The HiBy R6 III 2025 is a portable Android Hi-Res audio player and an update to the 2023 R6 III. It uses four CS43198 DAC chips for decoding and supports 32-Bit/768kHz PCM, native DSD512 and 16x MQA unfolding.
The amplifier section has dual OPA1652 op-amps, 16 hand-matched transistors and 4 ELNA capacitors. It switches between Class A and Class AB modes. Class A gives constant full-power output for full-sized headphones and low-efficiency IEMs. Class AB is more efficient and balances sound quality with battery life. Two independent crystal oscillator clocks, at 45.158MHz and 49.152MHz, provide low phase noise and low clock jitter.
The player runs open Android 12 on a Qualcomm Snapdragon 665 chip, so media apps from the Google Play Store can be installed. System-wide bit-perfect audio is supported across apps. The back panel is glass with a diamond-cut pattern. The 3.5mm and 4.4mm headphone and line-out ports are independent.
