I have used the EAD Powermaster 2000 and CAL MCA 2500 with great results when biamping. I have also used Bryston PP120's, Linar Audio 250i, and Sim Audio W10 monoblocks with good results. It depends on your liking and pocketbook.
Recommedation to drive Electrostatics? ML, Inner?
Any recommendation to drive Martin Logan, Innersound amps? Tubes vs. Solid State? Thoughts, recommendations appreciated....
