The mobile concert hall
The R8 II is tuned in keeping with the "Portable Concert Hall" ethos of the original R8, but takes it a step further, filling the large soundstage projected by the series with a new level of detail and density, truly bringing the openness and power of an orchestral performance into a portable listening environment, all thanks to the all-new Darwin MPA architecture.
reviews
"I am both surprised and impressed with the performance of the HiBy R8 II DAP. The quality of the performance is exciting, engaging, and highly resolving. It has a lot more drive and energy with tested pairings compared to the original R8 and a vocal presence and midrange openness that might tick more boxes than the RS8's equivalent."
HiBy R8 II Review — Headfonics
"The HiBy R8 II sets a new standard for neutral-sounding DAPs, especially below the 2000$ range. Its super dark background, precise stereo imaging, and spacious soundstage create an immersive listening experience that remains faithful to the recording. With its honest and uncolored reproduction, the R8 II invites you to rediscover your music with newfound clarity.
With its premium build, advanced technical specifications, and great sound performance, the HiBy R8 II stands as a good example of the brand's dedication to advancing the realm of portable audio. We recommend the HiBy R8 II to audiophiles and music enthusiasts seeking a higher-end digital audio player with a neutral sound. It will be added to ours DAP Recommendations. Kudos to HiBy."

External Design
An asymmetrical design language with two curves creates an elegant, curved surface that is both visually impressive, breathtaking and comfortable to hold.
The light dances along the curves, just as the music dances through its circles!
High gloss surgical grade 316LVM stainless steel.
A surgical-grade stainless steel chassis that matches the surgical precision of its audio quality. It has a high tensile strength, an exemplary resistance to rust and wear and is able to to maintain stunning appearance even with long-term use, even with long-term use.
Alcantara Future Fabric - an extraordinary rendezvous with HiFi
With the R8II, HiBy breaks new ground in chassis design by using an Alcantara back. Alcantara is no ordinary brand: designed and manufactured in Italy, with a serious and certified commitment to sustainability and
and unlimited variation possibilities of the product, beautiful and functional, it is a key to modern, cosmopolitan and unique visual and tactile impressions.
When we at HiBy crossed Alcantara with the R8 II, we created a completely new design language that the elegant yet functional language of the original R6 Pro with the double curve design of the R6Pro II.
The R8II is a new work of art from HiBy in the areas of industrial design, ergonomics, color, material and surface. Its carefully designed lines combined with the highly polished case sides made of medical 316LVM Stainless steel and the only material that the designer from all over the world has chosen for the Rear panel - Alcantara - offers its owners an incomparable feast of optics and sound.
Breaking the limits of the material, creating the impossible
After extensive communication with Alcantara, we found that we have a common goal, to break with traditions and overcome perceived boundaries.
When designing the R8II protective case, we boldly chose a new design: We use Bayer UE95 TPU as the main protective cover and added Alcantara, which matches the back plate of the R8II, as the side material for the Housing.
The two unique materials merge to create a unique feel. It offers excellent load-bearing capacity, Shock resistance and shock absorption and combines with the design language of the R8II, thanks to the timeless Combination of high resistance and fine feel of Alcantara, the material of the future.
Portable Concert Hall MkII
The R8 II is tuned in line with the "Portable Concert Hall" ethos of the original R8, but goes a step further by filling the large soundstage that the series projects with a new level of detail and density.
The R8 II manages to bring the openness and power of an orchestral performance into a portable listening environment, thanks to the completely new Darwin MPA architecture.
Darwin-MPA - Multiphase PWM array, 16-way DAC in current mode
The Darwin-MPA (Multiphase PWM Array) continues the flexible design of the Darwin-R2R and has most of the the same features as Darwin-R2R. To work with the internal delta-sigma modulators, the Input signals are oversampled 128x using the flexible Darwin v2 filter system (which can optionally emulate various types of non-oversampled DAC functions).
The oversampling (or non-oversampling) processing follows a cascaded FIR design with a high-precision 1024-tap opening stage. The output stage comprises 16 channels with current-mode D/A conversion in conjunction with I/V conversion Amplification and "low-pass" filtering only at MHz frequencies thanks to the exemplary oversampling implementation (or non-oversampling) for an exquisite, open sound with exceptional bandwidth, which is
modest power consumption, which corresponds to the identity of a "portable" DAP.
Dual headphone amplification (Class A / AB), freely switchable
Two independent headphone amplifier circuits, switchable via software. Universally recognized Class A amplification Powered by 2 ADA4625-2 driver opamps and 16 custom transistors for zero crossover distortion and fast
transient response.
Class A mode gives you additional control over the headphones, which increases the feeling of power and density while improving control over the drivers for a detailed, nuanced sound - one Sound worthy of a flagship, no matter how complex the passage.
The Class AB mode ensures a longer battery life, less heat generation and a sound quality that already exceeds most headphones on the market.
Turbo mode
Turning on Turbo Mode increases power reserves by 25% and unlocks powerful power lines with just a touch of the screen.
Touch the screen. Full power at full throttle!
Increases maximum voltage swing, maximum volume, etc.
Headlight power supply: Standard-- ±6V; Turbo mode: ±7.5V
(*Turning on Turbo Mode will significantly increase heat output and battery consumption, resulting in ~20% shorter runtime per Charge)
Flagship-quality analog circuit components
Includes 4 tube-like Elna audio capacitors for an analog, detailed sound character. In addition, 28 tantalum capacitors with high density and capacity - an equipment that is worthy of a king (of audio technology)!
Dedicated femtosecond precision crystal oscillators
Two dedicated high-frequency femtosecond precision quartz oscillators with 90.3168 and 98.304 MHz provide Atomic clock accuracy for all digital audio signals.
12000mAh battery
The huge battery is specially designed to handle the shocking power consumption and offers enough space for class usage A and Turbo modes.

The headphone amplifier is powered by a DC/DC transformer with low ripple and 3 fully shielded high-flux IR high-performance
power inductors.
The low-pass filters are powered by a DC/DC transformer + 6 high PSRR +/- LDOs, which independently supply the left and right channels.
and right channel.
The DAC is powered by a DC/DC transformer and 2 LDOs with extremely low ripple, which drive the left and right channels independently of each other.
