I believe the CP-72 is the 5 disc version of the RP-82 (could be wrong, I'm relying on memory here). Good unit, but I have seen comments about the tray mecahnics not being the most reliable. Excellent PQ AND it plays 5 CDs. For $85, it's a steal. However, if you can grab a RP-82 for $85, get as many as they will sell you. This was the reference player about 1 1/2 years ago and people were going nuts trying to find one last year. I know I looke long & hard and could not find one. I ended up with the Denon 1600 (which uses the guts of the RP-82) and I'm still thrilled with it.
