Luxman MX-100
The MX-100 is one of those Luxman models with almost no paper trail. It's identified as a power amplifier, and a serious one on paper, but beyond the basic specifications the record is thin. No production years, no original price, no period reviews. Audio magazine (April 1986, p.105) listed Luxman among brands in a dealer's advertisement, indicating the company's presence in the high-end audio market of that era. A dealer advertisement in the same issue listed Luxman among brands like Carver, Nakamichi, and Yamaha.
What is documented comes from the spec sheet. The MX-100 is a hefty piece: 48.5 kg, measuring 478 × 245 × 473 mm, rated at 500W into 8Ω and 1000W into 4Ω. Frequency response is listed as 5Hz - 500kHz (+0dB, -3dB), with THD at 0.005% and a signal-to-noise ratio of 120dB. Input sensitivity is 1.4V into a 50kΩ impedance. It takes both unbalanced RCA and balanced XLR inputs, with separate speaker outputs for left and right channels.
Several things are missing from the record: whether the 500W figure is RMS or peak, the conditions under which THD was measured, damping factor, gain, and any mono-bridged specifications. There's also no documented matching preamplifier. No source says what Luxman intended to pair with this amplifier, or where it sat in the lineup relative to models like the M-05 or L-570.
The MX-100 was a high-power Luxman amplifier from the era when the company was competing at the top end of the market. Its weight alone, over 100 pounds, suggests a substantial power supply and chassis. Nothing in the documented record covers sound quality, reliability, or real-world performance.
