i have sennheiser hd 212pro, not that they are something special tho.
BUT - what you didnt get is - i dont care whether i download music [buy/get free] or buy CD, its music what matters, not "real" vs "digital dload", and im not talking here in general, im being more specific about wav/losless and not 320kbps, which infact i can get for free so dont feel bothered about buying mp3, cause it indeed lacks some punch in it.
edit: forgot to add, its also attitude, im not pro so i cant say if theres a huge difference between 320 and wav, havent tried, as much as i remember. but i do know that theres a difference, and when i listen to mp3@320 and later on to the same track @wav then ofcourse i can notice differences, but other times i dont care that much, sure, im all for wav/losless, but aint gonna happen in one day tho
