But only George can hear it.
Not just me sunshine, everyone else that hears something wrong in the upper mids/highs with Class-D, you just don’t hear it, and choose to ignore that very big fact.

You say you can’t hear it that’s fine then live with it, but stop starting new Class-D threads to look for confirmation/cred from everyone about how good it is compared to the best linear amps.
When that old Class-D technology moves forward instead of sideways with the new GaN technology and make use of the 3 x higher switching speeds available, then it will compete with the best linear amps.
I’ve said it before, when Class-D can finally drive a pair of speakers like my big ML’s, Wilson Alexia, Alexandria or Watt/Puppies to their very best like linear amps can, then it will be time to sell my inefficient boat anchors, to purchase them.
