sMS-200ultra Neo PLUS sNH-10G switch mod

  • Sale
  • Regular price $2,300.00

This price includes:

  • the sMS-200ultra with switch modification unit
  • SOtM sNH-10G switch 9Vdc (12V dc optional)
  • labor to enabling the sCLK-EX 1 clock point, and
  • SMB connector installation and cables
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 SOtM sNH-10G Ethernet switch).

What is the modification?

  • Installing SMB connector only to have the clock signal from the  sMS-200ULTRA sCLK-EX clock point

  • Modifying the sMS-200ultra sCLK-EX clock

  • Installing the SMB connector to the sCLK-EX side

  • Installing the SMB connector to the sNH-10G side

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


sMS-200ultra is the newest generation of audio network player with a built-in ‘Media Player Board’ developed by SOtM.

 The sMS-200ultra is similar to the sMS-200, and boasts a dedicated ARM processor board, purpose-built to support only audio. The difference lies in the addition of the upgraded sCLK-EX clock board – in a compact and specially-designed case. The clock is one of the most important factors that determines the sound quality your digital devices, and the inclusion of the clock in this unit will improve your entire system – giving an overall solid performance to your listening experience. This means that you get a custom-built product focused on creating the perfect audio sound performance with strong functionality, with none of the performance problems and deterioration of sound that can occur with ready-made processor boards from other manufacturers.

Player software:  ROON, MPD, DLNA, SqueezeLite and others are available.  You can use your music files from an external USB storage device, network shared folders or streaming services – or easily add even more functions via a software upgrade. Simple and nice looking Web GUI allows users to choose the desired audio function, setup and control playing music file through Apps on users’ smart devices.

sMS-200ultra is the only network player of its kind – delivering high fidelity together with impressive sound at a great price. Immerse yourself in the difference with the sMS-200ultra.

sNH-10G Network Switch

If you thought it wouldn’t be possible to increase your love of music, then think again.

If you are looking for a rich and beautiful sound with your quality audio system, and are passionate about finding the perfect high-end sound with your system, then look no further than the purpose-built sNH-10G Network Switch from SOtM.

SOtM has specifically developed the sNH-10G Network Switch for audio systems – to overcome low performance in a network environment and/or enhance the performance in a functional network environment. It is a product that can fundamentally improve the performance of your network audio system.

Many audiophiles invest a lot of time and money in order to enjoy their passion for audio, but find that it is not easy to overcome and resolve issues with their sound.

This is especially true if you are working with a networked system, but occurs even when operating ultra high-end digital audio systems. Physical network transmission technology has been waiting for a solution.

While there are already a variety of high-end digital audio devices, not all of the physical network connections use techniques developed for audio transmission. This leads to a lack of musical fidelity in high-end audio devices.

The input and output terminals in the sNH-10G consist of eight LAN ports and two SFP ports. There is also an option to install the sCLK-EX (internal clock) and 10 MHz master clock connector to further maximize sound quality.

With these options and high-performance network cables, such as the dCBL-CAT7, your network audio system will be able to realize more realistic textures, a wider sound stage and explosive dynamics – all without losing the detail of the entire range.

The addition of the sNH-10G Network Switch to your high-end network audio device will allow you to experience the ultimate sound of your system.

The switch is beautifully designed, and finished with a luxurious aluminum body, to further differentiate it from other conventional network products.

Experience the difference of the sNH-10G.
