Yamaha 1110U (Late 1980s)

Period reviews identify the Yamaha 1110U as the CDX-1110U, Yamaha's flagship compact disc player of the late 1980s. Audio (September 1988, p.103) introduced it as a design that combined advanced technology seen before with ideas appearing for the first time. That was a moment when several CD-player makers were moving to true 18-bit D/A converters in their top models.

The same magazine's September coverage (p.104) highlighted the CDX-1110U's eight-times oversampling. It let Yamaha keep the analog filtering very mild, or skip it entirely. A later Audio equipment profile (December 1989, p.104) listed the manufacturer's figures: frequency response 2 Hz to 20 kHz ±0.3 dB, de-emphasis equalization ±0.3 dB, THD plus noise below 0.003%, and a weight of 35 lb 3 oz. The price was $1,499. HiFI-Stereo (January 1989, p.76) included the player in a reference system and cited a dynamic range of 100 dB and THD plus noise at 1 kHz of 0.002%. High Fidelity (October 1988, p.44) also covered the machine and concentrated on its resampling scheme.

Beyond those period reviews, the record is thin. No production-run details, sales history, or service information have surfaced in the available documentation.
