COS Engineering S10 – Audiophile Network Switch
The COS Engineering S10 is far more than just an upgraded network device — it’s a precision-engineered LAN distributor purpose-built for high-fidelity audio streaming. Designed by audiophiles, for audiophiles, the S10 addresses the subtle but significant impact that noise and jitter have on digital audio playback.
Just like decanting a fine wine enhances its aroma and flavor, powering up the S10 brings out the texture, space, and musical nuance in your streaming system.
🔧 Key Highlights
Purpose-Built for Audio
The S10 tackles the loss of fidelity in music streaming with a refined integration of linear power supply, ultra-low jitter oscillators, and noise-filtered circuitry. This ensures reduced exogenous noise and enhanced audio purity.Independent Port Isolation
Featuring 8 RJ45 copper ports, each individually switchable via DIP switches underneath the chassis — this allows unused ports to be shut off, minimizing crosstalk and internal noise. Even the status LEDs can be disabled.Fibre-Ready Design
Includes 2 SFP optical ports for galvanic isolation and noise-free connection to compatible fiber-streaming equipment.Precision Engineering
12 bulk smoothing capacitors (4,700μF x 12)
4 low-noise regulators
Same toroidal transformer and AC filter used in COS’s reference DAC, the D10
Independent ultra-low jitter oscillators (0.025 ps) for each segment
High-grade aluminium chassis to shield against EMI
🧠 The Result?
A quieter background, deeper dimensionality, richer textures, and more dynamic expression from your music. You’ll hear it — especially in subtle ambience, vocal decay, and instrumental layering.
