Luxman A-371 (1992–1993)
The Luxman A-371 is a stereo integrated amplifier built in Korea between 1992 and 1993. It came in black or champagne gold. The champagne version was the A-371 G, and it typically shipped with a remote control - the RA-371, a system remote that also handled a matching tuner and cassette deck over Luxman's "SYSTEM BUS" connection. In Germany the A-371 G listed at 1,198 DM. It was part of a small stack: the A-371 was reviewed and sold alongside the D-351 compact disc player, and the two turn up together as a system to this day.
The surviving manuals say more about the amp's connections than about its measured performance. The rear panel had phono jacks rated at 2.5 mV input sensitivity into 47k ohms, accepting MM, MI, or MC cartridges. The manual has its own caveat: a low-output MC cartridge needs a step-up transformer or head amp, since the A-371's phono stage won't reach it. There were line inputs for tuner, CD, DAT, tape, AV, LD, and VCR, plus video switching for laserdisc and VCR with a TV monitor output. Two pairs of speakers could run independently or together off the A and B terminals. There was a single switched AC outlet rated at 100 watts max. The service manual covers two finishes and includes specifications, connection guidelines, and a parts-and-functions section.
Most of the numbers aren't in the record. No clearly-attributed frequency response, signal-to-noise ratio, or channel separation have surfaced. The manufacturer document does give 0.05% distortion (ref. 1kHz) and dimensions of 438×125×363 mm. A paruvendu.fr listing shows figures like 0.05% THD and a 20 Hz - 20 kHz response, but the extraction is ambiguous about whether those belong to the A-371 or another model on the same page. The 0.08% figure that circulates is actually from the A-331, a different amp. The one weight figure available, 9.5 kg, comes from a wiki entry. A January 1994 review of the A-371 and D-351 praised the front panels as "clean and well laid out and not at all daunting to the user". It is a rare bit of period commentary, though the review is thin on test data.
The documented weak spot is the volume control. At least one owner reported a crackling, noisy pot ("шуршит регулятор громкости"), which is the classic age complaint on these amps. A speaker relay is also listed as a spare on the used market, so that part is findable. Asking prices are all over the map. A Ukrainian seller listed an A-371 plus D-351 stack at 14,000 UAH, and eBay and HifiShark both track the model, but no reliable average has been established.
