The HiBy R8 II Alloy Version is conceived in the spirit of the original R8, but goes a step further with a new level of detail thanks to the new Darwin‑MPA architecture.

This new aluminum edition gives the R8 II a refined and refreshed look compared to its predecessor, featuring the new ultrasuede back material.

Darwin‑MPA retains the flexible design of Darwin‑R2R, with most of the same hallmark features of Darwin R2R.

To work with the internal delta‑sigma modulators, input signals are oversampled to 128x via the Darwin v2 flexible filter system. The oversampling process follows a cascaded FIR design with a 1024‑tap, high‑precision opening stage.

The 16‑way current‑mode DAC, together with I‑V conversion and the low‑pass at the output stage, creates a more detailed sound with good power efficiency.

An asymmetric dual‑curve design language creates an elegant curved surface that is both visually striking and comfortable to hold.

The HiBy R8 II Alloy Version uses a high‑end ultrasuede back plate for a premium texture and feel. Light, soft, and durable, it is very comfortable to hold and use. Its texture and temperature control make it comfortable for extended use.

This new HiBy DAP features universally acclaimed Class A amplification, driven by two ADA4625‑2 op‑amps and 16 custom transistors for zero crossover distortion and fast transient response.

Enjoy additional control over headphones with Class A mode, which increases the sense of power and presentation density while improving driver control and grip for detailed, nuanced sound worthy of a flagship—no matter how complex the passage.

Class AB mode offers longer battery life, less heat, and a sound quality that already satisfies most headphones on the market.

Activating Turbo mode increases power reserves by 25%, unlocking the high‑power rails with a single tap on the screen.

Includes four Elna tube‑type audio capacitors for an analog, detailed sound. In addition, 28 high‑density, high‑capacity tantalum capacitors.

Two dedicated high‑frequency precision crystal oscillators at 90.3168 and 98.304 MHz provide near‑atomic clock precision for all digital audio samples.

A large custom battery designed for impactful power consumption levels ensures the proper headroom to use Class A and Turbo modes.

The digital, D/A, preamp and post‑amp circuits are powered individually with non‑crossing power.

Headphone amplifier circuit: the headphone amplifier is powered by a low‑ripple DC/DC transformer + 3 fully shielded, high‑power inductors with high flux and low IR.

Ultrasonic low‑pass: the low‑pass filters are powered by a DC/DC transformer + 6 high‑PSRR LDOs (+/‑) that power the left and right channels independently.

DAC power supply: the DAC is powered by a DC/DC transformer and 2 ultra‑low ripple LDOs, powering the left and right channels independently.

The solid copper battery enclosure feels substantial in hand, dissipates heat very efficiently, and keeps the player’s internals cool even in hotter situations.

The R8 II Alloy Version employs Qualcomm’s Snapdragon 665 to achieve power efficiency while ensuring a smooth UI and multitasking experience with uninterrupted music.

With HiBy’s latest, you get generous storage for a high‑performance experience.

• 8 GB RAM: to enjoy more content, faster.

• 256 GB ROM: for virtually unlimited streaming downloads with or without an additional microSD card.

Re‑coded from the ground up for streamlined operation, higher CPU efficiency, and faster response.

HiByOS’s exclusive DTA technology avoids Android SRC at the system root, enabling bit‑perfect audio from third‑party apps—just plug in your headphones.

It also enables bit‑perfect audio over USB audio output.

Breaking boundaries by enabling remote control of all R8 II functions from smartphones and tablets alike, HiByCast lets you open and operate even third‑party apps on the R8 II remotely from your other smart devices—opening the door to using the R8 II in home entertainment, connected to audio receivers, etc., while you control it from the sofa.

DSD1024 is among the highest‑quality digital audio formats available. It encodes music at even higher bitrates and sampling frequencies, delivering playback quality beyond that of a CD.

PCM1536/32 also ensures more detailed audio capture and processing for a more realistic, natural sound.

The SoC’s processing power enables unprecedented 16x MQA unfolding, reproducing the original master tape from ever smaller source files.

The R8 II Alloy Version features four ports:

• 3.5 mm headphone out
• 4.4 mm headphone out
• 3.5 mm line out
• 4.4 mm line out

Features fast, very stable dual‑band Wi‑Fi to enjoy all your high‑quality online music.

Also supports music upload and download via DLNA/AirPlay/Wi‑Fi.

Supports Bluetooth and multiple high‑resolution Bluetooth audio codecs such as UAT, LDAC, aptX, aptX HD, SBC, etc.
