Cary 308T, Revox B226-S, and Studer A727 still fetch pretty good money on the used market.
Things that make you go, "Hmmmmm...."
the Muse was about $10k new years ago, I paid $650 for it on Audiogon
What CD player can I buy that will hold its value and not be near worthless in anything more than a few years?
New or used.
