"A CD player is more problematic, but they all contain extensive error correction circuitry anyway."
IMHO, a CD player on a sub is ENORMOUSLY problematic. Error correction or not, the sound of a CD player is degraded terribly by vibrations (though I seriously doubt the equipment would be damaged, at least over the short haul). You really shouldn't be investing in high end equipment if you are going to use this sort of set up. Severe vibration can degrade the greatest of digital sources to near Best Buy level of performance.
But, Eighthcircuit, don't feel bad for the question. It is perfectly appropriate to ask if you don't know. I myself was skeptical about all the fuss about vibrations until I demonstrated it in my own system. In my case I moved my system from the side of the room (where it was to the side of my speakers, supported by a beam running underneath the floor, and by a custom fitted cabinet wedged into an alcove in the drywall) to the center of the wall and in between my speakers. It was all motivated by a desire to buy high grade speaker cables in reasonable length runs. In making the move I even added a high quality rack, but it simply couldn't begin to make up for the change in support in the flooring and cabinet, and my system sounded broken in comparison. This was in a house that is actually quite well constructed. The change lasted less than a day, and I am now a firm believer in the perils of vibration in audio, and happily use cheaper cables in long runs.
