To answer the philosophical questions first - at least from my view:All apply, are measurable, BUT we have no correlation of the measurement to the brain of the listener(s).
We are all ultimately responsible for our own behavior, so I believe that the personal perception is the issue to target. My experience with continuous musical training constantly shows me how much "control" we have over our perception. We have syllabuses to train musicians but not listeners of music. This pretty much means that all results for "audiophiles" are more chance than plan.
As far as power supplies go, I am not aware of any serious attempt to even locate the electricity "problems". We have audiophile drivel about noise, impedance, even the quality of the wiring/outlets. All of this with no correlation to anything. Are the switched power supplies the source of all evil?
My testing has been to take a battery driven source, plug it directly into the multi channel amplifier and listen for an extended time in this configuration with music that I am familiar with. Then I add the preamp/buffer which is plugged in to AC and listen with the same source - now only with the buffer in between. Not having "bad days" with either set up (or a "better/worse" result), makes me lucky I guess. i know that Paul S went through quite a bit. I have not read everything that he probably wrote however.
I have some first hand experience with UPS regeneration but generally in Germany do not seem to have the problems with electricity that are often reported here.Rerurn to Romy the Cat's Site
