People who say that the new Krell amps are not musical and are fatiguing haven't listened to them. They are some of the best sounding amps I have ever heard and I have heard and owned almost everything from OTL tube amps, Audio Research tube and solid state, Conrad Johnson, VTL, BAT, Levinson, McIntosh and many more I can't begin to list. And in addition they will drive any speaker out there to it's fullest potential.
Levinson or Krell
I am currently putting a seperate listening room in my home and have listen to a wide variety of equipment. I have a pair of Wilson Watt Puppy 6's and I am currently shopping for amplification. I also own a Mark Levinson 38s pre and a Wadia 270 transport\Wadia 27ix dac. I have heard the Krell 350mcx's on the Wilsons and like the sound very much however I have heard lots of good things about Levinson 33H's paired with these speakers. I have yet to hear the Wilson/Levinson combo and I am open for suggestion.
