My annual New Year's Day party turned into a raucous dance party. While my wall mounted turntable withstood the test, my cd transport (on a rack) was thrown off by the shaking house (raised frame construction.) Short of wall mounting the transport, what sort of footers should I try? I was thinking about Herbie's Tenderfeet, but they are probably more tuned to micro rather than macro vibrations. Are some sort of roller ball system a better choice? The transport is a Denon DN-C680 broadcast cd player, and it weighs about 14 lbs.
