Nakamichi CR-7E
The CR-7E has an automatic bias, equalisation and azimuth set up system; press the button and it goes through a ten second cycle of auto alignment to the tape in question, and from then on you know you're getting the best out of the cassette. There's also a user-adjustable azimuth control one twiddle will change it (and the FL display switches over to a graphical representation) to give perfect playback on any tape recorded on any other deck (often with slightly different azimuth due to misalignment). These are the Nak's only two concessions to gadgetry, and you couldn't get any more useful than these.
