You should consider changing amp. But if you want to keep your Bel Canto Ref 1000 monoblock amps I would suggest getting a tube preamp. BAT makes great tube preamps. I would also look into the following tube linestage preamps : Audio Research, VTL, VAC, Lamm, Cary Audio, Rogue Audio, Primaluna, Frontier, Ayon.
Preamp Advice for my System
I am considering changing the preamp in my system. I have a BAT-42KSE and have started to look for something different. How would you compare a Pass X1, Bryston BP-26, or Classe CP-800 to the BAT? How are those 3 different from each other. The BAT sounds a little laid back to my ears.
