But be aware of the real nature of the problem. A CD player can recover up to an extent with its servo, then the error-correction, finally it fails and (should) mute. It's not going to distort the sound unless you actually start doing serious error correcting, and it's not going to damage the disk the way a turntable can when bounced. >...I don't own a CD player (yet), but have > several friends who've lent me theirs for extended periods > of time and I've found some of them very susceptible to > shock and external vibration. Treat this as a criterion when shopping. Some players are much more sensitive than others, so look for one that isn't too sensitive. Keep in mind that current technology produces CD players which will work in cars or as walkaround units, so a stationary unit CAN be stable. Most units seem to have rubbery (yes, I know it's really some magic polymer) feet which do a certain amount of isolation. It probably would be a bad idea to defeat this--for example, don't try to rack-mount a CD player unless it's meant to be, since that will couple vibrations directly into the cabinet from the rack. -- Dick Dunn {hao,ucbvax,allegra}!nbires!rcd (303)444-5710 x3086 ...Never offend with style when you can offend with substance.
