sMS-200ultra + Ethernet switch mod

Regular price $2,190.00 AUD

Please note that SOtM expects to ship to us on June 19, and we will send them out as soon as we receive them!

This price includes:

  • the sMS-200ultra with a switch modification unit
  • D-Link 5 Port Gigabit DGS-105 Ethernet switch
  • cost of shipping the switch back and forth to SOtM
  • labor to enabling the sCLK-EX 1 clock point, and
  • SMB connector installation

Please allow additional time for the mod.

Why should you modify?

  • The sMS-200ultra has the sCLK-EX clock with 4 points. The sCLK-EX can be used for all digital devices that require clock signals such as DAC, USB host card, CD player, PC main board and LAN controller.
  • Two points are used by the system internally (sCLK-EX2425) and two points left free to clock other digital devices (eg Ethernet switch).

What is the modification?

  • Enable one point (clock)
  • Replacing regulators in the Ethernet switch
  • Replacing the capacitors in the Ethernet switch
  • Add SMB connection (coaxial RF connectors)

This modification works to eliminate noise coming from the Ethernet connection and improves/cleans the sound as a result.


 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.
