NEC CD-830DS
Little is documented about the NEC CD-830DS. The record is essentially one detailed period review. It was a compact disc player tested by Julian Hirsch's Hirsch-Houck Laboratories in Stereo Review (May 1989, p.37). The standout feature noted there was Auto Edit, aimed squarely at cassette dubbing. At the touch of a button it selected tracks from a disc to fit the recording time of a tape cassette, and it could program both sides of a cassette in a single operation.
The same report (p.38) measured the player at 17 inches wide, 12 inches deep, and 4⅜ inches high. THD plus noise at the 0-dB level fell between -93 and -95 dB, with residual noise components between -120 and -130 dB. The largest single spur was a 120-Hz power-supply hum at -100 dB. The player was also run through the error-correction and tracking passages of the Pierre Verany test disc #2. Its display could step through time information for the entire disc via a time button, along with status indications for other control functions.
No production years, original price, or further design details have surfaced. The Stereo Review report is the whole paper trail, but it comes from a reputable lab.
