Questyle SIGMA Pro — Flagship Portable Bluetooth DAC/Amp

Studio-grade performance. Portable form. No compromises.

SIGMA Pro is Questyle’s newest flagship “all-in-one” portable DAC/headphone amplifier, engineered to bring reference monitoring performance into a truly mobile form factor. It combines dual-mono ESS ES9069Q DACs, Questyle’s patented Current Mode Amplifier with fully discrete, fully balanced output stages, and an XMOS XU316 USB interface for master-grade decoding up to PCM 768 kHz/32-bit, DSD512 (Native/DoP), and MQA full decoding.

Dual ES9069Q (Dual-Mono) Current Mode Amp ×4 (Discrete, Balanced) XMOS XU316 USB PCM 768/32 • DSD512 MQA Full Decode Bluetooth 5.4 • Snapdragon Sound aptX Adaptive/HD • LDAC 3.5/4.4/6.35 HP Out 3.5 SE In • 4.4 BAL In Stereo Recording 48 kHz/24-bit Dual USB-C (Charge+Data) 4300 mAh • 12 h

Key Features

  • Patented Current Mode Amplifier + TTA: Four groups of fully discrete, fully balanced current-mode output stages under Questyle’s Three-Tier Architecture (TTA) deliver massive headroom, ultra-low distortion and speed.
  • Dual-Mono DAC Architecture: Two ESS ES9069Q chips in dual-mono configuration for superior channel separation, dynamics and resolution.
  • Serious Drive Capability: Peak figures up to 25 Vp-p output swing, >8 W peak power and 5 A instantaneous current (design headroom for difficult loads).
  • Three Headphone Outputs: 3.5 mm SE, 4.4 mm balanced and 6.35 mm full-size for instant compatibility from IEMs to full-size headphones.
  • Dual Analog Line Inputs: 3.5 mm SE (nominal 1 Vrms) and 4.4 mm balanced (nominal 2 Vrms) to integrate turntables/phono stages, mixers or other analog sources.
  • Stereo Line-In Recording: Record analog inputs as 48 kHz/24-bit digital audio over USB with simultaneous monitoring (UAC-class driverless on most OS).
  • Two USB-C Ports: One audio/data-only, one charge-only for play-while-charging and lower phone battery drain.
  • Bluetooth 5.4 with Snapdragon Sound: Supports aptX Adaptive, aptX HD, LDAC, SBC/LE Audio for high-quality wireless input.
  • Long Battery Life: 4300 mAh pack delivers up to 12 hours; smart battery management keeps long sessions stable.
  • Bauhaus-inspired Chassis: Sand-blasted aviation aluminum with Kunlun glass window — minimalist, durable, and striking on any desk.

Creator-Ready Connectivity

Optical (Toslink) and Coaxial inputs cover legacy digital transports; USB handles modern lossless playback from phones and computers. With 3.5 mm SE and 4.4 mm balanced analog inputs, SIGMA Pro drops into studio and Hi-Fi chains seamlessly. Switch gain manually to match IEMs, studio headphones or desktop monitors via line-out.

Wireless, Certified

Built on Qualcomm Snapdragon Sound, SIGMA Pro passes both Snapdragon Sound and Sony LDAC certification for robust high-quality wireless audio. It pairs broadly across ecosystems and supports modern Bluetooth codecs for both fidelity and stability.
