Other candidates to consider are the Krell 400ix and the BV Audio A300s, which is a true dual mono design and will supposedly drive anything. There is an excellent review of the latter at STEREOTIMES.COM. Also, for what it's worth, one of the English magazines (HiFi News and Record Review, I believe) was much less enthusiastic about the Plinius 9200 than the Krell 400ix.
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
