Sansui X-901
The designation "X-901" shows up in late-1980s Sansui literature on two related components from the company's "Vintage" series: the AU-X901 integrated amplifier and the CD-X901 CD player. The surviving record never says which of the two the bare model number points to, so both are covered here.
Sansui's own advertising in Audio (August 1987, p.30) introduced Vintage as a collection created for the discriminating listener. The performance story started inside the AU-X901 - an integrated amplifier designed to deliver sound previously associated only with separates. Follow-up ads in the same campaign (September and November 1987) credited the amp with Sansui's exclusive "Alpha X-Balanced" technology. The AU-X901 later appeared in HiFI-Stereo's 1989 integrated-amplifier survey (p.82). The listing shows Alpha X-Balanced circuitry, a direct-balanced input for Sansui CD players, an independent record selector, dimensions of 17 × 3 × 12 inches, a weight of 20 lb, and a 5350 price.
The CD-X901 got the stronger praise at the time. Audio (January 1988, p.107) remarked that after several years of concentrating on rack systems, Sansui had returned to designing components reminiscent of the high-end Sansui of old. The reviewer counted the CD-X901 among the finest-looking and best-sounding players he had tested, the equal of some of the most highly regarded CD machines available. HiFI-Stereo's test report (January 1988, p.34) described a player that could feed its digital playback signal, before conversion to analog, through a standard phono jack to an outboard processor. It also noted a 10-second intro-scan function, a large amber front-panel status display, and a "music calendar" readout of selected track numbers.
Beyond these period mentions, the record is thin. Full engineering details, production years, and service documentation for either model have not turned up in the Archive's search. If you own an AU-X901 or CD-X901 and can fill in the blanks - sound character, common quirks, manuals - the Archive would like to hear from you.
