Ive tried it a few times, mainly cause i thought the sound quality would be better than the vinyl version of a song, but I haven't really seen any great difference. My vinyl usage is also partly because even if you get a cd compliation or reissue, alot of the best shit is hidden in dusty grooves, and a mate schooled me that with the proper set up vinyl sounds better.
But i think its generational too. i know one young producer (over here in Sydney) the dude is fresh, he just grabs any cd's (random shit) and grabs sounds and samples of them and flips them into some heavy killer tracks. He aint a crate digger, or dj, has fuck all equiptment, but is more prolific, and original than many tradional styled producers.
And with serrato, cdj's,cdr's, mp3 its awhole new set of audio sources we didnt really have when i got into it, so maybe kids will flipp that shit in different ways. I heard of cats making beats of old viedo game sounds and gameboys and shit nowadays....
on a side note, I heard of kids downloading mp3 of breaks and using them to make tracks. What do ppl. think on that?
