Hi Darren, Yeah, let's talk about this... 1. Indeed the metal tune "Keine Zeit" was the track that would likely sound "most different". Lots of noise and other stuff for the MP3 to encode :-). But remember, the MP3 was also the "most preferred" over the original FLAC! So yes, I suppose if one had lots of hard-to-encode hard rock / metal albums, maybe one would notice a difference... But one might also *prefer* the sound of MP3 at 320kbps. Remember that MP3 is indeed not perfect of course! There are test tracks like keys rattling and such used to fine tune the psychoacoustics at various bitrates. 2. Sure. Stuff like coaxial digital cables that pick up noise can influence the DAC output in extreme cases (eg. poor shielding). But I don't think I've demonstrated anything else unusual...
