Hi, Just ordered a Velodyne sub from Uncle Eric and I need to connect it up to my amp. I use a 'free' interconnect with my current sub but I'd obviously like something better for my new toy. I just so happen to have a QED digital co-ax cable that I no longer use. This is long enough for my needs (4M I think). Can this be used? I don't know the model number but it came from RS and was about £40. The 2m version costs about £20. If it is not suitable, what should I get? Many Thanks, Richard.
