Hope someone can help me on this one. I have one set of front speakers (Mirage OM-5) and two A/V systems. My main system, which is too complicated for my family to use and a Pioneer reciever, which my family uses for normal TV/DVD viewing. What I currently do is have the speaker cables for the Pioneer banana-plugged into the speakers for their use and I then switch cables and plug the speaker wires from my Adcom 555II into the speakers whenever I want to listen to my system. This works, but is a pain. I would like to find a switcher that I can use to feed either speaker output into the speakers. Does anyone know of such a beast? It would have to be capable of handling 300 watts without degrading the sound quality. The only one I have been able to find is made by Niles Audio, but it doesn't look like it's a top quality unit. Or is there a better way to accomplish the same end? I also thought of plugging one set of banana plugs into the other set of bananas so both units are connected at the same time, since neither amp would ever be on at the same time, but I was worried that it might somehow feed back into the amp that was not in use and damage it, I have no idea if that would be a problem, but am not knowledgeable enough to try it - I would hate to fry an amp or speakers experimenting. I'd sure appreicate some advice. Thanks.
