New test coming tonight. I will post a new thread for it.
Oh this looks like fun!
Here, I'll give you two files if you wanna try. Both are WAV so it completely rules out file size bias.
I can just BARELY pick these myself, my equipment is entry-level stuff and my ears not so trained...

Song is Last of Days by A Fine Frenzy.
One is lossless, the other is mp3 165kbps VBR.
Temporarily not available?

Failed miserably, even though I know which is which (I cheated) I could not DBT them in FooBar 2K. Not music I am familiar with or particularly like but that is no excuse, I could not to pick them out, 52 year old ears and improved codecs I guess ....ho hum. The biggest differences are in the higher octaves where my hearing is age-related poor and at ~ 30 seconds there is a segment where the mp3 high frequency roll-off is more pronounced as the lossless maintains the higher frequencies at relatively high amplitudes.
Interesting, thanks for that.
However, rather than folks opining it is def A or it is def B put them both through the ABX comparator in FooBar 2k and score how often /20 you correctly identify A = X or A = Y , that is much stronger evidence of detection, mine was a random 50% with two options correctly guessing once is not great evidence...

For the flac comparision files in OPs post I'd say B is lossless (or then both are the same in case the OP decided to be a person to fool people into thinking they can hear something they aren't ), haven't checked comments to see which is which so don't know about the answer, definitely not easy for this track if they really are of different quality. Usually I find picking out 192kbps vs 320kbps mp3 easier even. lol
