When you say that you and Bill use your own ears and thus determined that class D suits you all I don’t believe anyone here would dispute this conclusion. Those who find class D undesirable are equally credible in their listening evaluations as well. One view doesn’t hold more merit than the other. The verdict is a split decision of yays and nays as with virtually any audiophile/High End topic. What impresses you or Bill may disappoint someone else who just has different taste and sonic criteria. Both sides of of this issue have IMO made compelling points. For there to be implication that if one is critical of class D they’re closed minded is misguided. It just means they listened and were honestly underwhelmed. We both would surely agree with the mantra of YMMV.
