Looking to replace my (Mcintosh)

Check out the new Krell Duo 300 XD. This is a pure Class A design that will blow you away in terms of its musicality, sound stage, deep bass and sheer presence. I have had the Krell 400 cx and couldn’t believe a unit that consumed so little power relatively to the old “muscle cars could sound so good. This unit sounds BETTER. I also have the Chorus 5200 for surround sound. They share the same topology. 

Greetings,
and thanks to all who have posted, i have decided to go with the (Mc 72 or 7300) due to physical restraints (room size) .  I might up grade my speakers (patinum audio solo, and KEF LS50) soon, what do you think would be a good match?

7100's bridged are 8 ohm only! Period.
