Nakamichi CR-30 (1988–1989)
The Nakamichi CR-30 is a three-head cassette deck from the tail end of Nakamichi's analog era, built in Japan around 1988-1989. It was the last full-featured model in the CR series. Period Japanese sources give a list price of ¥100,000, though a U.S. figure of $795 has also been cited. The CR-30 shared its service manual with the CR-3, CR-3A, and CR-3E. The family resemblance is clear. This is a deck built on Nakamichi's traditional discrete three-head approach, not the auto-reversing complexity of some later models.
The headline feature is the fully independent discrete three-head system. Nakamichi argued it avoided the high-frequency loss caused by magnetic azimuth shift in combination heads. The record and playback heads are separate Crystalloy units with a self-polishing contour, which the company claimed kept like-new performance for over 10,000 hours. The transport uses a closed-loop dual capstan arrangement. Two capstans turn at slightly different speeds to hold tape tension without the tape pads or guides that could add modulation noise. Nakamichi also used a frequency-distributed transport design to avoid overlapping flutter periods, and the whole mechanism was built for silence.
The electronics follow the usual Nakamichi house approach: a multi-regulated power supply with high-speed discrete regulators, a dual-mono amplifier board configuration, and gold-plated input/output terminals. Dolby B and C noise reduction are on board, along with an independent equalizer switch, an output volume control, a tape slack prevention mechanism, and an acoustic insulator to cut external vibration. A system remote terminal and headphone jack are fitted. The RM-5 remote was sold separately for ¥6,000.
The period material makes the manufacturing discipline the most striking part of the CR-30. Nakamichi claimed roughly thirty internal adjustment points. That includes six bias trim pots for left and right channels across three tape positions, where a typical deck might have only one per channel. Every unit also got a 56-item characteristic measurement before shipment, and only decks that met every specification were released.
Rated performance: frequency response of 20 Hz to 20 kHz ±3 dB at -20 dB recording level across Type I, II, and IV tapes; wow and flutter of 0.035% or less Wrms; signal-to-noise of 72 dB or better with Dolby C on Type IV tape; and total harmonic distortion of 0.5% or less (EIAJ). The deck measures 430 × 100 × 265 mm and weighs approximately 5.8 kg.
Documentation on the CR-30's real-world reception is thin. No substantive period reviews have surfaced in the archive, and most contemporary references are sales listings and owner's manuals. The record does show a Nakamichi deck with the brand's usual heavy calibration, aimed at listeners who valued recording accuracy over convenience features.
