SOtM sMS 500 Server

The Next Generation Begins

Technology exists to serve music.

A New Chapter in SOtM Network Audio

For more than a decade, the sMS-200 has earned the trust of music lovers around the world,
becoming one of SOtM’s most recognized network audio products.

Throughout this journey, SOtM has remained focused on one fundamental question:

How can digital audio be delivered with greater purity and fidelity?

Rather than pursuing specifications for their own sake, SOtM has always believed that technology should exist
to preserve the integrity of music. This philosophy has driven years of research into ultra-low-noise and
ultra-low-jitter technologies, shaping every product the company creates.

The sMS-500 carries this philosophy forward while introducing an entirely new hardware
architecture developed for the next generation of network audio.

More than a performance upgrade, the sMS-500 establishes a new foundation designed to meet the evolving
demands of modern digital audio while remaining true to SOtM’s uncompromising approach to musical reproduction.

Designed from the Ground Up

The sMS-500 has been completely redesigned from the motherboard upward.

Its new hardware architecture integrates every major element, including system design, power architecture
and processing platform, into a dedicated environment optimized exclusively for music playback.

Rather than maximizing computing performance, every engineering decision has been made to minimize electrical
noise, improve signal integrity and preserve timing accuracy throughout the entire playback chain.

The result is not simply a faster system, but one capable of reproducing music with greater
transparency, naturalness and emotional realism.

This newly developed hardware architecture will also serve as the foundation for the next generation
of SOtM network audio products.

The Evolution of Eunhasu

The sMS-500 continues to use SOtM’s proven Eunhasu operating system, now specifically
optimized for its new hardware architecture.

While maintaining the intuitive user experience familiar to existing SOtM users, the software has been refined
to fully realize the capabilities of the new hardware platform.

Improved responsiveness, enhanced stability and ongoing software development ensure that the sMS-500 is
prepared not only for today’s listening environments, but also for the future of network audio.

Support for Roon Ready, DLNA/UPnP, MPD, Squeezelite, HQPlayer NAA, Diretta, Qobuz Connect
and other network audio environments allows seamless integration into a wide range of high-end audio systems.

Engineered for Music

At SOtM, technology has never been the destination. It has always been the means.

Reducing electrical noise. Improving timing accuracy. Preserving every subtle nuance contained within
the original recording.

Every engineering decision is guided by a single purpose:
to bring listeners closer to the music.

That philosophy continues in every aspect of the sMS-500.

The Beginning of a New Generation

The sMS-500 is more than the successor to the sMS-200.

It marks the beginning of a new generation of SOtM network audio products.

Built upon an entirely new hardware architecture while carrying forward the philosophy that has defined
SOtM for years, the sMS-500 represents the next step in the company’s pursuit of musical excellence.

The Next Generation Begins.
