Bryon, when you speak of power quality, I assume you are talking about the quality of the AC line, correct? The age old question about why our systems sound better at night? When there is less stress on the power grids and the electricity is better quality? Or dedicated lines taking things like refrigerators or air compressors off the lines of our audio equipment?
If so, I think the answer is just the equipment is better able to perform to the best of it's ability when it is driven with better, cleaner power. When fed dirty power, any piece of gear can struggle. That is why some manufacturer's believe that a battery supply (DC) is the only way to provide true clean power. I believe the answer to your questions 3,4 and 5 is simply that with cleaner power, the equipment is getting what it needs to reveal it's potential sound quality.
I suppose it is similar to how a car performs using different octane levels of gasoline. Yes, in cars too, some manufacturers believe that a battery is the best source for clean power.
Cheers,
John
