CD player vibration control ..................

I've been an isolation freak for about 15 years. Started with solid oak planking and then maple cutting boards before Peter Bizlewicz got one of his early proto's into my system. Since then, I've had the chance to listen to most of the usual suspects in my system. I remain an ardent employer of Symposium - I have Ultras under my components and my speakers; Roller Blocks under my AA and my BAT amp. Now I'm waiting for Symposium to bring their new Series 3 to market. This will be akin to another component upgrade but I have heard the prototypes under Wavac and Jadis amplifiers - not to mention an Audiomodded 777, and the results are extraordinary. These are expensive products and, unfortunately, there are few US dealers - most of whom neither know the products, much less how to effectively demo them - so your best best is to travel to RMAF or CES to hear for yourself.

All of my cdps - Meridian 506.24, 508.24 and 588, and my AA Cap Mk II - have greatly benefited from isolation and damping.

Rotarius, most manufacturers do provide data on their websites - though generally not in quantifiable terms. Some Agoner's systems are so sensitive that even slipping a piece of paper under an oem footer will produce a detectable difference - if the listener has sensitive ears. There are also the suggestibility and predisposition factors. So, even if measured data was presented online it would provide very little information that could be directly applied to one's own system. That's why A/Bing in your own system is the ultimate test.

Having said that, anyone interested in learning about isolation, damping or draining of unwanted energy can visit the websites at Symposium, Silent Running, Townsend, MIB, Halcyonics...whatever...to help determine which approach might be the most effective - or pertinent - in improving the sonics of your chain. Be advised that there are many imitators in the marketplace who will attempt to play off a successful device by altering the structure or resource material in an attempt to circumvent a protected design (or to spend as little $ as possible in the mfr'ing process!). Further, I doubt that many DIY isolation devices - if any at all - will be as efficacious as those whose manufacturers have been trumpeted here on Agon. Despite claims to the contrary, you will get what you pay for with these tweaks - but you have to hear them in your system (employed in the fashion for which they were designed) before you can draw any serious conclusion.

Rotarius, I could round up specific or anecdotal material to answer your question but I wouldn't be doing you any favors. I recommend you visit as many sites as you can to garner the information you desire. I can tell you that Symposium and HRS both address - to a lesser or greater extent - their engineering and manufacturing philosophies. Both describe or define basic acoustic law, i.e., basic physics. Most mfr's will tell you what energy dissipation issues their products will address, but rarely do they tell you "how," other than in the most basic language. Obviously, you can google a lot of information regarding airborne or structure-borne vibration. But the best technical/copy writer will not be able to impart to you the true value of any isolation device as well as practical experience will. Systems can be similar but sonically dissimilar so that drawing an mutual conclusion is, essentially, foolhardy.
