Yamaha AX-2000 (1987)
Little is documented about the Yamaha AX-2000. The record shows an integrated amplifier, listed in the December 1987 issue of HI-FI-Stereo (p.94) alongside Yamaha's then-current component lineup. The same issue noted that Yamaha's CD players of the period, models in the $499 range, had full-function remote controls and the company's Hi-bit circuitry, for a claimed signal-to-noise ratio of 118 dB.
Past that brief listing, almost nothing survives in the archive's research material. No specifications have been confirmed - power output, THD, frequency response, weight, dimensions. There is no original price, no design or circuitry detail, no production run dates, and no contemporary review that measured its performance.
The AX-2000 appears to have been part of Yamaha's late-1980s amplifier push, when the company was pairing its integrated amps with the CD players and tuners mentioned above. Without corroborating documentation, this is all that can be said: the AX-2000 is a real model, it was an integrated amplifier, and it was on the market by late 1987. The specs, and how it sounded and compared, are unrecorded in the sources available to this archive.
If you own an AX-2000, have a service manual, or have spotted one in a period brochure, that documentation would close the largest gap on this page.
