Review on Hudson Hi-Fi Silicone Isolation Feet - 4 Pack, Firm Block 150lb Capacity (Non-Adhesive) - Enhance Audio Quality & Stability by Julian Rash

Probably the best purchase I've ever made from Revain. For the price, these things do exactly what they say they do. I like my music with a bit of bass. My turntable is connected to a surround receiver with a massive subwoofer. My problem was that I could never get more than a quarter volume without vibrating feedback. The turntable sits atop my sodden entertainment center next to the speakers and subwoofer. After putting them under my player, the problem was solved. I can turn the volume up as high as I want, full bass and all, and no vibration feedback. The best purchase I've ever made.
