Som ny. Blå. Fantastisk portabel Dac med 3.5 mm och 4.4 mm balanserad utgång. USB-C ingång. Finns i Stockholm.
At kr 1,500, this sits well below the kr 2,552 median and even under the kr 1,117 lower quartile’s neighborhood once you factor in how strong the used market usually is for compact Questyle gear; that makes it look like a genuinely attractive buy rather than a merely fair one. For a current-market DAC/portable DAC-amp of this caliber, that is a solid entry point if the unit is functioning properly.
The M15i is well liked for its clean, fast, highly resolving presentation, with the kind of refinement that suits IEMs and efficient headphones especially well. “Mint condition” is a real plus here, because these small USB DACs are most compelling when they’ve been lightly used and kept complete; just make sure the cable, adapters, and playback compatibility are all in order, since those practical details matter more than cosmetic wear on a piece like this.
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.
