"There was a drastic change in the soundstage. I was startled at how crisp, clear and focused it had become. Images attained a new feeling of solidity. The room's dimensions seemed to have expanded. Nothing subtle about it!" [In reference to the 3-shelf rack]

          · Marshall Nack, The Stereo Times, April 2001

"The only tweak that really worked… was popping them onto PolyCrystal amp stands. This paid immediate dividends by tightening up the entire sonic presentation and keeping the awesome bass range tighter and deeper ‘n hell. The PolyCrystals also raised the already wonderful imaging a notch further toward ultimate palpability, all the while enhancing air, transparency, and focus."

"With PolyCrystal racks you can have your cake and eat it too; they're ‘delivery systems' for substantial resonance-absorbing shelving."

"Lastly, I put 6 PC Cable Towers under some of the wires. My expectations weren't very high. I've tried products like this before and currently use some cardboard shipping tubes hand cut to size. Maybe they make a difference, I'm not sure. These PC Cable Towers, however, were icing on the cake." [In reference to Cable Towers]

"…but I strongly recommend footers… and PolyCrystal cones [Isolators] are relatively cheap and very effective."

          · Jonathan Scull, Stereophile, Fine tunes #13

"The footers [PolyCrystal Isolators] are among the best products of this sort. This guy [PolyCrystal's Bruce Bodlak] knows more about isolation control than anyone I've ever met."

          · Marshall Nack, The Stereo Times, April 2001

"PolyCrystal Isolators and cones are effective too—I've tried them and I like ‘em."

          · Barry Willis , Stereophile, CES "Y2K Report"

"Music now sounded faster and images were better focused."

          · Dennis Hartwick, "Positive Vibes" at Planet HiFi

"It was immediately apparent that the soundstage character had changed. It became HUGE... the 3-D effect going back from the speaker plane was stunningly layered and airy. The space between instruments and the air around them was more completely realized. Moreover, this spaciousness arrived in tandem with an equally remarkable enhanced instrumental richness and fullness: not overly warm and swampy with a loss of detail, but harmonically and acoustically rich, with gobs of information." [In reference to the Isolation Platforms]

          · Marshall Nack, The Stereo Times, April 2001

"The Racks made big improvements in overall clarity and freedom from the muck ‘n mire of everyday resonances."

          · J-10, Stereophile, "Recommended components", April 2000

"It was sexy and engaging—it made me feel young again." [In reference to the Isolators]

          · J-10, Stereophile, "Recommended components", April 2000

"The next thought that comes to mind is the [PolyCrystal] material's ability to drain mechanical noises and vibrations from components. I hear people talk about ‘noise' in audio systems all the time without a clear understanding of exactly what they mean. Believe me, you'll have no trouble hearing that the noise is down."

          · Marshall Nack, The Stereo Times, April 2001

"…beautifully open, clear and lovely." [In reference to Speaker Spikes]
