedaling my heavy fat-tired steel Trek mountain bike on surface streets for... Read More »

As I stated in my original review, the primary function of Vera-Fi Audio's Swiss Digital Fuse Box (SDFB) is to remove and replace the weakest link that existed in the device it's connected to. Which in my case was the main AC line fuse in my PrimaLuna EVO 300 tube integrated amplifier's power supply. Other... Read More »

Dean Waters: portrait with a cigar. SeaTac, WA, Pacific Audio Fest, 2023 For the last few months, I've been listening to and delighting in a pair of AGD Duet monoblock amplifiers. These are the newest addition to the AGD product line, and are rated for a very solid 150W @ 8 Ohms (300W @ 4... Read More »
