Sorry @charles1dad. You and I are often in agreement about many things, but this is a bridge too far. Think about it. I admit that I have also listened to many systems over the year on youtube, and that's the very reason that I know that it can't be trusted, because usually, they all sound good!
As an aside, I really find the OP's attitude a turn off. He presents his system and his methods as the best and only way to do things which is silly. There are many roads to the destination, and to say for instance, that grounding is more important than, or a substitute for room acoustics seems to be really off.
