Vance...
I'm guessing you didn't read the original thread...
(I don't blame you, it is really long, and gets downright adolescent at times.)
In it, Bruce emphatically (and repeatedly) states (I'll paraphrase):
I'm NOT a mastering engineer, but I know enough about the process to safely say that it is something you cannot do well at home, by yourself, on your mom's computer. (I had to keep your "mom's computer stuff"

)
He also insisted that someone who knew what they were doing did the judging. Shailat has arranged for that. We opened things up for the masses here for fun, and education.
So, this little exercise was concocted to try to prove a point, and hopefully be educational.
Is it silly? Yes! But I believe that it
is educational. One of the points it has proven is that many here don't have the ability to pick out a good master against a bad one. Without knowing which is which, looking at the current results, and reading between the lines, somewhere between 18-50% of the people picked the original!!! (There are also two people so far, who are willing to admit that they don't know what they're listening for...)
Lastly, you commented:
Listening to an mp3 is not the best way to judge a mastering job but hey it's only my opinion. I'm certain we can all agree with that statement, but that is why I have the .wav files (compressed to ape format) available.
Finally (uh oh, what happened to Lastly?....

)
In concession to Bruce, although he didn't specifically ask me to do it, I purposefully placed the quotation marks around the word "Mastering" in the subject.
So, if you wanna join in on the fun, come on in.
I commend Bruce for giving us the time.
