I voted B. It was the heaviest to me and the clearest in the music and vocals. Regardless, it was the most enjoyable.
 
Please give the results when this is over because I want to know.

One does not simply successfully ABX q10 and lossless. Four hundred and sixty six kilobits!

Total: 13/16 (1.1%)

I wouldn't call that a pass, but at least I have a ticket to submit my opinion.

I couldn't do AB or BC, so I'm gonna go out on a limb and say A is the mp3, and either B or C is the lossless, but I'm leaning towards C because I recall I couldn't ABX v0 vs q9 way back.
 
But I'm sure I'm way off, what a vicious test.

Did you manage to get a decent ABX result without unplugging your sats? ahahah

Nobody else? Certainly more difficult than BLIND TEST: Lossless vs. MP3 320 owing to the fact that the sample was selected from a more conventionally mastered release as opposed to the more dynamic DCC and unlimited HDtracks versions.

Although the files don't download, I can tell you that even with stock earbuds, the difference between a 10meg and a 100meg file of the same material is too obvious. So what's the point?
