Nikko NR-1000 (c. 1981–82)
The record on the Nikko NR-1000 is thin, but the period sources that do exist agree. This was Nikko's early-1980s push into digitally tuned receivers. Nikko's own advertising portrayed the NR-1000 as a flagship piece in the tradition of its acclaimed Professional Series. High-Fidelity-Trade-News (March 1981, p.75) and HiFI-Stereo (1982, p.33) both carried the same campaign. The ads pushed quartz-synthesized digital tuning, six AM and six FM presets plus an Auto-Tune function, a DC power amplifier for wide frequency response, and a two-color LED power level display.
The September 1981 issue of HiFI-Stereo (p.50) actually put the NR-1000 on the test bench. The amplifier clipped at 81 watts per channel into 8 ohms at 1 kHz. That works out to a 0.96 dB IHF clipping-headroom rating over the 65-watt reference. The review also described the front panel: small rectangular buttons for tone defeat, subsonic filter, stereo/mono, and loudness. The digitally synthesized FM/AM tuning had six preset memory channels per band. The original's price and full spec sheet aren't documented in the archive's records.
By June 1985 a follow-on NR-1000B was being offered. HiFI-Stereo (June 1985, p.15) listed it at $479, weighing under 20 pounds and measuring 17¼ × 4¼ × 13¾ inches.
