HiBy R6 Pro Max Digital Audio Player

The R6 Pro Max sits at the top of the R6 line, and it's built like it: HiBy's biggest R6-series battery, an 8-way independent I/V amplification design, and the first 40W fast charging on any of their portable players. It's the R6 Pro II's flagship-grade DAC upgrade, not a subtle refresh.

Type and Technology

• Dual ESS ES9039MS Pro flagship DAC chips
• 8-way independent I/V amplification built from OPA1612 op-amps, plus 4x OPA1622 and 4x ELNA capacitors for a warmer, tube-adjacent analog stage
• Four-way independent power supply system separating amplification, conversion, data, and control circuits
• Qualcomm Snapdragon 665 SOC, open Android 12 with system wide SRC bypass
• Dual independent femtosecond crystal oscillators
• 5.9 inch 1080p IPS display, 40W PD3.0 fast charging
• Native DSD1024, PCM 32bit/768kHz, MQA 16x unfolding

Sound Character

Reviewers single out the dual ES9039MS Pro DACs and 8-way I/V design for a smooth, analog leaning presentation with an expanded soundstage, a step up from the R6 Pro II's more precision-focused AKM tuning. Measured balanced output runs up to 697mW with a rated THD of 0.0003%, genuinely flagship-adjacent figures in an R6-series body.

Build and Comfort

• 147.45 x 75.2 x 21.8mm, 425g

• 8200mAh battery with a 65W USB-C GaN charger available

Best For
