Aiwa S-9000
Surviving information on this model is thin.
The XK-S9000 was a full-featured deck with Dolby S, B, and C noise reduction, plus HX Pro. It had dual 18-bit D/A converters with 8× oversampling and a sendust erase head. For digital connections it had both fiber-optic and coaxial digital inputs, plus a coaxial digital output. The transport ran 100× fast-wind and search speeds, and 3-10× cue review speed. Audio (July 1993, p.65) published a use-and-listening test, though the review text is only fragmentarily preserved.
