Seemed like a good price on this

that looks exactly like the one I had, and if it is the same one, it is a good price. Much less than I paid/sold mine.
Yes, it's exactly the same as mine too. It's a really nice sounding amp, I paid close to twice that at a local shop for it new about 2.5 years ago.
Can this be used to bi-amp a system since it is an integrated?
it has outs that are labeled "subwoofer" which I have read can be used as preamp outs. I don't know if this is true or not.
