You are on to something, QH. I rarely chime in on this because the audiophool community simply can't believe it. In my case, I choose to believe my ears.
The initital round of recievers didn't make it for two reasons, both based on "Joe Average HT"
1. Too light to be credible.
2. Too cheap to be credible.
What's worse, the audiophile community suffers both of those as well. TBHY, I am pretty sure some of the issues reported occur in the listener's head due to a simple inability to accept the idea that one of these dang near free devices produces sound (MHO) equal to any SS amp at any price, and matched only by tubes.
First pany I got I sold ALL my SS amps. Kept my tubes but if I hadn't already had them I wouldn't have spent the money on them unless I just had excess cash and wanted one nostalgia purposes. I collect kerosene lamps, too, and prefer them to electric lights.
There remain more than enough areas where one can spend as much cash as one wants and hear significant differences...but amplification, at least for some of us, isn't one of them.
BTW, you have opened a KING SIZE can of worms...
Hope you are hungry!
