The title says A REAL Test! This is most definitely NOT! the way a test is/should be conducted...not even by a long stretch!
The resolution doesn't matter, analog vs digital doesn't matter, how wrong/right the participants were doesn't matter!
Performing a test whereat humans are testees, isn't an easy thing to do. One should strive to avoid the human factor as best as possible, meaning...oh boy, where to start with this nonsensical "test"?!:
- they lost me with power cables improving sound...though I clicked some more minutes here and there
- comparing a lacquer to a digital recording...yeah, right, we all play lacquers on our turntables...not to get into the difference about mastering analog vs digital
- babbling all the time, patting their backs all the time, even during the "listening sessions"
- blinded, double-blinded, AB, ABX testing...they couldn't care less
- setting the loudness of the two sources as close as possible...yeah, I'll just have a look on the handheld meter, here and there
- obviously they all sit in the sweet-spot
- the rubbish is going on for 2 hours, 7 minutes and 32 seconds...yawn!...what's the minutage of actual listening and the ever ongoing yada-yada-yada?!
- human audio memory is to short to discern the sound (differences) between them switching from one source to another...whilst babbling all the time
- and so on and so forth.
I'm not the least interested in the outcome - go analog, go digital, go with what the hell you want - but, if you must compare/test and publish your findings, do it properly and stop wasting my time!
Just a little reminder...digital can reproduce a recording to 100%, analog can not. I'm listening to music via every shit I own...turntable, tuner, CD player, cassette deck (all Revox...not, that it matters), laptop-DAC, Philips GoGear "walkman", phone, FLAC, mp3 (320kbps, VBR V0. etc)...and enjoy all of them - go figure.
