agreed and approved!
I know some people say it's the same thing if it's 320kbs mp3 or wav. But to think of it, wav is ~1400kbs so it actually holds over four times more info than 320kbs file.
But indeed like Rino said, some smaller parties e.g. home party with friends, are sometimes quite okay with mp3s too.
Oh I picked CD in the poll. I really dislike scratchy vinyl sound, with the expection of old jazz records
