HiBy R6Pro II 2025 – Lossless Hi-Res Portable DAP
Dual CS4308P Flagship DACS
The industry’s first portable HiFi player featuring Cirrus Logic’s flagship CS4308P DAC now in an advanced dual-chip configuration (twin CS4308P DACs working in parallel). This groundbreaking architecture delivers exceptional audio resolution and unparalleled driving power.
The CS4308P is Cirrus Logic’s latest flagship 8-channel high-performance DAC, engineered for audiophile and professional audio systems. Featuring a 32-bit oversampling architecture, it achieves a 123dB dynamic range with THD+N below -115dB, delivering crystalline purity of sound, crafting an immersive listening experience with exceptional density and layering.
Class A/AB Dual Independent Headphone Amplifier Circuits
Featuring independent Class A and Class AB headphone amplifier circuits, freely switchable via one-touch system control for optimized listening scenarios. The widely acclaimed Class A amplification eliminates crossover distortion and delivers ultra-fast transient response.
Turn on Class A amplification to unlock stronger drive control at the same time as enhancing power and density of the sound, handling full-size headphones and complex loads such as multi-hybrid IEMs with aplomb.
Class AB amplification mode yields longer play time, lower heat emissions, and is perfectly sufficient for most IEMs on the market, achieving the perfect synergy between sound quality and everyday usability.
Audio Excellence Easy on the Ears
Specially optimized for mid-low frequencies, the sound signature delivers significantly improved listening comfort. With natural, well-balanced tuning-rich in detail yet never harsh-it achieves a smooth and transparent audio performance. Both vocals and instruments carry a warm, velvety texture, creating fatigue-free immersion perfect for extended listening sessions. An ideal blend of premium sound quality and enduring auditory comfort.
Dramatically Increased Power Output
The new R6Pro II delivers a significant power leap-measured at 632mW via 4.4mm balanced output-effortlessly driving multi-driver, high-impedance headphones. The formidable power output not only elevates the headphones transient speed and dynamic performance, making music sound richer, more detailed, and powerfully alive, delivering a listening experience that combines thunderous impact with refined control. The sonic performance rivaling flagship-tier!
