SS integrated for Proac 2.5 - Plinius or Unico?

I am runnng Proac 2.5's with ARC tube amplification (LS-7, VT-50). They sound great, with accurate tonal balance, extended lows and wide soundtaging. I am thinking of switching to a SS integrated amp to avoid the heat and hassle of maintaining tube amps. Is there a SS integrated amp that has a presentation similar to what I am getting with the ARC combo? Oh, and I also want a phono stage. Considerations are Plinius 8200 or 9200 or Unico. I've heard the MF A300, and it has nice tonal balance, but is not as transparent as the ARC. Suggestions?
