Hi there, A year or so ago, my wife purchased a sony DAV FX-500 for me as a gift. Sony DAV-FX500 XM Ready, 5-disc DVD home theater system with digital video output and upconversion at Crutchfield.com I've been just fine with it for a while, but I've already run out of inputs. I wanted to purchase a receiver, such as Sony STR-DG720. Sony STR-DG720 Home theater receiver with HDMI switching at Crutchfield.com What I want to do here is obviously save some $$ and not purchase all new speakers. I'd like to "recycle" the speakers, however the DAV system has special connectors. Can I remove the end, strip the wire and plug into the new receiver? If so, is there something I need to watch out for? Also, for the sub, it has the same connector, on the DG720, the connector looks different. I guess I might need to change the sub also. Any ideas would be greatly appreciated. Thanks!
