Kyocera DA-01 (1983)
A first-generation CD player that weighed more than some amplifiers and cost as much as a used car, and reviewers adored it.
Overview
The DA-01 arrived in April 1983 at $1,050. Kyocera put a gun-metal front panel on it and finished the sides with wood panels, so it read like a receiver or a high-end cassette deck instead of a shiny new digital gadget. It weighs 18½ lbs. (8.4 kg) and measures 18¼ inches wide by 5¼ tall by 12⅝ deep, so it takes up real shelf space. Audio (August 1983, p.71) noted it was "almost as large as an integrated amplifier or a complete receiver," and that a casual observer could easily mistake it for one. Early adopters who wanted their first CD player to feel like serious furniture got what they wanted.
The loading scheme is what separates the DA-01 from everything that came after. There's no tray. A hinged door swings down to expose a narrow slot, and the disc goes in label-outward. The user pushes it all the way down into the door and then closes the door by hand, cassette-deck style. It's a fussy ritual compared to a motorized tray, and it either charms you or drives you up a wall. The transport itself is contact-free, which was the whole point of the format - no stylus, no record wear, no tics or pops.
The DA-01 earned its reputation in the filtering. Kyocera built it with both digital and analog filters in the signal path, and the company marketed that combination heavily as the cure for the "brick-wall" artifacts that plagued early CD playback. Whether the dual-filter approach actually sounded cleaner than a well-implemented single filter is debatable. The spec sheet was impressive for 1983, though: frequency response of 20 Hz to 20 kHz at ±0.5 dB, dynamic range greater than 90 dB, S/N ratio greater than 90 dB, channel separation greater than 90 dB at 1 kHz, and harmonic distortion under 0.005% at 1 kHz. Wow and flutter was listed as unmeasurable, a function of the quartz crystal's tolerance rather than any mechanical limitation. Audio output was 2.0 V rms, and the unit drew 30 watts from a 120 V, 60 Hz supply.
The controls are feather-touch, and the feature set was generous for a first-generation machine. Owners could play the whole disc, repeat a track, scan, pause, skip, advance, and program up to 24 different segments into electronic memory. A ruler-like LED scale tracked the laser's progress across the disc. A separate digital readout showed elapsed time within a track or total time from the start of the disc, toggled by a "Total Time" button. Small LEDs indicated whether total time was displayed, whether programmed selections were playing in order, and whether the Index function was engaged. It's a busy front panel by modern standards, but period advertising leaned hard on the "easier to use than a modern cassette deck" pitch.
Audio (August 1983) ran a full test report on the unit, and the measurements backed up the manufacturer's claims closely. The S/N ratio came in at exactly 97 dB referenced to maximum output, A-weighted, and SMPTE intermodulation distortion measured 0.0065% at 0 dB and 0.04% at −20 dB. The reviewer also flagged the square-wave ringing that the sharp cutoff filter produced, a characteristic shared with other early players, and noted the DA-01's ringing was slightly less pronounced than what some competitors exhibited.
It's not the most famous first-gen CD player, but Audio (August 1983) called it one of the most highly acclaimed of the first generation. The wood side panels and gun-metal face have aged better than the plasticky black boxes that followed, and the swing-down door is a good conversation piece. The mechanical door and the early laser assembly are the parts most likely to need attention, and parts support for a 1983 CD transport is essentially nonexistent.
