Isolation devices and CDPs

This is a great topic. I thoroughly enjoyed Equa's technical explanation of damping and isolation. Very well done. I realize these are not on the same par as Equa's "Footers" but I've invested in Vibrapod Isolators. I have 3 sets in use (two CD players and one DVD player). No question they make a sonic difference (improved soundstage and more defined bass) as well as eliminating skipping and jittering. More of a budget isolator.

good read on isolation devices and comparison of products.

Also check out Herbie's Audio Lab... a number of interesting, low cost options. One thing I've been trying to good effect is placing his grungebuster dots between my cones and components. Seems to make a nice improvement - particularly under my CDP. YMMV

I think the EAR Acute in particular benefits greatly from 2 things. 1. Tube rolling, I found the Amperex US 7308 very good and the Seimens early CCa excellent when compared to tubes provided. Several others I tried did not beat the stock tubes. 2. Vibration isolation and mass loading.
Overall I feel the Acute really sounds excellent with these 2 tweaks. My only criticism is it could have been built a little better but then the price probably would have been a lot higher.

Rja: What have you tried for vibration isolation?
