I am going to research what goes best with Musical Fidelity integrated amps.
MF amps sound best with many loudspeakers. I'm going to guess but you had a solid state amp of perhaps not the best quality. I think you just need a little time to acquire the taste for the new amp and maybe a little break-in time? I'm just guessing but nobody dislikes the sound of a well matched MF integrated that I know. So let the cat out of the bag, what MF is it and what was your old amp?
