I use the 6922 version QS preamp with my Mono 120s, and it's a great match. I also use an Audible Illusions M3B but have to use line attenuators to knock back the gain. This combo also sounds awesome.
Which preamp for Quicksilver mono amps?
Anybody has tried Quicksilver monoblocks with different preamps?
Is Quicksilver preamp a good match?
If not, which preamps have you tried and which do you think work better?
