About the sMS-200ultra
The sMS-200ultra is an upgraded network player equipped with a dedicated media player board and a high performance audio clock, born from SOtM's years of experience.
Improving upon the great reviews and user feedback on the sMS-200, the sMS-200ultra has been designed to include the sCLK-EX clock — the heart of this superior digital audio equipment. This new combination brings dramatic sound improvement. If you’ve been enjoying the great performance of the sMS-200, the addition of the sCLK-EX will enhance your experience beyond the usual sound limitations of traditional small source devices.
Use the master clock connector option to sync the sMS-200ultra with an external master clock device such as a Rubidium clock. This feature has the potential to redefine your perception of sound from small network players.
The sMS-200ultra is a digital technology device but, because it is based on SOtM’s deep understanding of analog technology, it can be defined as one of the few high-performance digital audio devices that performs superior analog sound.
With cutting edge technology providing the newly adapted heart to the sMS-200, the sMS-200ultra is born. Impress yourself with truly beautiful music.
