Class-D load vairation

Completely agree , load is always required for d class amplifiers, whose have output filter .But i think load can be reduced (more ohms dummy load than normal), to reduce heat / energy and so , still having amplifier operating properly.
 
Ok , would be probably modern solution . But as op mentioned , he has transformers already, also output socket and switch are connected too, so such device would mean that earlier done work was kinda useless. Also , this optical to rca converter requires power to operate , how you will control it's psu , while turning off tv with remote in example ? It will stay always on probably , thats acceptable not for everyone.
These simple adapters draw maybe 2 watts, so what's the issue with having them plugged in?
As for me, mine's plugged into the accessory AC on my stereo receiver, so the power supply (wall wart) is on whenever the receiver is on.
I hope that answers your questions.
 
That would better be answered by op , what setup it has , and what's acceptable and whats not for him. Personally i'm disappointed in many devices high consumption of standby or idle , also we had big jump in electricity prices , so who knows, sometimes every watt can matter ,if there's lots of devices, always plugged in . Also always plugged in things may fail easier , if there's power failure like overvoltage.
Everyone has its own way for solution of existing problem.

I think you're over-worrying or obsessing about things.
