The HiBy RS8 is HiBy's new flagship with Android 12 and Darwin II audio architecture. It stands out for the integration of a Qualcomm Snapdragon 664 and R2R DAC with class A amplification.

For more resolution and definition, this RS8 supports up to DSD1024, PCM1536 and 16x MQA deployment. All built on a pure titanium chassis and a level of perfection on par with the best.

The HiBy RS8 mounts a titanium chassis monocoque formed by 6-stage CNC with 17 advanced construction processes, for a resistant and high-quality exterior, with a texture that is comfortable and pleasant to hold. 

It is topped by a rotating volume wheel for very smooth volume adjustments.

The Darwin architecture is the new high-resolution digital signal processing architecture developed in-house by HiBy. In a revolutionary evolution of the traditional R2R architecture, the system includes for the first time advanced features such as linear FIR filter, non-linear harmonic control, switchable upsampling/NOS and DSD bypass on portable equipment. The flexible end-to-end architecture is fully configurable, creating endless possibilities for future upgrades and endless evolution.

The R2R resistor ladderconsists of 12 high-speed switches and 184 high-precision resistors, twice the number of the latest generation, effectively increasing dynamic performance and fidelity at low signal levels.

The additional addition of a DC offset correction circuit allows the use of a fully DC-coupled output stage, further improving the impulse response. Sample rates up to 1024x DSD and 1536kHz PCM are supported, exceeding the specifications of many full-size systems in a portable device.

The core of the DAC architectureconsists of 12 high-speed switches and 184 high-precision resistors. 

The digital signal drives, through high-speed electronic switches, the activation voltage that must be modulated by the resistor network to obtain an analog voltage waveform corresponding directly to the digital signal, avoiding the high-frequency modulation of the DS DACs for a more natural and transparent shape. and emotional presentation.

NOS mode has no oversampling, responds more immediately and directly to signals, converts digital signals to analog output directly, providing a more analog sound signature. It is best suited for music files/streams with a sample rate of 192 kHz or higher.

Oversampling mode produces superior measurement performancer; Enables all features of the Darwin architecture, makes custom sound signature adjustments, adapting to different headphones.

The HiBy RS8 mounts carefully selected gold-tantalum capacitors used to ensure clean power output, higher power supply ripple rejection for lower THD of the resulting system.

Composed of2 dual OPA1652+8x NXP bipolar transistors, the class A amplifier features “zero” zero-crossing distortion and instantaneous transient response.

Maintaining maximum output at all times, the Class A amplifier maintains ideal driving and control characteristics over full-size headphones, high and low impedance IEMs, and all types of loads. The RS8 maintains a composure befitting a modern flagship while playing any complex musical passage through any headphone load

• Headphone amplifier voltage supply: default ±6V.
• Turbo at ±7.5 V.
• By Power = V^2/R, turbo mode produces 56.25% additional power.

*Heat dissipation and battery drain are significantly increased when turbo mode is activated.

A huge battery, custom designed for the occasion, ensures adequate power delivery and battery life for the Class A amplifier to produce immediate musical transients and also last the distance: 12 hours via 3.5mm SEand 8 hours via 4.4mmbalanced for longer listening.

The digital, DAC, preamplifier and postamplifier circuits are each supplied independently so that there is no interference.

The headphone amplifier circuit is powered by 2 high-quality DC/DC transformers and 6 fully shielded high-power inductors with high magnetic flux, ultra-low internal resistance.

The ultrasonic low-pass filter is powered by another DC/DC transformer and 7 LDO regulators, which power the left and right channels independently.

The R2R ladder is powered by another DC/DC transformer and 2 ultra-low ripple LDOs that power each channel independently.

Features apure copper battery casefor high heat dissipation efficiency for cool internal temperatures even in the heaviest operating scenarios.

Using an advanced 11nm process, the Snapdragon 665 enables smooth operation of multiple applications at the same time, instant response to music search, and the potential use of any audio DSP.

Its8 GB of RAM allows for seamless simultaneous operation of multiple streaming applications; The256 GBof internal storage allows for the storage of large local music libraries.

Features Android 12 rewritten from the core for simpler operation and more efficient use of powerful hardware for better responsiveness.

With Corning Gorilla Glass and oleophobic coating, 1920x1080 resolution, 443ppi, 16:9 aspect ratio.

The Direct Transport Architecture (DTA), unique to HiByOS, bypasses sample rate conversion from deep in the system kernel, allowing even third-party applications to enjoy seamless output at the original sample rate, whether from the headphone outputs, line outputs, or the USB Digital Audio Output.

Breaking all barriers, supporting system-wide operation of all device functionalities from a smartphone/tablet, including the operation of third-party applications.

The SoC's massive processing power makes possible an unprecedented 16x display of MQA data, playing back the original master tape from increasingly smaller source files.

MQA (Master Quality Authenticated) is an award-winning technology that captures and reproduces the sound of the original studio master in a file that is small enough to stream and download. HiBy is collaborating with MQA to bring truly original sound quality to listeners.

The HiBy RS8 has a 3.5mm headphone output and a 3.5mm and 4.4mm line output.

Dual band WiFito double the speed and stability of the connection, supporting ready music streaming.

Supports DLNA/AirPlay/WiFi music file transfer.

Supports two-way Bluetooth reception/transmission, compatible with all major Bluetooth audio formats such as UAT, LDAC, aptX, aptX HD, AAC, SBC, etc.

Supports charging rates of up to 20W for fast battery recharging.
