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?

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.
