I will conduct a bit of forensic audio analysis. The GCC dates to about 2005, WFS STI 500 dates to about 2010, and Peachtree Nova 220 SE to about 2014. I had a pair of PS Audio GCA 250 amps - wow, that was a long time and a lot of gear ago! I had forgotten about them until I saw your post! :)
Looking at the class D amps you used, I understand why you drew the conclusions you did, but you did so with equipment that is about a decade behind, irrelevant to better system building today - at least for anyone who is wanting to be using better class D amps and putting up rigs that are far superior in terms of performance. :)
Conclusion? You are the better part of a decade behind due to reliance upon used/budget gear, it seems. This puts you out of touch with what is happening NOW with class D, and the conclusion you have reached is about... a decade off. You have used dated, fundamentally surpassed class D, and I do mean fundamentally. As it appears you have no experience with the latest crop of class D modules/designs, your premise that Class D is inadequate is colored by your lack of experience of current products. Consequently, you perpetuate what are now misnomers about class D that no longer pertain.
I actually address the perception/wrong conclusions that you and others anchor to in my article regarding the Legacy Audio i.V4 Ultra Amplifier published at Dagogo.com
It is up to you whether you wish to be educated on this topic, or whether you wish to argue from a position inexperience (that is, ignorant in terms of experience of more current class D amps), or one that suggests that older components will obtain the same result as current designs - typically, a budget audiophile perspective. No disdain toward it, as I was a budget audiophile for many years. However, it does not put the person in the position of speaking with authority on what is happening now in regard to sound. I don't mind discussion, but am not interested in arguing with people without experience. I suggest you need to moderate your declarative tone. :(
