Power conditions for Integrated Amps

All my gear is plugged into a Nordost QB 8. Excellent performance. 

I wonder if you were to do a blind test to 50 people or more if people would hear a noticeable difference in sound quality.  If they would hear a difference, what would they year.  Would it suddenly grab their attention?

I wonder if you were to collect 50 people whether they would all have same situation with their electrical? Of course they wouldn’t.

If we start out in different situations, and we don’t know what the differences are, what is the possible point in comparing? None. We’re just misinforming one another.

Thanks Everyone! Lots of helpful opinions and options. Now I have to get off my butt and try a few....
