Difference between 128 kbps and 320 kbps?

[noidea]

Well, the huge majority of sound engineers and musicians have pretty damaged ears, so that's actually the group of people I would trust least for something like that. But you are right that the difference CAN be minimal(the 128k rip of NEXT LEVEL that leaked actually sounded EXACTLY the same than the first 320k rip of it to me in all songs ecxept Sparkle), however, if you think those millions of people who CAN hear the difference sometimes to always all are liars...do some testing with them, did that for fun with a fiend a few days ago with the same songs in 128k and 320k without me knowing which quality im listening to at the moment...got one wrong, but you probably wont believe me
