Krell KRC-3 Questions

Couple of questions for any KRC-3 owners out there: 1) do you leave your KRC-3 on all the time? and 2) can you recommend a cd player with balanced ouptuts (I am prepared to look at new mid price and used high end). System is KRC-3, KAV250a with Celestion A3's, Kimber PBJ interconnect for pre-amp to amp (need to upgrade - any ideas?) and Van den hul cs122 speaker cable ( bi-wired). At present using an old Cyrus CD6 as source and I must say sound fabulous but clearly source is weak link.

thank you
