Optimus Amplifier. 120W
This is a buyer’s market for this piece: at US$97, the asking price is well above the typical recent used range, which centers on US$31 median and US$55 at the 75th percentile, so it reads as ambitious rather than fair. Against that backdrop, I’d want a strong reason to pay up.
The upside here depends on what’s included and how complete the set is. If it’s clean, fully working, and comes with original accessories or packaging, that helps, but it still needs to justify a premium over the usual used pool. For a buyer, this is the kind of listing I’d only chase if the condition is unusually good or the item has some real scarcity appeal; otherwise, there are cheaper comparable buys available.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Optimus is best known as a RadioShack private-label audio brand rather than an independent hi-fi manufacturer. The name traces back to RadioShack’s in-house branding, with “Optimus” used on some products from the late 1960s and more broadly on audio gear in the 1980s and 1990s. It does not have a clearly identifiable standalone founder in the way a dedicated hi-fi brand would; its heritage is tied to the RadioShack retail chain in the United States.
The line covered a broad range of consumer electronics, including stereo receivers, amplifiers, speakers, cassette decks, turntables, and later some home-theater and portable audio products. Depending on the era, many Optimus components were sourced from overseas OEM manufacturers, especially in Asia, and sold through RadioShack’s stores as house-brand alternatives to mainstream consumer audio lines.
In the market, Optimus sits firmly in the mass-market and mid-fi category rather than the high-end segment. Today it is mostly remembered by vintage-audio collectors and RadioShack enthusiasts, with certain receivers and speakers drawing interest for their retro appeal and occasional value. It is not generally regarded as a boutique or audiophile-first brand, but some models remain noteworthy for solid build and nostalgic charm.
