Which Nakamichi to choose?


I have the opportunity to get a very good Nak Cassettedeck 1 or a DR-2. Which one would you choose? And why?
Thanks for giving a newbie some valuable advice.

@terry9 I have never been fortunate enough to use a CR-7a my decks were a DR-2 and a DR-10. I have no doubt a really high end deck would be a different experience.
@jond , I agree with you; I tried it and decided against using it. I think everybody back in the day tried it and came to the same conclusion.
  I still have tapes that I recorded with "Dolby On."
It's true that the many cassette decks suffered high frequency loss using Dolby Noise Reduction, however this was not an issue with the better Naks. I have owned a Dragon, CR-7a, 670ZX with NR-200 Dolby unit, RX-303, 581Z, and still have my original 582. None had a high frequency loss using Dolby.

@terry9 , the CR-7a must be like "studio quality," (I realise we're talking cassettes).

Would Dolby B on a stock CR-7 effectively reduce noise w/o limiting sonics?
Thanks for that info, @tls49 . I still love analogue tape and have considered a used Nak to archive vinyl.

Was Dolby C of any use on the Naks?
