I am connecting a tv, dvd player, dts amp and dts surround speaker system. I am happy enough with buying the relevant speaker cable but what other cables do I need? My Canton speaker manual says the active subwoofer needs a cinch cable. What is that? Is that on top of connecting the amp to subwoofer by two phono plugs? Basically I bought the amp and speakers separately and this is my first home cinema setup. The no. of connections on the back of the amp (TEac ag10) are bewildering! I would like to use best quality connections. I notice the amp has several video connectors - do they need to be used? I figured it was only needed for audio.
