Yamaha DP-U50
I was wondering does this thing also act as an amplifier?
and is it good?
I saw a picture of someone with this setup with a pair of swans m200 + some subwoofer + grado sr80 and it looks sweet.

So i decided to look for this on Amazon.com and i found this store (consumer depot) that sells it for $79, and the price range is so wide , im not sure if its trust worthy.
Has anyone gotten anything from there?
