Thanks for the reply --
I didn't explain the context of my post very much, so I will try now --
What I was getting at was that if you're doing a re-mastering job on some pop material from the 70's - 90's that was tracked and mixed to analog, 1/4" or 1/2" or whatever, many (not all) of these tapes used some sort of NR. (Interestingly, when Mobile Fidelity did their remasters, their dolby cards needed to be special, to adjust for the fact that they played their tapes back at half-speed when mastering.) So anyway, you've probably got a great tape deck, some other killer gear (for vinyl or some sort of digital mastering), yet if the tape uses NR, you have to use the appropriate NR card when you play back the tape. My question really is, how *good* are those cards? I understand the general point that says "no NR is transparent" and indeed I would not use any if I were making a high quality recording on 1" or even 1/2". But if you have a tape that requires NR for playback, you have to use it. Since my thought is that these cards are probably a "weak link" in the process, considering the wonderful gear and care that is taken in the best mastering studios, I am wondering whether or not these cards could be improved upon, perhaps through use of discrete high-quality components, rather than what I bet is in them.... crappy little IC chips.
what do you think?
