FWIW, I thought the Bel Canto REF1000Ms did well in its price bracket. I compared it to Bryston Class AB gear that cost a bit more and it was not a clear win. The BC had superb bass control while the Bryston had a full midrange. I found that using an ARC tube preamp (Ref5) put the balance strongly in the Bel Canto side.
I only found a decent upgrade over the BC by going with an Electrocompaniet Nemo or Plinius SA-Reference that was well over 2x the price of the Bel Canto
