That's probably just the transport acting up so it could be a good deal. Denon sold a lot of these players so it shouldn't he hard to source a replacement drive or just send it back to APL and have them do it.
As for my player, I can't see that I will be upgrading any time soon as the player has everything I could ever want, CD/SACD/DVD-A capability, built in volume control and a digital input. It uses a tube which is excellent and in current production so there is no tuberolling non-sense. I do wish it was silver (I may gut one later on and swap panels) and I need to find a good, yet small 230v/117v transformer that can fit inside it but that's all. While writing this up it looks like Plitron may have some 100VA units that will do the trick...
