Good experiment.
So you are saying that your original experiment with the regenerator would coordinate with 4 above? Specifically, that the Entech was physically far enough from the noisy SMPS that there would have been no airborne RF noise coupling.
I am surprised that the regenerator did not have incoming low pass filters. Doesn't seem like that would be terribly costly, parts-wise, for such a device.
I use a Topaz isolation transformer and it works really well in my home / system. Output is balanced AC with an independent ground wire to cold water pipe (same as breaker box). I have an additional small iso transformer, with noise filtering, connected to my balanced AC power, that feeds my DVD player. DVD power is completely disconnected if I am spinning vinyl.

Follow Ups:
Yes, the original test the switching ps was way more than one foot away.
I also am running "balanced" power, via a single Isoclean PT-3030GII. Better than regen units that I had tried. (PS Audio & PurePower)
Amp is straight to wall. Source is on the above mentioned inverter.
I am very happy with the sound, and that is all that matters.
My 400va Isolation Transformer also providess 'balanced' power and really helps.
