B & W 802 Nautilus and Monoblocks


I have B & W 802, and looking for amps. Which amps would be a good match----Classe CA-M400, Pass Lab X600, or Krell MCX350? Thanks for your opinions

Bryston 14 b sst or McCormack DNA 2 LAE or DNA-500 for the ones you listed the Pass X600 I love those amps, but for the price the DNA 2 LAE on the used market plenty of power.
