Questyle MEX

MEX is Questyle's next-generation mobile DAC/headphone amplifier. Dual ESS ES9219Q DACs and patented SiP current-mode amplification delivers ample driving power, outstanding dynamics and finely detailed, natural sound. The TTA Three-Tier Architecture combines precise preamplifier control with H/M/L gain to suit high-impedance headphones and sensitive earphones.

- Switchable between two modes, PURE original sound mode that faithfully reproduces the music's timbre and detail, and TUNE mode that allows you to select between tuning presets or fine-tune with PEQ on the Questyle app.
- Patented SiP Current-Mode amplification drives even 300 Ohm headphones with dynamic headroom and fine detail with low distortion and fast transient response.
- Two ES9219Q DACs support up to PCM384kHz/32-bit and Native DSD256. The TTA Three-Tier Architecture helps the DAC and headphone amplifier work together to provide a suitable drive foundation for different headphones.
- Three gain levels and 64 volume steps provide a more precise match for both high-impedance headphones and sensitive earphones. Left/right balance adds control for personal habits and specific pairings.
- Dynamic Range Enhancement (DRE), DAC filter control, along with preset and parametric EQ settings are all controllable from the Questyle app. Q-Code allows MEX users to save, import and share tuning profiles with each other.
- Microphone pickup opening on the device and support for 3.5mm CTIA headsets enable everyday voice use.
