2026 best deal in audiophile class D stereo amp?

My new super incredible speakers (canton reference 2.2 dc)require power!  Looking for something that will give them 300-500 watts into 8ohms of quality sound.  I’m a tube guy (SET amps) and hoping for something that’s worth it in the $1k to $2k range.  Lot of deals in the used heavy duty class a or or a/b but,  I’m getting old and it’s just as good and only weight 20lbs.... why not try it??  

this...?
