- This is probably a FAQ, but if nobody ever-asked the question, it wouldn't be
- a FAQ, would it...?
-
- I've been thinking of replacing my Denon CD player (I think the model number is
- DCD 1200 Mark II) with a LD player which would also of course have a CD player
- built-in. I've just begun looking at LD players, so I'm pig-ignorant about them,
- so, here come the questions.
-
- I want an LD player with a fiber output, so I can later purchase an outboard
- DAC. Presuming that I do take this step, do all LD (and all CD players for
- that matter) players spit-out the same optical data for a given disc? In other
- words, can a player manufacturer screw-up the digital data coming off of the
- disc? (Error correcting comes to mind here). If the only "audible" differences
- between players comes from the DAC portion (plus power supplies, etc), then with
- an outboard DAC, all CD/LD players should sound identical. Is this a true
- statement?
-
- What is the resolution of the LD medium? I've seen Pioneer LD players with 425 lines
- of resolution, do any other players do better, or is this number a function of
- the medium itself? The best S/N ratio I've seen is 50 dB, is this also a function
- of the medium?
-
- Do any LD players perform picture enhancement, colour blooming removal, or any
- other DSP type functions on the video image?
-
- I've looked briefly at the Pioneer 701, can anyone make any comments on this
- unit, or recommend other above-average LD players?
-
- Thanks for any feedback or comments. If I've missed anyother important questions,
- please let me know.
