The HiBy R6 Pro II is an Android-based digital audio player that sits between the R6 III and R6 Pro Max. The 2025 refresh swaps the original AKM DAC section for dual Cirrus Logic CS4308P chips, and reviewers describe the result as a more contrasted, vivid sound with better resolution than the AKM version. It runs open Android 12 on a Snapdragon 665 with 6GB RAM and 128GB storage, and offers switchable Class A or AB amplification with up to 632mW balanced output. It suits listeners who want a streaming-capable player with a punchy, detailed character and don't need the extra power of the Pro Max.

Reviewers treat the 2025 DAC swap as a genuine change in character rather than a small tuning tweak. They report more contrast, a more vivid presentation and better resolution than the AKM-based original, and frame it as an alternative flavor rather than a clear upgrade.
The HiBy R6 Pro II is a digital audio player built around dual Cirrus Logic CS4308P DAC chips. The 2025 version replaces the previous generation's AK4191EQ and dual AK4499EX DAC section. It runs open Android 12 on a Qualcomm Snapdragon 665 processor, with global SRC bypass.
The amplifier switches between Class A and Class AB and delivers up to 632mW balanced output. The DAC, I/V stage, low-pass filter and amplification sections each have a discrete power supply. Two NDK femtosecond crystal oscillators (45.1584MHz and 49.152MHz) sit near the DACs to control jitter.
The back panel has a wave pattern with embossed detailing. The player has 6GB of RAM and 128GB of internal storage. It plays native DSD512, PCM up to 32bit/768kHz, and MQA with 16x unfolding.
