The HiBy R6 ProII 2025 is a portable digital audio player. It runs HiByOS, an Android 12 based system customized for pro audio. HiByOS includes audio optimizations and a global SRC bypass that helps third-party apps preserve high bitrate audio. It can run Spotify, YouTube and other apps.
It uses two Cirrus Logic CS4308P DAC chips with 32-bit oversampling, a 123 dB dynamic range and THD+N below -115 dB. The DAC, I/V conversion and output stages each have independent hardware power rails. It decodes DSD 512 natively, plays PCM up to 768 kHz / 32-bit and unfolds MQA 16X.
One tap switches between Class A and Class AB amplifier modes. Class A uses dedicated op amps and transistors and suits high impedance headphones. Class AB is more efficient with power and heat and suits most in-ear headphones.
