I conncur with zd542, Krell has something that will out perform the simaudio, maybe move up the amp chain to mono blocks could do the trick, I am sure the 900E krell amp is better than anything simaudio makes, I am supprised that the 402E amp got beat in your opinion.
Simaudio 870a over Krell 402e?
I have always been a Krell guy until I purchased their Cipher CD/SACD player. Long story short, I now own a Sim 750d CD and a Sim 740p pre and have been absolutely FLOORED by the two pieces compared to my Cipher and 222. I would like to trade out my 402e for the new Sim 870a to complete the package, as it has been such a step in the right direction...but I can't audition the amp first. Anyone heard the new amps? Thanks, Beach.
