Luxman D-351 (1991–1993)
The Luxman D-351 was the company's serious attempt at a high-end single-box CD player in the early Nineties. It sold from 1991 to 1993 at $1,900. Period advertising showed it as part of a coordinated multi-room system alongside the K-351 cassette deck and M-111 amplifier, as shown in Audio (October 1991, p.70).
The D-351 stands out for its power supply and output stage. It uses two transformers, with separate supplies for the digital and analogue sections. The final output stage is pure Class A, dual-mono. That is a lot of engineering spent on the analogue side, and it fits the published figures: a 122dB signal-to-noise ratio, 102dB dynamic range, and harmonic distortion rated at just 0.0018%. Line output is a standard 2V.
The transport uses a Sony KSS-190A laser pickup. Two independent sources confirm it, which helps anyone hunting a replacement part decades later. The player is big: 465 x 104 x 390mm and 10kg, which fits the dual-transformer layout inside.
Beyond that, the record is thin. No information survives on the specific D/A converter, the digital inputs, or what model sat above or below it in Luxman's lineup. The archive has no documented owner reviews or common-failure reports.
