Considering 1 of the 2 options below. Opinions please assuming I spend the same budget either way. 1/ Conversion of my existing Yammy DSP A-970 amp to accept (via d-con.) signal from a seperate DD/DTS decoder. The Yammy DSP E492 has been suggested. Cost of conv. £250 c/w cable. Cost of DSP E492 unknown. 2/ Buying a new A/V amp/rec. Don't really want to compromise by buying DVD with onboard decoder. That'll be coming at Xmas! Will option 1 make things a little more flexible for future upgrades while ensuring best quality ? Am I making any novice like errors?
