Line the underside and inside the top cover of your CD player or other component with $1.50 vinyl floor tiles from Home Depot. They damp the resonances just as well as the $10 sheets you can buy from the audio parts houses. Be careful not to cover any ventilation holes.

I'm on Fred's side that damping can improve the performance of a CD player. Especially when you consider how a laser in a CDP reads information off a CD. I'd also though that CD being a digital media would have its content read digitally (ie. reading 1's and 0's off the disk). But that's not true at all. The track on a CD consists of pits of various lengths and the laser reads the distance between the lips of each pit, which then is converted into a digital signal. To repeat, it does not COUNT and READ a series of 1's and 0's, but rather a physical distance between markers on a disk. Considering how cheap the laser and plastic lens are in a typical CDP, it makes you question how accurate CDP reads content on a CD. Any unnecessary vibration has the potential to mess up this reading process to create a playback that is even lower in resolution. Gar.

I don't know how serious miniscule resonant vibrations of the side panels might be as far introducing tracking errors to a spinning disk. I suppose that somebody has researched vibration vis-a-vis tracking errors, because it is important for portable cd players that joggers and others wear. I suspect, however, that it is pretty minor. "Tweak" would be the appropriate term. I do know that over 40% (it may be more - I forget) of the data on a cd is sophisticated error correction code (of various levels). So, there is quite a bit of room for correctable errors.

I've seen tweeks go so far as to change out the screws on the components in order to improve sound (no kidding.) The debate, if I recall correctly, was which screw material (various metal, nylon, etc....) sounded better. You can't make this stuff up. As for your inital post on dampening, I think it's a great idea. Almost as cheap as my 100# slate isolation table top (free from counter top mfg. dumpster) and my 1.5" wooded balls ($1/4 at craft store) that hold up my CDP.....Colin
