CD players
Just to note a few things, more for clarification than anything else (maybe in partial defense of Zeke):

Zeke...
Here's some MAJOR points I made that you didn't address...
1: The converters on a commercial deck suck when compared to a pro-quality unit.... that's undeniable and crucial to the final product.
Well ... maybe. I doubt that they're a lot different from a "prosumer," or at best "low end" pro, deck (which is I think where the Tascam unit would fall on the spectrum ... I don't mean this a slam: I
like Tascam gear generally). They may well both use the same chip. If you want to get a real "pro" setup, you'd probably be using an outboard converter like an Apogee or something ... or if you're a cheap (clever?) pro, maybe a Symetrix 620.
2: A commercial deck cannot "dither" a 24-bit recording down to 16-bits... it truncates the recording. Do you even understand what that means? It means that bits get tossed and the recording loses a significant amount of clarity when it goes on disc. Why would you want to snuff the life out of your digital recordings like that?
I don't know that dithering is that big an issue. If you're running a
digital input into the CD recorder, and what you're inputting has a higher word length, it makes a bit of difference. Of course, if that's what you're doing, you don't care about the AD converter in the CD recorder, which was point 1. Also, if that's what you're doing, there's a fairly good chance that whatever is producing the digital signal that you're running into the CD recorder (an outboard converter, perhaps?) will dither to 16 bits anyway.
On the other hand, if the suggestion is that a 16-bit converter that reads 24-bits, then dithers to 16 is better than a converter that just reads 16-bits, I suppose there's a marginal difference. This is really just a slightly more specific take on point 1, though.
Whether dithering adds "clarity" -- or failure to dither will "snuff out the life" of your recordings -- is perhaps debatable. After all, dithering is the addition of noise in exchange for some benefit in audibility of very low-level information.
3: The meters are extremely accurate on a "pro" deck, and the meters on a commercial deck are NOT. This is important when you're trying to get the recording to the proper level. (Red Book Standard)
I don't really know the accuracy of the various meters. You might be using meters on your mixdown deck, or whatever. I agree that meters are quite useful if you want to use as much resolution as you have without any digitals "overs." I'm not so sure the Red Book standard requires a particular level.
4: Commercial decks don't have the ability to boost or cut the db level when recording straight in with S/PDIF cable. This can be necessary when you just can't get the levels high enough on the original source of the recording (...the stand-alone recorder). Sometimes you need to bring that level up with the CD recorder itself.
Actually, I think some Philips units do this, but I haven't actually used one, so I'm not sure. I'm not so sure I particularly see the huge value is raising the level of a digital input, at least when you're just duping a stereo track (and I definitely don't see the value of
cutting it). You
can't produce any more resolution -- nor increase the S/N ratio -- just by bumping up a digital signal.
On second thought, I guess boosting (and cutting) might be useful in doing some sort of quasi-mastering, so you can put together a series of cuts with matching levels. I don't think I'd do mastering with a consumer deck (or the Tascam CDR deck, either, for that matter).
5: Digital fades are perfect, manual fades are not. There's been times where I did a GREAT manual-mix, only to screw up the manual-fade at the end of the song... that can be extremely frustrating.
I don't know how much I'd pay for a digital fader.
On the cost of CDR thing -- it's really shrunk to not much. I've seen Mitsui "audio-only" CDs in jewel boxes at 79 cents (minimum quantity 11). Actually, I just now looked at another source which is selling audio-only CDs on spindles (200) for 39 cents. You'd have to make a
lot of CDs (a thousand?) to make up the price of a "pro" recorder.
I agree that a consumer CD player would probably not be something you'd want in a "studio" (if by studio, we mean an honest-to-good commercial facility). If you saw a standalone CD recorder there, it would most likely be a Masterlink, I guess. But it might well be something you'd want in a home recording setup, and "home recording" is at least in the title of this bulletin board. I'm not saying it would be right for everyone. It might well be wrong for the original poster (perhaps more because of SCMS more than the other stuff). But it would be a good choice for some people -- maybe a lot a people.
Two thoughts for the original poster:
- I haven't used a Masterlink myself, so what I think of them is worth about 2 cents at most, but I can note that the feature-set looks pretty nifty and some people who at least seem really to know what they're doing are using them. Apparently the mastering houses now have them, so they've sort of become one of the possible
de facto standard formats for exchanging program material.
- A clever (perhaps too clever) two-step upgrade path might be to get the relatively cheap standalone now, then upgrade by getting a standalone converter at some point. If you can actually put your hands on one, a Symetrix 620 goes for an absurdly low price (like $200 or so). And it dithers! (From 20-bits to 16, anyway). And has cool meters! If you use an outboard converter, you're basically turning the standalone into just a drive (and, if your outboard is just a one-way analog->digital, like the Symetrix, a player). This eliminates the converter-quality issue,
and also the SCMS issue.
