This is the clearest presentation I have ever seen about digital audio in general, even if it's not trying to be that general.
It really is peculiar how many otherwise technically minded people with experience in DSP and/or audio somehow think there is something "magical" outside of what can easily be proved, and this video demostrates. I don't doubt that there will still be those who will contest the results, regardless.
I did especially enjoy the use of analog test equipment, in an effort to put to rest any conspiracy that the talk was flawed by being digital. This must have taken lot of time to put together, but it's certainly worth it. I'm going to drop this URL into a lot of debates in future.
