This may be a fairly basic question, but I couldn't find it in the faq... Other than convenience and looks, is there an advantage to terminating speaker cables? It just looks like another layer that the signal needs to go through. More importantly, it also adds significantly to the cost of mid-range speaker cables. Do some cables/speakers/receivers "require" termination? For example, the QED X-Tube XT-400 (example only, haven't bought it) looks rather thick and has a strange design, can I still pull off the outer layer and plug the bare wires into the amp/speaker anyway?
