I concur with the folks who say upgrade your front end. Your CDP is not at the level of the rest of your system. If you don't mind saving some money, you could check out a Shanling CD-T100 with NOS tubes. Otherwise I'd listen to Linn's best, SimAudio, and all the other guys' suggestions too.
Once you get your new player, look downstream. The suggestions about AC lines and room treatment are nice too, but IMHO get a new source first.
