Pure Analog Sound with Discrete R-2R Technology
The R30 utilizes a self-designed, fully discrete R-2R ladder network DAC for the purest analog sound. This innovative module converts digital signals into analog with precision, bypassing modern delta-sigma DACs’ high-frequency switching to ensure a direct and natural sound reproduction. With its rigorous resistor network, it achieves exceptional audio purity.
True-1 Bit Decoding for Accurate DSD Playback
Equipped with a True-1 Bit DSD D/A converter, the R30 provides native support for DSD1024. This advanced technology delivers an oversampling ratio 16 times greater than the standard DSD64, ensuring an extremely detailed and dynamic sound. By bypassing PCM conversion entirely, it preserves the integrity of the original pulse density modulation, resulting in a more accurate and engaging listening experience.
Advanced Digital Filtering for Pristine Sound
The R30 incorporates state-of-the-art digital filtering, utilizing multi-order adaptive algorithms that upsample digital signals intelligently. This cutting-edge technology eliminates in-band aliasing distortion while enhancing resolution and dynamic range. The result is a pristine, high-definition sound free from the harshness often found in conventional DACs, delivering a smoother, more natural listening experience.
Superior Timing with OCXO and GCLK-02 Clocks
The R30 features an SC-Cut OCXO clock, ensuring exceptional thermal stability and precision accuracy. Paired with the GCLK-02 clock module, this system uses advanced PLL technology to lock the frequency with 1Hz-level precision, reducing jitter and improving overall audio performance. For the ultimate in audio quality, the R30 also supports external clock connections, further enhancing sound fidelity.
Dedicated Power Supply for Maximum Performance
The R30 is powered by two high-quality toroidal transformers, ensuring isolated power for both digital and analog circuits. This dedicated power supply minimizes mutual interference, allowing for cleaner, more stable operation of each component. With such a refined power system, the R30 delivers exceptional sound performance, capturing every detail in your music.
