hi, a friend asked me if he could achieve dtshd or dolby hd on his older yamaha amp... i told him that he could get a bluray player with multi-channel analogue outs and connect those to his amp's multi channel in's & that the bluray player would do the decoding and the amp just doing the amplification thus achieving the hd sound he wants. have i given him correct info on this? as he went into a local dealer and they said that i had given him incorrect information & that it wouldnt work using the multichannel outs & ins... can someone help on this matter please?
