Which Nakamichi to choose?

 Let’s not forget that Nakamichi decks even now hold a good value if serviced by the previous owner. Some of the models mentioned in this thread are rare and very expensive to buy if well maintained by previous owner.  If you want a good Nak deck which records good and sounds good for playback consider the BX-300. It does not have the remotely controlled Azimuth adjustment like CR-7A but it sounds very close to it and its specs are very similar to CR-7A. You can find it more easily in good condition for $200-$300. 

My problem is that when I use Dolby B or C while recording on a Nak, it does not sound the same on Aiwa HS-PC20 CassetteBoy in my car with Dolby. So I started recording at very high recording levels on my Nak without Dolby and now I do not have any loss of high frequencies and there’s no distortion.  Since the signal-to- noise ratio is so high I don’t hear the hiss.
