At £665, this sits above the £500 median and even clears the £631 75th percentile, so it reads as a bit ambitious rather than a bargain. It is not wildly out of line for a desirable vintage receiver, but it’s priced at the top end of the recent used market.
The appeal here is the classic Optonica charm: solid late-era build, full-size stereo muscle, and the kind of presentation that draws enthusiasts to these receivers in the first place. If it’s clean, fully working, and ideally includes the original knobs, wood case, or paperwork, that helps justify the ask; otherwise, a buyer should want some room to negotiate.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
# Optonica
Optonica was a high-end audio subdivision of Sharp Corporation, the Japanese electronics manufacturer. Launched in 1975 (with some sources citing 1976), the brand was created to compete directly with established premium audio makers including Pioneer, Yamaha, Sansui, Nakamichi, and Marantz during the golden age of hi-fi. Sharp designed, built, and marketed Optonica products entirely in Japan, positioning the line as a serious contender in the luxury stereo market.
The brand's product portfolio centered on integrated amplifiers, receivers, and complete stereo systems aimed at discerning audiophiles. Optonica equipment was engineered to deliver high-fidelity sound reproduction across the mid-to-high power range, with models typically rated between 40 and 60 watts per channel. The brand maintained a focused approach, concentrating on core audio components rather than diversifying across numerous product categories.
Optonica's tenure in the high-end audio market proved relatively brief, effectively ending by 1982 as a serious competitor. The brand was revived in 1988 as a consumer electronics line encompassing stereo television receivers, VCRs, portable cassette players, and surround-sound receivers, but this iteration lacked the prestige of the original audio division. Production ceased entirely by 1991. Today, Optonica equipment from the late 1970s and early 1980s holds appeal among vintage audio collectors and enthusiasts seeking well-engineered Japanese hi-fi from that era.
