Dear Friends, I like to buy Used Amplifier SS, Spectral DMA 150 Or Pass Labs XA160. My Preamplifier is Klimo Merlino Gold Plus +Thor and Speekers are Tannoy DC 10T,all Cable are Nordost. I like to know from your experience the main difference. Thanks very much for your help.
I'm with JohnnyR on that. Matching impedance between amp/preamp is important. I'd look either to change preamp as well or look for the models that are OK with higher impedance preamps such as McCormack DNA... or Bryston models.
