I have an RM-10, and just think it is great. Small, beautiful, and sounds wonderful. I think you will find only fans of both the amps you mention. I say you should buy both, compare them, sell the one you don't prefer, and then report back on this forum about the sonic differences.
Music Reference vs. Quicksilver
I am in the market for a lower powered tube amp.....small, moderately efficient speakers in small room. I am thinking about either a used RM-10 amp (35 watts our of a pair of 6bq5 tubes), or a used pair of Quicksilver mini-mites (25 watts out of a pair of el34 tubes). Any one got recommendations based on their experience? Appreciate the input.....
