I haven't heard the Bryston, but I have heard the Krell 400xi driving many different High-End Speakers, including: B&W 80X, Revel, Sonus Faber, JM Lab/Focal and Krell's own Resolution and all sounded excellent driven by this entry-level Krell Amp. Don't let the price fool you, this Amp. dishes-out all that could be reasonably needed in all but the very best systems. It's well deserving of it's current "Stereophile Class A Rating"!
