I went through a similar choice a couple months ago. I bought a Parasound P6 to go with my A21 and I thought I would be happy. Wrong. The P6 went back within 48 hours and I tried the MF M6S Pre instead. Now I couldn’t be happier. The P6 had all the features, but the M6S has the analog circuitry that makes for great sound. I would bet on the MF.
Musical Fidelity m2si or Parasound Newclassic 200 for Dynaudio Emit 20's
Considering both of these amps for my new Dynaudio Emit 20’s. I am also intrigued by Peachtree Nova 150. Any input would be greatly appreciated from those that have owned or had experience with either of these integrated amps. Thank you in advance.
