Interesting thread.
For the past few weeks I have been trialling a friend's Isotek 2k "Qube" powering my preamp, amp, DAC and music computer.
In a word - transformative.
Much cleaner sound, insightful, rounded, more natural.
Took it out of circuit for a few days and difference very clear.
After Munich I may well get a trail unit of the Power Inspired AG1500 to see if another step change.

“Music has always been a matter of energy to me, a question of fuel. Sentimental people call it inspiration, but what they really mean is fuel. I have always needed fuel. I am a serious consumer. On some nights I still believe that a car with the gas needle on empty can run about fifty more miles if you have the right music very loud on the radio”

What is an easy way of measuring the quality (with audio in mind) of domestic mains electricity?

possibly the easiest is to borrow a mains regenerator. if it improves things then your mains isnt perfect. if it doesnt, then dont worry

True. However I'm always wary of the placebo effect - no doubt having been caught out many times. Nice to have reassurance with measurable stats. But having said that I do think I got a marked difference using an ISOtek Qube recently so perhaps an AC regen (such as that provided by Power Inspired) will be as obvious.
I see that you have the AG1500 regen unit. Did you notice a significant difference?
Interestingly in June's edition of HiFi News' there is a relevant comment (p116) on this subject. The comment also discusses the idea of "Variable MultiWave" which, to me as a layman, seems contra intuitive to a pure wave (as done by say the AG1500). But like you the comment says to try things out.
