[QUOTE="DACMan1, post: 1049888, member: 112"] Seems the test is between Apple AAC 256kbps and flac. But both files are lossless flac files, so there really is no way of telling if they really did compress the one. And the "compressed" files are extraordinarily good. I subtracted the files and the peaks are in the -30dB range. I am going to try my own test later to see if I can get remotely the same results. Edit: Seems that something is indeed fishy. I am not getting anywhere near the same results compressing their "lossless" version with AAC 256kbps - I get the very obvious high-frequency cutoff. [/QUOTE]
