Summary
The Questyle MEX dongle DAC debuts at Tokyo's Autumn Headphone Festival 2026 as the first portable USB DAC to use current-mode amplification. Four proprietary SiP CMA modules and dual ESS ES9219Q chips deliver up to 384 kHz / 32-bit PCM and DSD256. At $210 USD, its companion app falls under China's National Intelligence Law, Article 7; the hardware PURE mode switch lets users bypass the app entirely.
