Integra SV-810PRO (1991–1998)
The Integra SV-810PRO is an A/V integrated amplifier that appears in period press under two names: at least one test report called it the Onkyo A-SV810PRO, while a later catalog listing used the Integra tag. Either way, the same sizable home-theater unit is being described.
HI-Fi-Stereo-Buyers (August 1991, p.34) tested it as an A/V integrated amplifier, noting video inputs for a videodisc player and a DBS receiver, each fitted with both an S-video connector and a composite connector, plus a fourth video circuit. Audio (October 1991, p.86) profiled it in a home-theater roundup, highlighting a series of on-screen displays that made its advanced capabilities easy to use — it added a center channel to the front and rear channels for more accurate sound effects — and called the 39-pound unit a powerhouse.
A HI-Fi-Stereo-Buyers catalog listing (1998, p.85) supplies the closest thing to a surviving spec sheet: all-discrete circuitry including a phono preamp, metal-film resistors, polypropylene capacitors, Extended Dynamic Power (EDP) circuitry, 104 dB signal-to-noise ratio, dimensions of roughly 17 × 11 × 4 inches, and a $399 price.
That's nearly the whole record. No confirmed production dates, no measured output figures, no service lore. The references span 1991 to 1998, but beyond a few magazine mentions, the SV-810PRO is a model the archive knows mostly by reputation.
