You say this: How can he be "wrong" when he's speaking about his observations? And how can anything you've said about mp3 apply to his being "wrong" when he didn't use that codec (he used AAC)? Then you say: ...which is, if I'm allowed to be as binary as you, an inaccurate explanation of how MPEG coding works. Note the emphasized word above. OK, Mr. Black and White, now please explain (with minimal verbosity...if possible) how Bigshot was able to repeatedly recode without observable quality loss. NO, it's not. NO visual analogies...again...please!!! Again, if I'm permitted to be as binary as you are, your visual analogies...all of them...are wrong. Copiers don't use perceptual coding!!!! They are just lossy. PLEASE let's not spend time trying to defend your pointless analogies.
