HiBy RS2 II — Evolution of Pure R2R Analog Mastery

The HiBy RS2 II builds upon its legendary predecessor with a ground-up hardware overhaul, engineered for purists who demand uncompromising analog realism. Driven by HiBy’s advanced Darwin III architecture and a high-precision R2R resistor network, the RS2 II delivers a breathtakingly organic, natural, and immersive sound signature without the digital fatigue of standard chip-based players.

• Darwin III Architecture & R2R Core: Powered by a high-precision discrete R2R ladder network combined with a powerful FPGA housing 35,000+ logic elements and 40 DSP units, the RS2 II provides exceptional linearity, lower distortion, and authentic vintage warmth.

• Upgraded X1600E Processor & Larger Display: Equipped with a snappy X1600E dual-core processor and a gorgeous 3.55-inch high-resolution touchscreen (480 × 800), navigating your extensive music library is smoother and more intuitive than ever before.

• High-Power Discrete Amplification: Rebuilt with a quadrupled current amplification stage featuring 4x OPA1612 and 4x OPA1622 op-amps, the RS2 II delivers serious punch. It pumps out up to 630mW via the 4.4mm balanced output, providing effortless drive capability and stellar control for demanding multi-driver IEMs.

• PureAudio HiByOS Environment: Designed explicitly for distraction-free listening, it features no Android bloatware, no Wi-Fi, and no Bluetooth. The specialized PureAudio system creates a direct, bit-perfect audio pathway straight from your files to your ears.

• Massive Dual MicroSD Storage: Never leave a track behind. The RS2 II features dual active micro-SD card slots supporting up to 2TB each, allowing for a total of 4TB of local lossless storage capacity.
