- Comparisons between Dolby S and DCC and MD must take the particular
- decks and/or electronics into consideration. While these NR &
- compresssion techniques will tend to have certain effects, the other
- sonic attributes of particular cassette decks or MD/DCC decks will
- possibly make a much larger difference.
-
- One big problem, which I've had with all but the ultra expensive cassette
- decks, is flutter and speed stability in general. Dobly S isn't going
- to make a wit of difference there. Also, the quality of the A/D and
- D/A process is quite audible, and relates to perceived sonic quality,
- even in data-reduced formats like MD and DCC. The digital formats,
- compressed or not, do lack problems with speed stability.
-
- By the way, this NOT an endorsement of DCC and MD. I am loath to even
- talk about these formats seriously at this point, since they are techni-
- cally in a negative direction -- mass marketing of sonic compromise. If
- I could, I would encourage avoiding these formats. Hopefully, the
- competing formats will kill each other in the market via the resulting
- confusion and lack of consumer confidence. Whatever, I'm not buying.
-
- I do think lossless or nearly lossless compression approaches are worth
- looking into, but the approaches used in DCC and MD formats don't qualify.
