i got a little lost reading that so im just going to take a stab here and try help ya out. beatport should be selling wavs of all its files. if not then thats a bit slack. you can check other sites out like trackit down etc or like you said, hit up iTunes. theres nothing wrong with their conversion format but some people got it in their head that because it doesnt say 320kbps mp3 then it must be bad. i use iTunes files and 320mp3's and there isnt a lot of difference. if you're after something that has been released on iTunes and not on beatport its usually some legal region thing but theres a massive confusion to it. some tunes are released on different labels for different regions because it may not be allowed to sell in one particular place (i dont know how it works but its bullshit) so if you cant find what you're looking for on beatport then shoot over to iTunes and it will probably be there. its real strange but thats how it is lol
