Wrong and wrong... again. Sure, you can Drive a Pass Labs amp with single ended signals, but you get less gain, half the power, and ten times the distortion. You'd know that if you read the Su-Sy article. You'd also have known that there are definitely balanced amps out there, to, which is the ONLY way Pass amps with Su-Sy work correctly.
This is what the B1 looks like.

That's not what you've got. That, and the schematic doesn't make sense. P1 isn't the volume control. It balances the voltage reference to the FETs. The volume control is obviously the LDRs that form the divider at the input. I don't understand why you keep posting that.
Beyond all of that, Nelson didn't invent that topology. It's been used in dozens if not hundreds of input stages in amp and pre-amps for eons. You can find him saying that at Burning Amp 2015 when he discusses the nuances of that complimentary pair.
