Krell 575xd monoblocks


I am considering purchasing Krell 575 XD monoblocks.  Currently have Duo 300 xd.  Does anyone have any experience and/or opinions to offer?

The 575’s are amazing.

 I’m sure they will kick your speakers a$$ and give you eargasms. 
 If I had the coin ide get krell!
 Great stuff, only issue is cost of repair, and longevity of them.
 Their great maps, and a great company.

 Fabio uses Krell!
Expecting delivery this week. Can’t wait. Still listening to my Duo 300xd, which is listed for sale. It’s a great amp, given me a lot of pleasure!
How did it work out? I have the Duo 300 XD and am considering the same upgrade.
The 575’s are more amp than I ever thought I would have. My ears never tire of them.
