Go listen to them. You will never go wrong with anything that says Krell on it I once hooked up a 400Xi to Martin Logan Aeons. The lady wanted to know how far the volume knob went so I told her to turn it up...and up....and up...until it stopped at 151. It was LOUD!!! Nothing broke thank goodness. Excellent piece at an excellent price. GO with the Krell. But listen first!
