looking for best isolation platform for CD player

Vibration isolation is not a problem unique to audio. At work we use a 8-inch dish of mercury as a reflective surface for optical measurements of true horizontal. (The mercury surface is a perfect level reference). However, the slightest vibration causes ripples on the mercury which makes the optical measurements difficult. Even with the mercury dish on a 3000 pound granite slab on a pier sunk 60 feet into the ground we had ripples.

Our problem was solved by an active (electronic) vibration isolation table, similar to one that you can check out at:

If I recall correctly it cost us about $3000. I can't see needing this for a CD player, but it could be good for a LP turntable. Be the first on your block to have one!

"I can't see needing this for a CD player..."

Actually, CD players respond very positively to vibration isolation, the better the isolator the better the results. One reason for this might be the small coil spring assembly that supports the laser itself. This laser assembly has a resonant frequency of approx. 8 Hz. Structural vibration capable of causing a tonearm or cartridge to resonate will also cause the laser assembly to resonate...

Geoffkait...How then do CD players work so well in automobiles, and even in portable players while joging?

Error correction is one reason car and portable cd players work so well in poor environment.. I have implemented many ways that make for less error correction and therefore better sound..Tom

The more robust players such as those for jogging feature data buffers, so if there's a momentary loss of data due to shock, it is transparent to the user. So this is not error correction per se but data buffering.
