A Bit About the COS S6

The COS S6 is a high‐performance HiFi Ethernet switch designed as a streamlined version of our flagship S10. It aims to make high‐fidelity audio streaming more accessible without compromising the core signal integrity that audiophiles expect.

Key Features & Technical Enhancements

Minimize Noise

RJ45 Magnetics

The S6 introduces several critical hardware upgrades to minimize noise and maximize data precision:

 Ultra‐Low Jitter: Equipped with an oscillator featuring 0.025 ps jitter for precise timing.

 Magnetic Isolation: The RJ45 ports and magnetics have been upgraded from an 8‐core to a 12‐core architecture to improve signal purity.

 Clean Power: Utilizes lower noise regulators to ensure a stable, interference‐free environment for digital processing.

 Versatile Connectivity: Features 2 SFP ports (100/1000Mbps) and 4 Copper RJ45 ports (10/100/1000Mbps)

RJ45 and magnetics are upgraded from 8 cores to 12 cores

LPS1 ( optional )

Ultra‐Low Noise Dual‐Channel HiFi Linear Power Supply

The Purest Path to Digital Perfection

Silence is the Foundation

In the pursuit of high‐fidelity sound, the "noise floor" is the enemy of detail. The COS LPS1 is an uncompromising linear power supply designed to liberate your digital components from the interference of standard switching power. By delivering a stable, ripple‐free current, the LPS1 ensures that your music emerges from a background of absolute silence, revealing the subtle textures and spatial cues of the original recording.

Dual‐Channel Precision

The LPS1 features two independent outputs, meticulously optimized to handle the distinct demands of your digital ecosystem:

 Output #1 (12V, 1A): Specifically tuned for high‐performance HiFi Ethernet switches, such as the COS S6.

 Output #2 (12V, 2A): Provides robust, low‐impedance power for high‐demand Ethernet routers and streaming

bridge devices.

COS LPS1

Audiophile‐Grade Architecture

We believe that the quality of sound is determined by the quality of the parts. The internal layout of the LPS1 is a testament to this philosophy:

 Swiss Schurter AC Input Module: Integrates a high‐performance switch, fuse, and medical‐grade filters to purify power at the source.

 Low‐Noise Toroidal Transformer: A dedicated core that ensures high efficiency and minimal magnetic leakage.

 Massive Energy Reservoir: Each channel is equipped with 10 ELNA 4,700uF audio‐grade capacitors (20 total), providing

a vast reservoir of power for instantaneous transient response.

 OP‐Amp Based Linear Regulation: Employs precision operational amplifiers for active noise suppression and rock‐solid

voltage stability.

Masterful Build Quality

 Substantial Presence: Weighing a solid 4 kg, the unit is designed to remain inert, suppressing micro‐vibrations that can

degrade signal integrity.

 Sophisticated Aesthetics: Available in Silver or Black to complement the most refined audio systems.

 Complete Connectivity: Includes two 1‐meter HiFi‐grade DC cables, allowing you to experience the upgrade

immediately.

S6 v.s. S10

When combined with the LPS1, the S6 would be the choice for a more detailed experience, more magic, more musical pleasure and some more flexibility due to the additional 12V power outlet. For a simple single box solution the S10 is the obvious choice.

Each product does have its own unique place in the offer so ask our dealers for more assistance or read on with some great reviews; see quote.

"While the S6 and LPS1 work brilliantly as a team, each follows suit in its respective role, so the choice between them ultimately comes down to individual needs and the willingness to pursue supportive hardware of this level" by Dawid Grzyb / May 5, 2026 http://hifiknights.com/reviews/accessories/cos-engineering-s6-and-lps1/
