Integra M-588F (documented 1992–1995)

Documentation on the Integra M-588F is thin. Most of what is known comes from period listings. It was a two-channel power amplifier from Onkyo's Integra line, rated at 200 watts per channel. Integra's own advertising in HiFi-Stereo (February 1993, p.80) ran with a bragging headline that no loudspeaker company could make the same claim. The ad described a balanced dual-mono design with low-impedance drive capability and discrete output stages.

The smaller Integra M-502 (140 W/ch) shared the same dual-mono, low-impedance, discrete-output architecture. That suggests the 588F was the bigger sibling near the top of Integra's early-nineties power-amp line. The model also shows up in Audio's annual amplifier directories, in the October issues from 1992 through 1995. No original price, exact production years, or independent lab measurements have surfaced so far.
