OK I have a Sony DAV S300 HTIB system. It works fine and its good for what I use it for, but I really want to be able to hook up my Xbox for surround sound. I therefore require a DVD unit with an optical input, which typically my unit does not have. Because I already have the speakers, I'm ideally looking for another Sony unit (as the speakers will slot straight in without messing around with the connecters), but it must have a built in amplifier. Of course, only the HTIB systems have a built-in amplifier, and I don't want to spend money on a whole new system just to get one optical input! I've looked on eBay for prtial packages but to no avail I've thought of getting an external AV receiver with an amplifier, which would have loads of inputs, but I don't want to spend too much as I'm moving house in 2 days!!! How hard is it to cut off the Sony-shaped connectors on my speaker wires to fit in another make of DVD player? What modles are there with a built-in amp that would be suitable? If an external amp is the nest way to go, what should I look for? There's juast so many different models to wade through and its giving me a headache - someone save me! Cheers!
