Description
This is a used, functional, NAD 4020A as can be seen in the video of this tuner located at youtube.com/watch?v=86Wn3KuO8WI . The tuner is working well, however was designed in a time where the FM band was not nearly as crowded as it is at present. Accordingly, careful tuning is necessary to get the best from it. AM reception is also working properly and both FM and AM sound absolutely spectacular. The tonality and separation from a good signal are striking in that the tuner gets out of its own way and simply conveys the best of whats available from a given station. Some stations, obviously, give more than others, so YMMV. It truly shines on jazz, classical, and classic/album rock. One review stated thus: The NAD 4020A is a rationally designed and built, at moderate price, AM/FM tuner, whose performance in most locations and with most broadcasts is audibly identical to that of many more expensive and elaborate tuners. The 4020s quality of sound is limited only by the quality of the transmitted broadcast.Recent dramatic advances in FM tuner circuitry, particularly in the development of inexpensive but high-performance building block circuit modules, have been incorporated in the 4020A to provide excellent sound at reasonable price. Such crucial design parameters as sensitivity, low distortion and wide stereo separation have been given priority over the inclusion of costly superfluous features and esoteric circuitry whose benefits are totally inaudible except in rxtreme reception conditions. But no compromises whatsoever have been made in those performance areas which relate directly to the 4020s listening quality in normal and even somewhat difficult reception locations. It is important to maintain wide stereo separation at low and high frequencies as well as the commonly specified 1 kHz midrange point. In the 4020A phase shift of the composite signal is minimised in order to preserve full low-frequency separation, and a special NAD phase-compensated crosstalk cancellation circuit increases high-frequency separation and minimises any residual distortion.Instead of a costly and fragile moving-coil tuning meter the 4020A has a set of three LED indicator lights which form a remarkably simple and accurate meter. Either of two amber LEDs illuminates when the 4020A is mistuned to either side of a station frequency, and a green LED illuminates when the station is optimally tuned for minimum distortion 9within 0,025 MHz). The brightness of the green tuning LED indicates the signal strength, when it is dim the station is too weak for optimum reception. For the music lover seeking uncompromised performance for a modest investment, the NAD 4020A is the logical choice. There are more costly tuners available, some of which have more impressive specifications,, but very few sound better in everyday use.
