Having done this ( and a thousand other versions ) test more than I EVER care to remember ( I've forgot MORE about this subject, than most people even know!!). I can weigh in as THE expert hands down , worldwide !
First I will describe my mistakes, then I'll give my unsatisfying opinion. I was in the navy ( got out as a 1st class ET ) when I first started to experiment with audio fidelity. Mp3's and low bit rates are one tiny portion of my research. According to the US Navy I have perfect hearing. 1) Don't EVER use ear or headphones to conduct these tests, they 'through off' the minds ability to percieve auditory slight changes.
2) Until I tested with my Yamaha cdc 865 and my 750w Carver amp coupled to a pair of Infinity SM 152's, I was kinding myself in attaining ANY accuracy in my results, you've GOT to be able to reproduce the electrical to mechanical B4 you hope to make comparisons.
3)First establish highest possible 'music/sound' preception with the highest quality equipment you can get, this baseline may seem high, but after you do it, you'll know why!
Opinion: WMP variable bit rates and/or cda files are THE ONLY acceptable listening experiences, the rest ( and especially mp3 crap ) is GARBAGE !! Until you've been to the 'promised land' even garbage can sound good !!
