The HiBy R8ii is designed for audiophiles who prioritize sound quality and seek an intricate music experience. Among its peers, the R8ii stands out with features that appeal especially to those who crave high-fidelity audio in a portable form.
One of the most significant advancements in the HiBy R8ii is its use of DARWIN Digital Signal Processing (DSP). This technology allows for precision in the digital-to-analog conversion process, reducing common digital artifacts and enhancing the overall sound fidelity. The device employs pulse-width modulation (PWM) for its DAC, which avoids the traditional delta-sigma modulation found in many other DACs. This method leads to fewer timing errors and reduces intersymbol interference, contributing to the clarity and realism of the audio output.
Furthermore, the HiBy R8ii is built with high-quality components that support its powerful performance, including a discrete Class A amplifier capable of driving a wide range of headphones. Its robust metal chassis, although slightly heavier than some might prefer, adds to the device’s durability and premium feel. The large and intuitive touchscreen enhances user interaction, making navigation through extensive music libraries seamless.
# Advantages:
– Timing Accuracy and Phase Consistency: R2R DACs offer better timing accuracy and phase consistency due to simultaneous processing of all bits. This leads to a better preservation of the positioning of instruments and the naturalness of the sound.
– Low Artificiality: R2R DACs present sound in a more natural and analog-like manner. Unlike Sigma-Delta DACs, they involve less digital processing and filtering, resulting in a sound that feels more organic and less “processed”.
– Dynamic Range: High-quality R2R DACs usually provide a wide dynamic range, enhancing the richness and detail of the sound.
Sigma-Delta DAC Structure
Sigma-Delta DACs use a single or a few high-speed switches (typically a transistor) for converting digital signals to analog. This switch continuously compares the input digital signal at a very high frequency (oversampling) and results in a low-frequency signal.
# Advantages:
– High Resolution: Sigma-Delta DACs can process at high resolutions, making them suitable for audio formats higher than CD quality.
– Cost-Effectiveness and Compact Size: This type of DAC can often be constructed with fewer components, which reduces production costs and device sizes.
_The point to keep in mind_
The choice depends on the intended use and personal preferences. While R2R DACs are preferred by audiophiles who favor the warmth and naturalness of analog sound, Sigma-Delta DACs offer more modern, high-resolution, and cost-effective solutions. Both technologies offer specific advantages, but R2R DACs tend to provide a superior experience in terms of sound quality and accuracy. (See Cayin RU6, RU7, HiBy R2, RS6, and FC6)

Design and Build Quality: The device boasts a robust and elegant metal chassis, which might be slightly heavier and bulkier than some competitors, but this compromise is reasonable considering the high-quality components housed within. Its touchscreen is responsive and high-resolution, making it easy to navigate through music collections and enhancing the overall user experience.
In my examination, the HiBy R8ii reveals a thoughtful layout on the lower edge. To the left, it sports both a 4.4mm balanced headphone output delivering up to 6Vrms, which can boost to 7.5Vrms in Turbo mode, and a maximum of 710mW at 32 ohms. There’s also a 3.5mm single-ended output offering 3Vrms and 220mW at 32 ohms. On the right, the same size outputs are present but configured for Line Out purposes, which neatly supports various audio setups. This arrangement not only ensures versatility but also aligns with the needs of both casual listeners and audiophiles who demand high-quality audio and strong power handling.
User Interface and Operating System: HiBy OS impresses with its user-friendly interface, offering extensive customization options that allow users to tailor their music listening experience. The system is smooth and intuitive to navigate without any lag or stutter, which makes managing music both simple and enjoyable.
HiBy R8ii Sound Quality
In my use, the HiBy R8ii has proven to excel in delivering a sound that’s both broad and finely detailed. Listening across different music genres, I’ve noted its ability to produce clear and vibrant sound across a wide range of frequencies. The dual DAC setup really shines when it comes to its dynamic range, offering deep, resonant bass and crisp, clear highs that make even familiar tracks come alive. It’s impressive how it captures every little detail—the pluck of a guitar string, a breath taken before a vocal line, and even the subtle harmonics in the background are all rendered with crystal clarity, making for a deeply engaging listening experience.
Moreover, the soundstage of the HiBy R8ii is something I find particularly striking. It provides a sense of width and depth that adds a tangible sense of space, which is quite uncommon in portable devices. This quality, which you’d typically expect from larger, stationary sound systems, not only boosts my enjoyment of live recordings but also brings a level of realism to studio tracks. It allows for an accurate sense of where each instrument is positioned within a three-dimensional space. These features make the HiBy R8ii more than just a music player; it’s like having a portable concert hall that recreates the atmosphere and presence of each performance I listen to. This exceptional fidelity has made the R8ii a standout in my collection, appealing to both my casual listening and serious audiophile needs, making it a real treasure in the world of high-end portable audio.
Against 600 ohm beast__
In pop music, I hear the rhythms with all their volume. But I can’t get the classic dynamic driver bass kick from the k240. After all, it was originally brought to life for studio use. So rather than the bass that makes me feel constricted, I hear details that I’ve never heard in any IEM before thanks to the big power in the HiBy R8ii.
In the progressive art music of The Aristocrats, it’s the same logic. It’s as if the whole canvas has grown in size, and I’m listening closely through a floor stander speaker…Especially when I listen to the Primuz Chamber Orchestra version of it, I’m speechless. Likewise when I listen to Gitan from Graou’s Seoul concert. It’s as if the instruments and the audience are incarnate.
Additionally, R8ii looks like it blew an essence of life into YASASHISA of Fuiji Kaze. Every second of that track is highly realistic, and making me feel that this is the music!
Connectivity Options: The device performs excellently in terms of wireless capabilities through Bluetooth and Wi-Fi. It also offers various digital and analog output options, ensuring compatibility with almost any audio setup.
Battery Life: The battery life is quite satisfactory for a high-performance device. It can last through a day of heavy use, although battery drain is faster at maximum volume output and when playing high-resolution files. But considering the overall weight of that portable brick, one can claim that it is the battery itself :p
Price and Value: While the HiBy R8ii carries a high price tag, the features, flexibility and sound quality it offers justify the cost. It presents an excellent investment opportunity for audiophile-grade users.
