These are all mathematically lossless codecs. They theoretically should sound identical when using the same hardware and playback software. I don't believe I could conduct double blind or any other subjective test which would prove beyond any doubt that there are any differences between the options aurally.
-> When something is mathematically lossless, proving the encoding / decoding algorithmes is the only way to go. Double Blind, Subjective??? I'm really sorry I read the whole thing, I want a refund for my time!
