SW-10PRO
Built for Music Lover & Audiophiles
The SW-10PRO is a network switch purpose-built for high-end digital audio streaming. Designed for discerning audiophiles, it offers an integrated solution that delivers pure, high-precision, and stable network performance, combining advanced switching, Master Clock synchronization, and network isolation technologies into one meticulously engineered device.
The Master Clock section features a dual thermostatically-controlled SC-CUT OCXO with ultra-low Phase Noise better than > -110 dBc/Hz, paired with a top-tier PLL clock synthesizer. This configuration delivers the most accurate and stable clock signals to both switch zones.
In a high-end streaming audio system, the SW-10PRO elevates the listening experience with a remarkably lower noise floor, blacker background, greater clarity, and rock-solid imaging stability. By eliminating unwanted interference and optimizing clock precision, it unlocks the full potential of your music, revealing finer details, richer textures, and a deeper emotional connection to every performance.
Power. Foundation of good sound
To effectively isolate AC power interference and prevent cross-talk between different system sections, the SW-10PRO equipped with two ultra-low-noise NORATEL toroidal transformers. These provide independent power circuit paths for the OCXO Master Clock and the Network Switch circuitry.
Dual Mono Toroid Transformer ensures that the Master Clock and all clock distribution modules operate in an ultra-low-noise environment, further reducing phase noise and enhancing clock accuracy. At the same time, it delivers robust and stable power to the 2.5G/1G network controllers, SFP optical ports, and isolated zones.
CNC-Machined Solid Billet Aluminum Chassis
The chassis is precision CNC-machined from a solid block of aerospace-grade aluminum, significantly reducing overall resonance and increasing structural rigidity compared to standard assembled aluminum enclosures. This also enables effective isolation between functional sections, minimizing interference.
-
Compartmentalization
Additionally, the solid billet design allows for precise internal compartmentalization, enabling effective isolation between functional zones such as the clock module, power supply, and network switch circuits. This minimizes internal cross-interference and helps maintain signal purity. The high thermal conductivity of aluminum also contributes to passive heat dissipation, improving overall system stability and longevity without the need for noisy active cooling solutions.

Ultra-Clean Power. Unmatched Performance.
SW-10PRO is purpose-built for enthusiasts in pursuit of the ultimate in audio fidelity and data performance. Its advanced power architecture features a total of 18 segregated multi-stage linear regulation circuits, designed to deliver ultra-clean, stable, and low-noise power to every critical subsystem.
Minimizing interference, reducing jitter
This ensures optimal operating conditions for the clock modules, switching engines, and optical interfaces—minimizing interference, reducing jitter, and preserving signal integrity throughout. The result is a genuine high-end solution that elevates both sonic realism and digital precision in serious streaming audio systems.

Reference Grade OCXO Master Clock
The Master Clock section features a dual thermostatically-controlled SC-CUT OCXO with ultra-low Phase Noise better than > -110 dBc/Hz, paired with a top-tier PLL clock synthesizer. This configuration delivers the most accurate and stable clock signals to both switch zones.
Each functional zone is physically and electrically segregated for optimal isolation.
Timing Perfected
Optical Isolation for Pure Audio Networking
The 2.5G high-speed main switching zone and the 1G ultra-quiet, isolated audio zone are linked via built-in dual single-mode optical fibers, delivering true optical-electrical isolation between network traffic and sensitive audio components.
This advanced architecture not only eliminates electrical noise and ground loop interference but also creates a clean, interference-free network environment—essential for achieving the highest level of digital audio streaming purity and stability.
