  WAY Cables Poetry X Analogue XLR interconnects   Despite having access to a pretty wide range of very enticing gear, I really try to avoid the marry go round of constantly swapping gear in and out of my reference system.

Intro - Some New Toys at Stu's It's been a while. Over two years by my reckoning. There's been a lot going on in my world, but hidden away, deep in my audio bunker, I've been doing a lot of modifying, tweaking, and after doing much careful listening, I've even picked up a few new... Read More »

In the 36 years that I have been reviewing high end audio components, I have steadfastly held the notion that when it comes to cables, most mechanical filtering usually results in deteriorated sound quality. My rationale; it is very difficult to eliminate or reduce undesired artifacts in the sound signal passing through a cable without... Read More »

When we left off (HERE), I had just contacted Rob Fritz at Audio Art Cable about possibly getting set up with a loom of cables for both my digital and analog room systems. While I didn't press Rob to go the "full loom" route, he did agree to send me a full suite of interconnect... Read More »

I've always believed in the importance of well-constructed audio cables, and my systems of the last five or so years have been built around expensive (if not completely esoteric) cables from highly regarded manufacturers. I simply believed that logically, having well-made cables of a higher pedigree would give my systems a more legitimate claim to... Read More »

We had a pair of Row K center tickets for the Dover String Quartet at Alice Tully Hall in Lincoln Center. Everyone knows that's the eleventh row, but we found ourselves settling in four rows from the stage. What happened?

Roger Skoff writes about incremental improvements and value Is there anyone out there who doesn't know that, in addition to writing these articles, I also own a cable company? (RSX Technologies, for those who don't.) Positive Feedback, and I, and every other publication that I've ever written for, have all gone to great lengths to... Read More »

I was chatting with an exhibitor at last year's tiny NY Audio Show 2022 and mentioned I found the treble in his room had too much bite. I got no argument: "I like that. That's what I hear at concerts." Hmm…his comment made me pause before I continued with the rest of my list: boomy... Read More »

This was no ordinary wire product. I gave it a Writers Choice Award in 2016. The Cerberus Speaker Cable, a new top model in the vacuum line, followed... 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 »

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 »

Last year I spent quality time with the Armónico cable from Fono Acustica. The wires left a lingering impression of intense musicality, along with a desire to audition more of their products, including the top-of-the-line Virtuoso model. Felix Avalos, the proprietor of Fono Acustica, teased me along with, "The Virtuoso is a whole different cable... Read More »
