Have just been to richer sounds enquiring about the Pioneer DVD656A. Asked if there were any other players with similar features most importantly on board 5.1 decoding and dts. The only one he mentioned was an accustic DVD451 for about £90 saying that i wouldnt really notice the difference in sound or picture quality. Does this guy know what he's talking about or is he just a knowledgeless temp?? Im sure richer sounds must sell other 5.1 decoding machines???
