Congrats on the new Class D monos. I own a pair in one of my systems and while they are by a considerable margin the least expensive component within it, they are not a weak link. They are very, very good.
Please do note that they take a long time to fully break in. While they sound good out of the box, they sound significantly better and are stabilized after several hundred hours - and probably best after 500 or so.
Enjoy!
