Hi, I have a Mission Cinema6 speaker pack and a Marantz SR4200. what is the best cable for connecting the amp to the Sub? I am currently using a Ixos 118-AV but this is only 1M. Also my sub has 2 inputs and I'm using a cheap Y connector to connect to the amp. will I be loosing quality? where can I get a better quality Y connector? I'm using QED Bronze Special Edition Speaker Cable for my other speakers. Is this a good choice? Also if I wanted to upgrade my speaker what would be the best route. I am thinking about replacing the Centre speaker with another from the Mission range. One last question I want to connect my computer Soundcard to my AMP. I'll make the cable myself. I was thinking of buying about 15m of Speaker cable put 2 jacks to connect to the L&R of the sound card and phono connectors on the other end to connect to the AMP. Where can I get these connectors? Any ideas?
