I have just upgraded my amp to a model that has d/d and dts decoders onboard, have connected the dvd and amp by a digital lead, previously I had the dvd connected to the amp by phonos as the amp only had the 6ch inputs and no decoders, but the dvd player did. The sound I am experiencing now is dreadful, what has happened? I have read lots about digital leads, Optical and coaxial, which is best, and a few posts about jitter and dacs etc. So are analogue connections better than digital ones? I understand that dac stands for "Digital to Analogue Converter" but when connected by phonos are the dacs not used? If not, then I can understand why the analogue sounds better, a direct signal with no conversion necessary and that's why the sound reproduced from equipment using digital leads and dacs sound infearior. What about jitter, have read that jitter can be present in the amp, dvd player and digital leads, coaxial being the worse offender, Is jitter only a problem when some sort of conversion is going on? So by connecting by phonos does this cancel out the possibility of having jitter present in the sound side of things? I will be connecting my equipment back by phonos, I thought that digital was the way to go, but having listened to what it has done to my relatively modest system no thanks.
