Re: What's with all the hate for vinyl?
"CD decks for scratching exist. Whether these are up to what you describe, not sure."
Yeah I know they exist but it's only ever going to produce a synthesized approximation of the real scratching. I'm not saying people will necessarily be able to tell the difference. Whether it's an acceptable replacement would be a similar sort of question as asking someone whether a synthesized guitar sound would be acceptable in place of a recording of the real instrument. It's a matter of personal preference.
I am no expert on scratching but I'd imagine there could be certain effects or subtleties that some people could achieve with vinyl that they couldn't on one of these CD decks.
