Key Features

Dual AD1861-J R2R DAC Chips — Pure Analog Soul
The R100 is built around two high-performance ADI AD1861-J R2R professional DAC chips, staying true to the core essence of analog audio. The classic R2R ladder architecture delivers a warm, natural timbre and nuanced reproduction of music’s true texture — far removed from the coldness often associated with digital audio.

Proprietary De-glitch Circuit — Precise, Distortion-Free Conversion
Equipped with a factory-built, proprietary De-glitch circuit that optimizes the signal processing workflow at the core of analog-to-digital conversion. It effectively avoids transient errors and signal distortion during conversion, while filtering out excess digital noise and harsh artifacts — ensuring every audio signal conversion is precise, stable, and pristine.

Web-Based PEQ Equalizer — Customized Personal Listening Acoustics
Featuring a convenient web-based PEQ customizable equalizer requiring no software installation or professional technical knowledge. Simply access the settings interface through a web browser to fine-tune the sound to your preference. The device provides Direct EQ, EQ1, and EQ2 three independent sound effect storage modes, supporting customized parameter saving with one click — eliminating repeated adjustments.

Masterful CNC Chassis — Solid Build Quality
The entire chassis is crafted using high-precision integrated CNC milling, formed through multiple fine grinding and polishing processes. The integrated body structure is solid and robust, effectively resisting daily vibrations and impacts. Clean, minimalist lines combine minimalist aesthetics with hardcore craftsmanship — perfectly complementing desktops, AV cabinets, and home environments.

Dual Transparent Viewing Panels — A Glimpse Inside
The chassis features dual oversized transparent viewing panels, offering a panoramic view of the precision hardware layout inside the device. From carefully selected core components to the intricate internal architecture, every detail showcases the craftsmanship behind a professional-grade audio system — combining visual transparency with advanced engineering aesthetics.

Proprietary SPDIF Digital Filter — Purified Digital Transmission
A dedicated self-developed high-precision SPDIF digital filter algorithm deeply optimizes the digital signal transmission logic, effectively suppressing JITTER clock jitter. It eliminates dry sound, blurred soundstage, dynamic compression, and loss of detail — expanding the musical soundstage and enhancing separation and three-dimensionality for a transparent, solid, and clean listening experience.

DSD High-Resolution Conversion — Analog Flavor Meets High-Res
Incorporating a self-developed DSD high-resolution conversion algorithm, the R100 allows the classic R2R decoding architecture to seamlessly accommodate DSD high-resolution audio input — preserving the warm, relaxed R2R analog timbre while combining it with the delicate analysis and rich details of DSD high-resolution sources.

Gold-Plated Connectors — Lossless Signal Transmission
Equipped with high-quality gold-plated input and output connectors with strong oxidation, corrosion, and wear resistance. Long-term use maintains tight, stable contact — effectively reducing impedance interference and signal attenuation for lossless, highly efficient transmission of all audio signals.
