An output stage designed completely around R2R

Running on the PureAudio HiByOS, the RS2 also enjoys targeted optimization of system level audio processing, providing a clean, pure audio playback pathway, ensuring a purely audiophile music experience.

Retro design language are melded into the tough bold lines of the R family. The volume knob, being the element you most often come in contact with, is a diamond-cut, artisan-grade masterpiece. Functionality is not sacrificed, the touchscreen supports touch controls and double-tap-to-wake

The Darwin audio architecture is our in-house developed all new hi-res audio processing architecture; improving greatly upon traditional R2R technology, it incorporates a host of studio-grade functionality such as linearity compensation for the R2R network, adjustable FIR filter, harmonic controller, NOS/OS switch, etc. in a highly portable device. The flexible architecture is fully adjustable in-house, yielding infinite possibilities for evolution of this model and the next.

NOS mode is non-oversampling, yielding raw response to signal changes; OS mode is adapted to the various additional functionalities of the Darwin architecture, realizing personalized adjustments to the sound qualities to adapt to different earphones and different tastes.

Luxurious output stage circuitry

Utilizing current mode amplification, the output stage amplifies current via a OPA1652 and an LPF consisting of 2x OPA1612, offering high and clean input voltage and current to the output stage for exemplary transient and dynamic response. In conjuction with 2x flagship class OPA1622 amplifier chips, 4 independent channels of current mode headphone amplification, and the professional digital volume controller NJW1195A, the circuit guarantees maximal fidelity of the output to the input, and maximal control over the headphone drivers.

Uncharging mode--Independent battery operation as USB DAC

Press button to toggle charging in USB DAC mode--uncharging mode reduces battery consumption on smartphone and isolates device from external power supply noise.

USB DAC / coaxial digital / Line Out all supported

Inheriting the high configurability of other HiByOS devices, the RS2 may be used as a USB DAC (e.g. playing computer / smartphone audio) but also output to other USB DACs (e.g. outputting audio from the RS2 to other USB DACs), and even output its audio as coaxial digital / line out signals.

Format support

Supporting all the main music encoding formats, supporting PCM up to 384kHz / DSD hardware decoded at up to DSD256.
