Hi - I was just wondering if anyone can help - I have a run of speaker cable that I currently use to bi-amp my speakers - I have just bought some new cable so want to use my old stuff in a second system however it only has one set of speakers terminals at the amp end - the speaker cable has terminated ban plugs which I do not want to cut off - does anyone know of a gadget that connect two banana plugs to one set of speaker terminals at the amp end - my speakers are bi-wirable so no problem at that end? Thanks
