Yamaha MX-2000 (1988–1993)
English-language sources say little about the Yamaha MX-2000. The record shows a stereo power amplifier sold in Japan from 1988, at the peak of Japanese high-fidelity development. List price was around 300,000 yen (about 4,500 DM in Europe). It is reported to use a pure Class A design with Yamaha's HCA (High-speed Current Amplifier) circuit, and to have been built with particularly high-quality components throughout. It weighs 28 kg and measures 473 × 170 × 469 mm, finished in titanium. Power consumption is rated at 350 W, and total harmonic distortion is given as less than 0.002%. There was no remote control.
Contemporary review coverage in the English-language audio press seems sparse. One residential installation was documented, with the MX-2000 powering multiple speakers (Sound and Communication, May 1990, p.55). Collectors know it for its build quality and low distortion. Specific performance measurements, input/output configurations and damping factor remain undocumented in the available record.
