My Sony ns 300 DVD player outputs dd and dts though I don't think it has a decoder on it. I'm weighing up sub £200 amps and am interested in the pioneer sc301 -- it's doesn't have 5.1 analogue. can someone please explain why I need 5.1 if I've got DD and DTS. What's the benefit of having 5.1 -- future proofing? -- or do I need it to make the most of my current dvd player? Yours, very confused.
