At US$50, this NuForce uDAC2 is an ambitious ask, sitting above the 75th percentile of recent USD listings where the median is US$40 and the top quartile starts at US$48. It is not a bargain; the price is roughly 25% higher than the typical market median for this used DAC, so you should only pay it if the condition is pristine and includes original accessories.
The uDAC2 remains well-regarded as a compact USB DAC/headphone amp that delivers 24-bit/96kHz resolution and 80mW of power into 16Ω loads, making it a solid entry-level option for portable or desktop listening. Its main upside is simplicity and USB bus power, but given the US$50 price, verify there’s no channel imbalance or headphone-jack “lupanie” (crackling), which were documented failure points that can undermine its value. If those issues are absent and it’s original-owner clean, it’s still a fair buy for the performance, just not a deal.
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.
