AK4191 + dual AK4499EX
Utilizing AKM's new flagship DAC duo, AK4191EQ+dual AK4499EX, in current output mode with complete separation of digital conversion and analog rendering.
All-In Audio Architecture
All-In Audio Architecture equips the 8 DAC output rails of the AK4499EX each with their own I/V conversion, fully unleashing their potential; The dual AK4499EX are each set to dual mono output, and all rails of both DACs contribute fully to both balanced and single-ended operation. Such strategic enhancements to the AK4499EX's operation in conjunction with ultra-hard output stage circuit design powers yield sound quality worthy of a new flagship.
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.
Faithful reproduction
With vanishingly low distortion and colouration, every note is resolved accurately and dynamics are rendered in full. Whether piano notes that resonate in the heart as well as the room, violin notes crisp and clear, every breath of the player clearly heard through a flute, or any other instruments, you will never miss a single detail on the R6 pro II. You will hear every finger movement on strings, on keys, air vibrations inside every instrument as clearly as if seen with your eyes in closeup.
Class A/AB dual amplification circuits, freely switchable
Dual independent amplification circuit design, freely switchable on the fly via touchscreen. Well regarded Class A amplifier driven by 2 OPA1652 and 8 NXP bipolar transistors for zero crossover distortion and 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.
Industry-leading DSD1024 and PCM 1536kHz / 32bits native decoding
DSD1024 is one of the highest-spec formats currently on the market at the moment, 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 PCM1536kHz / 32bit also ensures more faithful capture than CD quality in all dimensions. In either case the result is more realistic and natural sounds.
MQA 16x unfolding
16x unfold of MQA files, giving master-tape quality audio re-constitution, richer replay of the sound as intended it's a take-you-to-the-concert / studio experience!
MQA (Master Quality Authenticated) is an award-winning technology that captures and reproduces the sound of the original studio master in a file that's small enough to stream and down- load. HiBy is collaborating with MQA to deliver truly original sound quality to listeners.
Abstract artistic backplate
The all new backplate 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.
Godly curves
Introducing bold asymmetrical lines for the chassis, two split curves define the visually interesting slanted surfaces which are also grip-friendly.
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.
5.9" large hi-res display
Coming Gorilla glass, 2160x1080 resolution, oleophobic-coated
HiByOS based on Android 12
HiByOS offers fine volume control, clearing of unwanted extra sound effects, systemwide bitperfect audio even for third-party apps, and all manner of other audio-related system optimizations over regular Android 12 and even any other flavour of customization found on the market. Meanwhile it offers the same Ul experience as mainstream smartphones and multi-task switching smoothness on a level with flagship smartphones thanks to kernel optimizations!
Systemwide HiByCast remote control
Breaking previous boundaries, HiByCast supports systemwide remote control of all device functionalities from any smartphone or tablet. Third-party app opening and control, browsing are all remote accessible.
Multipurpose audio input
Also supporting USB DAC in functionality, for use as computer external sound card or digital amplifier for smartphones, etc. Two-way Bluetooth enables Bluetooth audio input for use as a Bluetooth receiver for wired headphones.
Multipurpose audio output
Supports line out, coaxial digital output, USB audio out, Bluetooth audio output etc., allowing you to easily integrate the R6 pro II into your home audio system. In conjunction with systemwide HiByCast, unlocks all new frontiers of convenience as a digital.
