Generally I cannot tell MP3 VBR 0 from lossless. However I was able to DBT them on one specific track to a P < 0.05 level (14/17 or something like that) , on the track in question the original file was heavily saturated , peaking frequently at 0db and the endoding appeared to add a small extra amount of distortion, the telling them apart was really hard and I had to focus on one small (5 second ) segment and go back and forwards between the two of them many many times. Nevertheless I managed it. In casual listening I would have been unable to tell them apart only with extreme concentration and mind-numbing repetition and only with one tricky sample...

^Wow alright man thanks for sharing
I really should AB some files one day. All of the current stuff I get now is ripped to FLAC and used so I'm probably just gonna wait until I'm forced to convert and see what happens

I know you probably just mistyped, but please know the difference between AB and ABX testing. The former is not useful in this context.

I think you'll find if you're ABX testing a random song for the first time, you'll probably even have trouble comparing 128 vs flac. You will be surprised how hard you need to listen, and how much experience it takes knowing where to listen. There are some rare files where it is very obvious, but on the whole lossy encodings are very good and you will find yourself confused.
