first of all is it really worth it I do have the Xtra cables lying around...second the receiver has bananer plugs but im not using them i just loosen the screw cap and slide the wire in....should I A: buy banana plugs or can i just put the 2 cable in the hole with the 1rst one. I thought 2 cables using the same out would reduce the power flow or quality. I would only do the fronts and not the rears. not sure if my centre has the Xtra binding posts.

Thanks
