Darwin audio architecture

DAP-class complete audio architecture onboard for a groundbreaking audio experience. We apply the Darwin architecture, the winner of endless accolades in the high-end DAP arena, for the first time in a portable headphone DAC/amp, utilizing R2R design for the DAC, ensuring a sound with emotion, warm, wet with loose naturalness, at the same time preserving the FIR filtering and NOS/OS switch, etc. of the Darwin system for maximum flexibility.

NOS mode
NOS mode is non-oversampling, responding more immediately and directly to signals, converting the digital signals to the analog output directly, bringing a more analog sound signature, It is more suitable for music files/streams of 192kHz sample rate or above.

OS mode
Oversampling mode easily removes aliasing artifacts via the tried and true combination of the oversampling and ultrasonic lowpass filter, HDR, and NOS/OS mode switch, yielding superior measured performance; enables all functions of the Darwin architecture, realizes personalized adjustments of sound signature, adapting to different earphones.

MQA 8X unfolding
