Tom, Happy Friday! You don’t have enough room treatment.. ; ) Kidding aside, with that marvelous system I’m certain you are getting exceptional sound. Your experience with aweful recordings sounding awful, and great ones sound great, surely is a sign of a transparent system faithfully reproducing whatever recordings you play?
And the biggest influence on sound quality is...
The quality of the recording itself.
Then the room, the setup, the speakers, and lastly the front end.
I've got recordings that make my system sound horrible, and I've got recordings that make my system sound absolutely wonderful.
None of the gear changes have had that much impact on sound quality.
