looking for best isolation platform for CD player

"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...

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.

makes sense; the laser reading process seems critical to final outcome. The off the shelf player does OK but not anywhere near perfect.
