A friend of mine, a true STEREOphile, sent me some links today.
This was one of them.
Audio Myths Workshop

I quite like how this was plainly explained. No voodoo, no contention, just...that's how it works.

Very interesting! Once I saw that it was nearly an hour long I thought "meh"...I hit play and watched it all in one sitting! Very informative.

At one point the fellow says "i'm about to talk about a myth and some guys from this company are here upstairs and i even see one in the audience, so i apologize, but really, i don't..."

There was no rebuttal from the person in audience but then again, the whole talk and people's questions and responses may have been clipped.

Thanks for posting that, it was very informative and entertaining.
