He's asking because of this one for sale (not mine):
DASC For Sale
I heard that the DASC is also louder than a DAO. I've never played on a DASC, but only a Ransai and a DAO. The guy is trying to sell a used DASC for $250 which is not a good deal when again a DAO can be had with shipping for around $300. If he was going to sell for maybe $175 or so then it could be a good alternative. Of course the DAO also looks a lot better, so if you have the cash go for the DAO.
