Flagship Performance Compacted

Being the compact flagship, the RS2 II utilizes the same Darwin III architecture as the flagship RS8 II full-size flagship, with further updated core processing components suited to the alternative DAC hardware onboard;

As the compact flagship, the RS2 II uses the same Darwin III architecture as the full-size flagship RS8 II, with its core processing components further updated to suit the different DAC hardware onboard. The Darwin architecture is fully developed in-house by HiBy and has been granted a national patent (No. ZL202110679601.X). It is already a leading technology in the industry for a full end-to-end audio processing chain, and it takes another step forward in the RS2 II. The architecture includes a clock and clock manager, DSD/PCM configuration, 32x oversampling, an FIR filter, harmonics control, R2R modeling with resistor parameters, left and right R2R networks with LPF stages, volume control, and SPDIF output.

Femtosecond-grade Dedicated Audio Crystal Oscillators

The dedicated 45.158MHz and 49.152MHz crystal oscillators clock audio at both 44.1 and 48kHz multiples perfectly with less than -140dBc/Hz @1KHz offset of phase noise, ensuring phenomenal micro-detail recovery and instrument separation free from jitter.

All-new FPGA Digital Processing Engine

DARWIN III comprises an all-new FPGA featuring over 35,000 logic units and 40 high-speed, high-performance DSPs, giving life to high-tap FIR filtering, a plethora of AA filter choices, and special effects such as harmonics generation / control, giving rise to a fully software-controllable digital processing and analog conversion pipeline.

D/A Conversion Circuit
Driven with Distinct R2R Technology

The Darwin III architecture utilizes a precisely matched R2R network of resistors. The digital signal passes through a network of voltage dividers actuated via high-speed electronic switches, each voltage division choice accurately converting to an analog voltage level directly corresponding to the requested digital level, thus conquering …thereby avoiding the high-frequency noise and digital glare introduced during digital modulation processes, making the sound more natural, clear, and emotional!

This raises the overall THD+N to lower than 0.0008%!
Raising the bar for competition in similar or even higher price brackets, bringing true audio innovation via actual in-house research.

Grandiose
Amplification Circuitry

PureAudio HiByOS

Utilizing the mature, stable HiByOS, PureAudio version. We spent over a decade perfecting the ultimate audio OS dedicated to hi-res audio playback. HiByOS optimizes audio quality from the root of the system upward, hammering out a pure audio playback chain, guaranteeing a pure listening experience that moves your soul.

The standard version body proper weighs only 156g*.
Take it with you everywhere without feeling weighed down.
Device width has been decreased compared to the first generation, complete with improvements to chassis details, improving hand-holding, especially for small hands.

Upgraded SoC

Upgraded to the X1600E SoC, sporting dual cores, for silky-smooth Ul operation and faster response. Skip songs, browse libraries, and seek through songs more quickly and without stuttering during several-hour-long sessions. Coupled with HiByOS for first-class stability.

Touchscreen Upgrade

45% larger screen size sporting 122% the number of pixels, the all-new 3.55″, 480×800 screen greatly improves display of Ul elements and album art, with a tiny bezel nearing a full-screen body design;
Combined with the Ul customized for the deluxe RS series, with a signature eye-catching green and gold color scheme. The large size and resolution make the Ul more intuitive and easier to use than ever!

Signature Sound DNA Carried from RS8 II to RS2 II

The classic warm undertones of traditional R2R technology are preserved in the RS2 II, making sounds realistic, natural, and fully analogue; it is especially effective at rendering fully emotional vocals.

Powerful Driving Capability Broad Compatibility

Perfectly Suited to Both Headsets and In-Ear Monitors.

USB DAC / Coaxial /Line Out Fully Supported

Inheriting the signature multifunction qualities from HiByOS, the RS2 II may be used as a computer sound card, smartphone outboard DAC+amp, etc.
Also supporting digital output via coaxial and analogue output via line-out, you will find a place for the RS2 II in any audio system.

Dual micro-SD Slots

Each supports up to 2TB for a massive 4TB total capacity, supporting integrated use of both cards at once!
