You may bypass Pathos and Unico and stick with your first two choices.
Integrated For Revel M20s
I just purchased a pair of Revel M20's on this site for a second system. Any recommendations on an integrated for them? I'm thinking possibly Plinius 9200 or Musical Fidelity 380, but have not ruled out lower powered options like Pathos Classis 1 mk2 or Unison Unico. Any feedback would be appreciated
