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
All-new user interface tailored to the RS2. Simplified menu structure is more intuitive and user-friendly than ever. Green & gold theme--firmly luxurious.
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.
An output stage designed completely around R2R
Fully musical, realistic, natural and analogue, highly energetic when called for, fully immersive for the listener.
NOS / OS mode switch
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.
256-tap adjustable FIR filter
The Darwin architecture is capable of up to 16x oversampling, with a variety of AA filters suited to various design goals, e.g. phase linearity, high fidelity; also adaptable to the characteristics of different earphones, guaranteeing the suitability of the RS2 to all sorts of earphones.
Precision dual crystal oscillators, FPGA clock regeneration system
Dual precision crystal oscillators at 45.185MHz / 49.152MHz effectively reduce phase noise and jitter to -140dBc/Hz@1kHz offset.
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.
MQA 8x unfolding
MQA 8x unfolding offers reproduction of the original performance on par with the master tapes, transporting you to the same room with the artists!
MQA (Master Quality Authenticated) is an award-winning audio technology that enables music fans to stream the original master recording into their home in the highest possible quality. The MQA file is fully authenticated, backward compatible, and small enough to stream, so you can play MQA on any compatible device. Wherever there is audio, MQA delivers the best sound.
Supporting all the main music encoding formats, supporting PCM up to 384kHz / DSD hardware decoded at up to DSD256.
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.
Dual card storage
With slots for *2* micro SD cards, supports storage of up to 4TB and simultaneous usage of the two cards. Please note that the database of the RS2 supports a maximum of 20,000 tracks. There is a firmware update planned to support 50,000 tracks. Additional tracks can be manually browsed via the folder view on the player.
Long play time
Up to 10 hours continuous play time. Standby for up to 40 days.
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.
