Mac, if you are referring to the ability of our auditory sense ability to replace missing information, I understand about all of that...it is what the mp3 format is based around, this ability for our systems to replace the missing info.

I have taken "blindfold" tests along with some other friends who wanted to try it out, and yes, we were not perfect. But when I can here the difference around 70% of the time (some were better, some where worse) then it is unreasonable to say it is all in someone's head, and that they "think" that they can tell a difference.

It is like the arguments about how a DAW sounds, "Do the null test!" is the cry, but it is funny that folks can usually pick their favorite DAW from a list of tracks that have been played back thru several DAW's, when they all use the same Master track for all of them.

It's all horses for course really, and something that will always have folks on both sides going "Oh Yea?!"
