The amp in question is the Yamaha DSP A2. The reason i ask is i need an RF demodulator for my Pioneer CLD-D925 laserdisc player. Now a demodulator on its own can fetch some pretty high prices on ebay when they turn up. But ive seen mint DSP A2's go for about £200-£250. Plus i would not have a seperate box that way to. I currently own a Yamaha DSP AX620 is it worth changing from a sound point of veiw? Seeing as things do move on. Baring in mind im not bothered about 6.1 Dts ES and Dolby Digital EX. Is it still worth doing?
