The difference is that the connectors on the module are very close to things that can interfere (or cause unwanted feedback effects), while you usually don't have any HF sources or sensitive electronics near the binding posts on the rear panel.
Back to understanding standby.
So is the amplifier module's standby functionality equivalent to just muting the source and leaving the amp fully on?
I do understand that with no input signal, most of the switching transistors are probably off and the quiescent heat produced should be much lower than when playing at loud volume levels.

No. The nAMPON control input enables/disables a lot of the amp circuitry, and the SMPS Standby on the power supply turns the amp completely off.
Sorry, was called away from my computer before responding to this second part of your posting.
With no input signal (or a signal of zero amplitude) the transistors are still switching, at a 50/50 pulse width, but losses are at minimum. In a class D amp, the switching transistors are always switching between fully on and fully off, but the duty cycle / pulse width changes with the input signal.
Ah, that makes total sense, now that i think through.
So just muting the source is going to be close to playing the music and standby is the right way to idle the amp powered on.
Probably not going to muck around with my current amps to incorporate standby. Something i will definitely do on any new build.
If only i could get hold of some NC500s module for a reasonable price
Boggit's price is great though.
For more than a few hours, standby is the way to go, but power consumption when fully on but not playing anything still uses considerably less power than playing at full volume.
There is nothing wrong as such with just switching off mains power - the SMPS has a soft start function - but I definitely prefer to put my amps into standby when not playing. Fortunately it was easy for me to have the source do that automatically.
I agree the best way for the on/off switch would be to put the amp and more importantly the power supply's into standby mode. The PSU's require a positive voltage in order to shut down. This would require an external voltage supply and an additional circuit board and cost! Its will be something I will look at doing in the coming year. You also have to have room in the case to add this feature. It would be ideal though.

Leave it on playing music around the clock for years. They will be fine. They're not like tires on a car, or brakes that wear out with use.

Hard to say what's worse. Constant on and off cycles, or next being left on. The temp is not very hot when left on idle.
That doesnt make sense. Nobody is taking about mechanical wear here.
These are densely packed components and I cant believe some of them especially the electrolytic caps dont have any thermal ageing. Granted they are rated for some temperature.
nAMPON appears very simple to use, to me it makes sense to employ it.

Yeah you're right. Maybe after 10 years or so you may need to change out $3 worth of caps
Nothing I'd lose sleep over over. By then Hypex will have the Ncore 3 out anyways
Unlike the big old dinosaur Macintosh's etc.

Really appreciate your sense of sarcasm. Very polished indeed.
