Thanks for the posts. My living room will not accomodate the Mahlers. I am keeping the Beethovens and will try matching them up with the Bel Canto EVO.2 amp and a tube pre, most likely the Joule Electra LA-150 (I also considered a Rogue, but am intrigued by all I've read about the Joule). I have heard it is a good idea to run the Bel Cantos as monoblocks, so I may get another one later on if I like the one I get now.
Next I need to settle on a new CD player, probably between a Resolution Audio CD-55 or a Meridian 508.24.
I haven't pulled the trigger on any of this yet, so if anyone sees any fatal flaws, I would like to hear from you. I have precious little experience in high end audio, but intend to experiment until I get my system "right." Luckily, I live close enough to Jud Barber to drive down and audition the Joule amps at his house. That ought to be a blast.
I sincerely appreciate everyone's help.
