I had three of the four Nakamichi 600 series components; the tapedeck, tuner/preamp, and power amp. The tuner/preamp was especially sweet because it had one of the best sounding tuners I've ever come across. The act of tuning in a staion was a particularly sensual process because the action of the huge tuning dial was so effortlessly smooth. Together, these components were spectacular looking; products of a uniquely Japanese aesthetic and advanced industrial design. Alas, I unloaded all but the cassetted deck due to a variety of pressures.
