i do not even care, what may be best for you may not be best for me...
i use whatever method gets me there....as long as i am happy with the results, then that is it....
there is a sea of difference between talking here and building amps....our experiences will never be the same....
never an issue with me....if i am happy with what i built, then that is it...
how can a design and build that makes you happy be a bad design?
@Mark.
I'm only trying to cover the generality of historic installations. Griping about detail like this is a waste of time. Of course the load return will be to the closest PSU reservoirs, but this makes absolutely no difference to the principle. I'm talking about general principles, not individual installations. You have to apply some effort if you want to understand this, not just throw in every trivial objection you can think of.
Everybody else might like to consider that the load return is the dual of the send, not the power rails. The frequency of the AC in the rails is twice that in the send. We have no real interest in what has gone round the loop from the amplifier to the speaker and back, we're only interested in what's jumping off the rails before it gets to the amplifier. As such, it won't be reflected in the load return. To that end we're only interested in the load return as a conductor to the star point.

Sorry, cancel that sentence, it's in error. The frequencies are the same, the harmonics in the rails are worse. It's fullwave rectification I was thinking of. The rest still holds.
when something works fine, i leave it alone...this is me....i hear what the others say, but it has never been my practice to use the pcb ground traces as speaker returns....just can't make myself do it, am i nuts or what?
and with this i am closing this thread.....it has run its course....readers will find good stuff here and i can not think of anything more that can be added here...- Status
