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.
2 x OPA1652 Op-Amps
16 x Custom-designed Transistors
*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.
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!
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.
Qualcomm Snapdragon 665
Printed on a flagship-class 11nm lithography process, this SoC yields higher computational and graphics abilities. In conjunction with HiBy's many years of software and hardware integration experience, a high level of fluidity and responsiveness is achieved for all music app usage and more besides.
6GB+128GB Storage Configuration
6GB of RAM enables seamless app switching and stable background operation for instant access.
128GB of internal storage holds your full music collection and media files, delivering premium audiovisual experiences on the go. No more storage anxiety—effortless for both daily use and entertainment.
HiByOS based on Android 12
HiByOS, optimized for professional music reproduction from the ground up, bypasses SRC system-wide, including for third-party music players and streaming apps.
Also allows general user operations on par with mainstream smartphones， and underlying optimizations allowing smooth multitasking in both vision and sound.
4-section Independent Power Supply Design
Power supply section is designed by our engineer of over 30 years’ experience in power supply circuit design. Based on numerous sets of high flux, ultra-low internal resistance, fully shielded high power inductors, power supplies are made independently for digital, decoding, preamp and output stages, for pure, uninterrupted power without interference.
NDK Femtosecond Precision Crystal Oscillators
45.1584MHz and 49.152MHz femtosecond precision crystal oscillators onboard
For ultra-low phase noise and jitter for precision digital signals to be converted to exquisite analog details. You will feel the clarity and 3-dimensionality of every note even in highly dynamic, busy passages.
Abstract Artistic Back Panel
The back panel design is a futuristic work of art of aluminium waves splashing against a golden shore below a starry carbon sky.
Come to the island we call our own and be taken to music utopia.
Native DSD512 and PCM 768kHz/32bit Decoding
DSD512 is a high-spec format encoding audio signals at many-fold higher bitrate than CD quality, and frankly ridiculous sample rate. The highly resolving bit depth and high sample rate of PCM768kHz / 32bit also ensures more faithful capture than CD quality in all dimensions. In either case the result is more realistic and natural sounds.
Elegant Hyperbolic Design
Introducing bold asymmetrical lines for the chassis, two split curves define the visually interesting slanted surfaces which are also grip-friendly.
5.9”Huge Display, Beyond Full HD
Corning Gorilla Glass delivers scratch-resistant durability with crystal-clear transparency, paired with a 2160x1080 Full HD display for stunningly vivid visuals. Whether browsing, streaming HD videos, or gaming, every scene comes to life with rich layers and true-to-life colors—elevating your viewing experience with premium visual quality.
MQA 16x Unfolding
Supporting 16X full unfolding of MQA audio, not only increasing audio resolution but also restoring the original width and depth of sounds, immersing users in the audio venue. Jazz, pop, and classical alike become clearer, and more realistic, letting you re-acquaint yourself with your favorite standards in a new light.
*MQA (Mastering Quality Authenticated) is an award-winning technology owned by MQA Ltd., designed to pass the original master audio quality to the listener. MQA files are thoroughly authenticated by their owners and by MQA, and its origami unfolding technology ensures that the original master quality is retained at a compressed size and restored at playback time on supported equipment, while being backward compatible, being playable at reduced quality on non-supporting devices.
HiByCast System-wide Remote Control
Control all aspects of the device remotely via WiFi on any supported smartphone or tablet. Supports operation of HiByMusic app as well as third party apps.
Pre-installation of the HiByCast app from e.g. Play Store or App Store required
Audio output
With true line out, coaxial digital output, Bluetooth output etc. multiple output options available, the R6 pro MAX easily blends into a home HiFi system.
Coupled with system-wide HiByCast remote control, it becomes a whole new class of digital transport.
