I have lots of experience with this amplifier and the M-22 and A-27 (M-25 with a built in pre-amp). I like to mate classic ss amps with exceptional vintage ss preamps (Klyne or Motif or other out-of-the-way designs) but I really prefer a tube pre in front of this classic amp. Example: CJ Premier 10.
Surprisingly, the A-27 integrated is less grainy than a M-25 and C-21 preamp.
