I'v not heard the Belles. I'm using the Spectron Musician 11 on the Dunlavy Aletha speakers. The Spectron sounds so smooth and liquid. Its one of the best sounding solid state amps i'v heard.
Belles 350A or Spectron Musician II
Considering these two amps to pair with my Proac D15's and Cary 303/200 cd player. I've enjoyed my Bel Canto Evo 200.2, but I have the itch to change. I am intrigued by comments about Spectron perhaps outdoing Bel Canto, and also the great reviews of the Belles, particularly with the midrange, where Bel Canto seems sometimes a bit too analytical. Any experienced comments are appreciated.
