Hi, I've got separate hifi amp and AV receiver which I use with the same pair of front speakers. Does anyone know of a switchbox that will allow the connection of both amps to the one set of speakers? I've tried using the amp for the front channels by connecting with the reciever pre outs but I couldn't get rid of an earth loop and it sort of unbalanced the sound anyway. I don't use the hifi half as much as I used to as I can't be bothered to swap over the cables. Any ideas gratefully received. Andy.
