The R8 II is tuned in keeping with the “Portable Concert Hall” ethos of the original R8, taken one step further: in filling out the large soundstage projected by the series with a new level of detail and density, the R8 II brings the true openess and power of an orchestral performance into a portable listening environment, all thanks to the all-new Darwin-MPA architecture.

The R8 II features a multiphase PWM array, 16-way current-mode DAC. The Darwin-MPA (Multiphase PWM Array) continues the flexible design of Darwin-R2R, having most of the same distinguishing features as Darwin-R2R. To work with the internal delta-sigma modulators, input signals are oversampled to 128x via the flexible Darwin v2 filter system (which may optionally emulate various types of non-oversampling DAC functionality via the 3 built-in NOS filters or follow a hybrid approach via the built-in Darwin Ultra filter). The oversampling (or non-oversampling) processing follows a cascaded FIR design with a highly precise 1024-tap opening stage.

The output stage includes 16 channels of current-mode D/A conversion, in conjunction with I/V conversion amplification and “lowpass” filtering only at MHz frequencies thanks to the exemplary oversampling (or non-oversampling) implementation for an exquisitely open sound of extraordinary bandwidth that is provided at a modest power consumption, in keeping with the identity of a “portable” DAP.

DSD1024 is one of the highest quality digital audio formats on the market, encoding music at an even higher bitrate and sample rate, yielding higher quality reproduction than CD quality. PCM1536/32 also ensures more detailed capture and processing of audio for a more realistic and natural sound.

Universally acclaimed class-A amplification powered by 2 ADA4625-2 driver opamps and 16 custom transistors for zero crossover distortion and fast transient response. Unlock extra control over your earphones with Class A mode, increasing the sense of power, density of presentation, at the same time increasing control over the drivers for the kind of detailed, nuanced sound befitting a flagship no matter how complex the passage.

Class AB mode yields better battery life, less heat, at a sound quality level that will already satisfy most earphones on the market.

Turning on Turbo mode increases power reserves by 25%, unlocking high-power power supply lines with one touch of the screen. Turbo mode is full throttle, with increased max voltage swing, max volume, etc.

The R8 II's huge 18000mAh battery delivers up to 21 hours of audio playback when in 3.5mm single ended + Class AB amp mode! Enjoy your music with flagship performance, even on long trips.

A pure copper battery case is substantial in the hand, highly efficient in heat dissipation and keep your player's internals cool in the hottest situations.

The R8 II's chassis is made of surgical grade stainless steel material befitting the surgical precision of its audio quality. Stainless steel posseses high tensile strength, exemplary resistance to rusting, wear and tear, and is able to retain its stunning visuals through long term use.

An asymmetrical design language of dual curves realizes an elegant curved surface that is at once visually stunning and also comfortable to hold.

In the R8ll, HiBy breaks new ground in, incorporating an ALCANTARA back face. ALCANTARA is no ordinary brand: designed and made in Italy, with a serious and certified commitment to sustainability and unlimited variation in the resulting product. Beautiful and functional, it is the key to a modern, worldly and yet unique visual and tactile sensation.

Hiby has created an all new design language, which upgrades the elegant yet utilitarian language of the original R6 Pro with the dual curve design introduced in the R6 Pro ll.

The R8 ll is a new work of art by HiBy in the realms of industrial design, ergonomics, colour, material and finish. Meticulously designed lines coupled with the mirror-finish polished medical grade 316LVM stainless steel chassis sides, and an exclusive ALCANTARA backplate, sets out an unparalleled feast of sight and sound for its owners.
