At US$1,215, this Questyle CMA800i asking price is ambitious, sitting well above the median of US$160 and the 75th percentile of US$649 from your 17 recent comparable listings, though it remains below the current new/open-box market floor of roughly US$639–US$1,499 seen on eBay and Reverb. The price is hard to justify as a bargain unless the unit is in pristine original-owner condition with all accessories, remote, and USB cable included, especially since typical used deals for this model cluster far lower.
The CMA800i is a highly regarded integrated DAC and headphone amp that pairs Questyle’s legendary current-mode amplification (from the CMA800R) with a robust DAC supporting 24/192 PCM and TrueDSD up to DSD128, delivering 1W at 32Ω and 8.6V XLR output. It’s essentially a compact, high-performance preamp/headphone solution that saves buyers roughly US$1,000 compared to buying the CMA800R and CAS192D separately. If this listing is clean, fully functional, and includes the remote and cables, it’s a solid opportunity for enthusiasts who value current-mode sound and digital flexibility, but only if the condition is verified and the price reflects that premium.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Questyle Audio emerged in December 2012 from Shenzhen, China, founded by Jason Wong, an innovator whose university experiments in 2006 sparked the company's signature Current Mode Amplification (CMA) technology. This patented approach, filed globally just 18 months after launch, revolutionized amplifier design by adapting current amplification from high-speed communications to audio, prioritizing lossless, high-fidelity playback. Rooted in China's tech hub and manufactured by Foxconn, Questyle quickly built a global footprint through relentless R&D focused on overcoming environmental and technical barriers to pure sound.
The brand specializes in premium digital-to-analog converters (DACs), headphone amplifiers, and integrated desktop solutions, with standout portable dongles like the M12 and M15 embodying CMA alongside ESS flagship chips for PCM 384kHz/32-bit, DSD256, and MQA decoding. Their lineup emphasizes minimalist elegance, from compact mobile amps to robust desktop DAC/headphone amps like the Q192, delivering effortless, high-resolution performance without gimmicks.
Questyle holds a confident position in the high-end portable and desktop hi-fi market, earning acclaim as a premium challenger to established names through superior build, explosive detail, and V-shaped dynamics. Audiophiles praise its trouble-free excellence and technological edge, cementing its reputation among discerning buyers seeking innovative, no-compromise audio gear.
