I think some of these people are so far gone into their pursuit of perfect sound quality that the actual music eventually becomes secondary.
The guy in the original post is a classic case (it's a genuine post from the forum at stevehoffman.tv from at least ten years ago that I saved in a text file because I thought it was funny; yes, I posted the FAKE above; I found it while I was going through some old garbage I have on flash drive). He has MULTIPLE COPIES OF 'SPORTS'. WHY? Because he wants to compare the gawddamn mastering.
