SOtM Introduces Three New Products - sMS-500, sPS-550, and sCLK-OCX10ultra

SOtM introduce three new products designed to advance high-end digital audio performance - the sMS-500 next-generation network music player, the sPS-550 high-performance power supply, and the sCLK-OCX10ultra master clock generator. Each product addresses a fundamental aspect of digital audio - music playback, power quality, or clock precision. Together, they reflect SOtM’s ongoing commitment to developing technologies that preserve signal integrity, minimize unwanted electrical noise, and bring listeners closer to the music.

SOtM sMS-500. A New Generation of Network Audio

The sMS-500 marks the beginning of a new generation of SOtM network audio products. More than an upgrade to the acclaimed sMS-200 series, it features an entirely new hardware architecture redesigned from the motherboard upward. SOtM’s Eunhasu operating system has also been optimized for the new platform to provide stable operation and flexible support for modern network audio applications. The sMS-500 supports a wide range of playback environments, including Roon Ready, UPnP/DLNA, MPD, Diretta Host and Target, Qobuz Connect, HQPlayer Embedded, and HQPlayer NAA. Combined with a dedicated audio-grade USB output, it offers a versatile foundation for high-end digital audio systems.

SOtM sPS-550. Clean, Stable Power for High-End Audio

The sPS-550 is a high-performance power supply developed to provide clean, stable power for digital audio and computer-based audio systems. Using SOtM’s proprietary power supply design and carefully selected audio-grade components, the sPS-550 is engineered to suppress both noise entering from the AC power source and unwanted electrical noise generated by connected equipment. With eight selectable DC output voltages - 5V, 7V, 9V, 10V, 12V, 15V, 17V, and 19V - and maximum output power of 80W, the sPS-550 supports a broad range of compatible components. Built-in protection against over-current, over- temperature, and output short circuits further supports reliable operation. Designed to complement products such as the sMS-500, sMS-2000, and sNH-10G, the sPS-550 provides a robust power foundation for carefully integrated high-end audio systems.

SOtM sCLK-OCX10ultra. Precision Clocking for Digital Audio

The sCLK-OCX10ultra is SOtM’s next-generation master clock generator, designed to provide a precise 10MHz reference signal for compatible digital audio equipment. Compared with the sCLK-OCX10, the sCLK-OCX10ultra achieves an approximately 5dB improvement in phase noise in the low-frequency region around 10Hz. Its proprietary analog circuit design generates a clean 10.000MHz sine-wave clock signal, while the internal oscillator features typical phase noise of -145dBc/Hz at 10Hz and temperature stability of ±5ppb. The unit also features ten independently isolated BNC clock outputs, allowing multiple compatible devices to share a common reference clock while minimizing unwanted interference between connected components. This combination of improved phase-noise performance, precise clock generation, and extensive output connectivity makes the sCLK-OCX10ultra a powerful solution for complex high-end digital audio systems.
