Flagship Dual ES9218P DAC Chips

The HiBy R3 Pro Saber adopts dual brand-new ES9218P DAC chips. At the heart of this chip is an award-winning SABRE DAC technology from ESS with a HyperStream Ⅱ modulator. The ES9218P HiFi SoC leverages the company's patented 32-bit HyperStream architecture that can support up to 32-bit 384kHz PCM and DSD256, ensuring audiophile quality sound all the way to the headphones.


2.5mm Powerful Balanced Output

Equipped with 2.5mm balanced output, the R3 Pro utilizes four independent amplification channels, bringing more powerful amplification, wider soundstage, and exquisite detail. Although this device features heavy-hitting syling cues, including translucent backplate, sanded aluminum highlights, its body is very tiny.

Dual Crystal Oscillators

Adopting an independent clock system with NDK low-phase-noise oscillators, the HiBy utilizes a high-performance FPGA chip onboard. This independent 22.5792MHz and 24.576MHz crystal oscillators supply correct time base signals to x44.1 and x48 sample rate music data respectively, reducing jitter, increasing accuracy of digital music reproduction, and reducing the effect of phase noise on sound quality.


Bluetooth 5.0 & Two-Way UAT

Supporting Bluetooth 5.0, HiBy R3 Pro Saber features the ultimate in Bluetooth HiFi, two-way UAT. UAT is a shortcut of Ultra Audio Transmission, which is an all-new Bluetooth audio codec developed in-house at HiBy. It can support an industry-highest sample rate of 192kHz at an industry-highest data bandwidth of 1.2Mbps, it can even adapt and optimize itself to different music genres.
