It started with a dare. A good friend of mine has always been very respectful and complimentary of my current system. I have to give him much of the credit for getting the sound to reach the level of excellence that now exists. All our late night listening sessions and passionate if not heated discussions...

Everyone has at one time or another fallen prey to a never say never moment. My most recent gaff? Never, even in my wildest dreams, did I ever expect to write a follow-up to "Paper or Plastic? Vinyl's Final Resting Place: The Next Installment" (http://leda.positive-feedback.com/Issue38/lp_sleaves.htm). In fact, I would have bet the house that the... Read More »

For years, I've ripped CD's, or downloaded music from the Internet (legally, of course) and have always found it difficult that most people simply don't understand how to properly tag the metadata!

The loudspeaker survey that I started a year ago culminates with the Gauder Akustik Berlina RC7. (Gauder Akustik formerly known as Isophon). These are rather interesting—and clearly different than the other loudspeakers I have written about in the survey—in that their 'tear-dropped' (or perhaps winged) shaped cabinet is composed of stacked 'layers' of ribs made...

I became interested in the Upower after reading about it... Read More »

Read the complete review HERE "In the absence of visual cues, auditory cues have to be that much better." J. Gordon Holt After 10 weeks of consistent use of the Zesto Audio BIA 120 Class A Amplifier, I find its performance continues to be unmatched by most amplifiers, as I did in my original review. In one parameter,... Read More »

I first became aware of the audiophile forums about ten years ago; at the time, I was working on site at Delta Air Lines in their Corporate Communications department. As a contractor representing R.R. Donnelley, I was required to spend long days there, essentially at their total beck and call. Because of the seriously complicated... Read More »

I upgraded to JRiver Media Center 19 about four months ago (thanks Jim), and while I haven't had the opportunity to check out its performance with Mac equipment, I still firmly believe that JRiver sets the gold standard for PC-based music playback. Media Center 19's performance is miles beyond their iterations from just a couple... Read More »

Positive Feedback readers with an analog attitude will likely have taken special note of Myles B. Astor's extensive evaluations of both the Audio Desk Systeme and the Klaudio ultrasonic record cleaning machines. While the two machines have significant differences in how the ultrasonic technology is utilized, they share both the basic "toaster" form factor, and—how'd you guess?—the same price. $4000. ...
