Hi, I've been offered a 2nd-hand Sony TA-VE215 (or sometimes known as HTK215) home cinema system. Is this a reasonable system for a small lounge?? Can I connect a PS3 & Sky Plus to it via Optical cable?? Can I extend the rear speaker wires / buy VERY long extended Sony wires?? (As I'm told Sony have their own connectors?) Grateful for any help!
