but does it sound better on 12" or 10"?

As far as Serato goes I think the sound quality has something to do with audio box it comes with. Can you tell the difference between a serato 12" and a serato cd when listening to dubstep?

on one of these systems!

12" vinyl
10" vinyl
12" serato vinyl
CD
Ipod

Letsssss goooooooooooooooooo!!!!!!!!!!!!!!!!!!!
