I agree with most the things listed above.

Gotta disagree with a couple, though.

Working with power for server rooms, I know power conditioning is *NOT* snake oil. It may not have a noticiable effect on audio, but it's a good thing for your electronic equipment, no matter what it is.

Also... A/B testing is worthless? Bull. It's the only way to test speakers. Audio memory is short, so instant switching is the best way to tell the difference. When I tested my Ascends vs. Polks and JBLs, A/B switching was what showed how clearly Ascends were better.
