"I disagree and would say that a power supply can do nothing more than filter grid issues. For example even a rechargeable battery driving an AC power generator needs to recharge off the grid eventually. IMO the only true isolation would require an alternate energy source."

Sounds more like a semantic problem than an engineering one since the only thing required is that power supplies adequately "filter grid issues". If a stereo component is incapable of performing to specification without external power conditioning then it is simply defective or deficient.

The rub of course is the specifications, specifically that there are none. Lacking any enforced standard for power supply rejection and any useful standard for performance the consumer bears all the risk and expense. I sure wish Stereophile would pick up the cudgel on this issue and start measuring power supply rejection and EMC. It isn't difficult and would be a real service to everyone concerned with high-end audio.
