Nakamichi were known to be the best tape deck in the world. Period.
If you can find out one at a good price, with the head not worned out, grab it!
If not (it is likely), I do remember that Teac did very good decks as well; aim for the higher models, of course.
If your tapes are original, they most probably have Dolby B; best 80s deck have also Dolby C, and even Dolby S (rarely DBX, too); they should be turned on only with tapes recorded with the same kind of noise reduction to get the best result, even if there was one that would be beneficial also with tapes recorded without NR - can’t remember which one, you must do your homeworks here! 😃
