If Krell got a lot of tracking problems, you should probably look elsewhere.
Since Denon 2900 is a universal player, most manufacturing cost is actually spent on DAC and different decoders, rather than optic and reader. I don't think it is a good idea to use it as a pure CD transport.
I have some experienced with several good old CD players (Revox, Studer, Naim, ARC). All of them sound better than the new midrange players. I recently replaced my Marantz 8260 (stereophile class A) by a 10 years old ARC CD1. The improvement is huge and substantial. Even the CD layer sounds more smooth than the SACD layer on 8260....
