Hello there, I am hoping someone out there can give me some information on the compatibility of amplifiers. I have a PANASONIC 5.1 surround sound system, which is over 5 years old. I would like to update the amplifier of the sound system, to a more up to date model. However amplifiers of other makes, are far more popular than Panasonic, so I was considering purchasing a SONY. Will the cable for connecting the amplifier to the sub-whoofer be the same on the Sony, as it is on the PANASONIC. It is a flat plug, one and a quarter inches wide, on each end of the cable, and plugs into the relevant socket on the apparatus. It would be pointless buying a SONY if it is not compatible with my Panasonic speakers. Many thanks to all who offer advice.
