At US$800, this is above the price the STA-200 was widely known for new, which was US$499 in some retail channels and US$1299 at launch, so the asking price is on the high side for a used unit unless the condition and extras are exceptional. Recent used sightings I found cluster closer to US$570-US$634, so US$800 looks ambitious rather than a clean market buy.
What makes it worth considering is that the STA-200 is a genuinely well-regarded 80Wpc Class AB amp with a Goldmund/JOB connection, a clean, fast, low-noise presentation, and enough drive for many sensible speakers. If this one is truly mint, original-owner, and includes box and packing, that helps—but at US$800 I’d want strong proof of condition and provenance, because the upside here is the sound, not collector rarity.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
NuForce emerged in 2005 as a California-based innovator in high-end audio, co-founded by engineer Jason Lim, whose prior work at tech giants like Motorola and Oracle informed its pioneering designs. The company quickly distinguished itself by securing three US patents in Class D amplifier technology, establishing a reputation for efficient, high-performance amplification that challenged traditional solid-state approaches. In the early 2010s, Lim spun off its high-end assets into NuPrime Audio in 2014, while Optoma acquired the core NuForce brand around 2015, integrating it into a lineup blending pristine audio with video systems.
NuForce specialized in compact, audiophile-grade components, particularly digital amplifiers, DACs, and wireless streaming solutions tailored for home cinema and hi-fi setups. Its portfolio emphasized modular separates—preamps, power amps, and integrated units—alongside headphones, cables, and accessories that prioritized clarity and power efficiency. Post-acquisition, the focus expanded to complement Optoma projectors, though the brand retained its core strength in Class D tech for both stereo and multi-channel applications.
Positioned as a mid-tier disruptor, NuForce earned acclaim from outlets like The Absolute Sound for value-driven performance that punched above its price, appealing to savvy buyers seeking modern efficiency without ultra-premium excess. Though less prominent today under Optoma, its legacy endures among enthusiasts valuing innovative, patent-backed amplification in a boutique market segment.
