Isolation devices and CDPs


Do isolation devices really work under CDPs (I own an EAR Acute)? If so, which isolation devices work best? And how/why do they work?

Nice piece of equipment that deserves special attention. What we all need is what Equa is referring to, namely a device that isolates and dampens. The latter is oftentimes forgotten. I have used many expensive isolation devices over the years and typically there is an improvement in clarity. However, the greatest improvement I have experienced to date is use of EquaRack footers which isolate and dampen. Bearing footers are the best for front end equipment like your CDP. I use them under my transport. I use regular footers under the rest of my equipment. The improved resolution and inner detail is amazing. I like you have my equipment stand sitting on a concrete basement floor and my transport is built like a tank weighing 65 lbs. Yet the bearing footers created a marked improvement. So isolation, though important, is not enough. Don’t forget about dampening.
My Acute sounds best with a large buckwheat pillow under it (also under my EAR 324 phono stage). However, I would eventually like to use a Townsend Seismic Sink. Otherwise, the Acute (and most of the 100+ CD players I've tried at home from the 80s) sounded worse on their own legs/feet, best with the buckwheat, sometimes better on navcom or silicone types and worse with Aurios. Stillpoints were okay but buckwheat (inexpensive but uglier) beat them all. Ask Tom Port of Better Records-his top choice.
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
