Luxman M-1600 (1976)
The Luxman M-1600 is a solid-state stereo power amplifier. Luxman released it in July 1976 at ¥146,000 in Japan. It's a plain wood-cabinet power amp from the mid-1970s, rated at 80W + 80W into 8Ω from 20 Hz to 20 kHz, with total harmonic distortion of 0.03% or less at that rating. Signal-to-noise ratio is spec'd at 100 dB or better, and input sensitivity is 700 mV into 33kΩ. It weighs 16.5 kg and measures 476 × 182 × 257 mm (W×H×D).
Luxman described the M-1600 as a pure complementary circuit, directly coupled through all stages, with a generously-rated large-capacity output transistor. There's a level meter on the front panel, and the wood cabinet is finished in rosewood. The M-1600 is often paired with the Luxman CL-350 preamplifier. French vintage-audio site audiovintage.fr calls that combination a classic, and the two were commonly sold together. One owner on a forum noted that the amp has input level controls, so it can run without a separate preamp, and described the sound as "surprisingly warm and clear". That's a single informal report, not a measured review.
Documentation on the M-1600 is thin beyond its basic specs. There's no confirmed production end date, and sources disagree slightly on the year (Audio Database says July 1976; HiFi Engine lists 1978). No professional period reviews have surfaced in the Archive's sources.
