The sMS-200 is a new generation of mini network player with built in ‘Media Player Board’ developed with our own technology.

 The significance of the sMS-200 comes from the dedicated ARM processor board developed specifically for audio. It is not like the many ready-made processor boards in the market offered with dazzling low price but not very high sound quality, due to which many audio product manufacturers experience deterioration of sound and are forced to use unnecessary features from their boards. Not so with the sMS-200.

 SOtM developed this with audio sound performance at the forefront, getting rid of all unnecessary features and concentrating on a high quality sound tone for a reasonable price.
 The sMS-200 is carefully designed to provide the best sound quality based on our own unique technologies built up since the days of media players, and it is probably the only one capable of exceeding the current network players on the market in terms of functionality.

 As to the player software, Roon Ready, MPD, DLNA, SqueezeLite and others are available as well as music files from an external USB storage device, network shared folders and streaming. And more functions can be easily added via software upgrade.

 The sMS-200 is the one and only network player in this price range that delivers high fidelity together with impressive sound. It makes people freely imagine the real scene where the original sound was generated.

 Experience the difference and surprise with the sMS-200 developed by SOtM.

sMS-200 Neo

 The sMS-200 Neo is the updated model to our previously very successful sMS-200. While the original model sounded very neutral and balanced, the changes brought about by the updated sMS-200 Neo will mostly be perceived as a more relaxed presentation. Although the standard sMS-200 is already an overachiever, the sMS-200 Neo retains this while still adding an extra dose of musicality to the party.

We have the most special and unique original technology made by our own such as Ultra low noise regulator, Ultra low jitter clock, active noise canceler, multi stage regulation and the other leading edge original technology, these have been proved by tX-USB, tX-USBexp, SATA Filter and etc from the moment when they revealed in this industry and they can’t be easily copied nor reproduced by others. These are applied to all our products, and they present the most detailed and high quality sound and it is the key feature that why our products are different with others.

As it has been mentioned above, the most special and unique technologies have been applied to all SOtM products as well as the sMS-200. It make sMS-200 presenting the most attractive sound quality compared to others in the same price range products on the market, actually we sure that there is no one in the same price range with such high quality audio product in current market.

Yes, sMS-200 supports Gigabit Ethernet but Our initial sMS-200 batch was released in the condition of supporting 100Mbps network, but now sMS-200 is available to support Gigabit Ethernet by upgrading some parts of hardware and software.

 The initial batch includes the serial number from MP0001 to MP00055 and SP0000 to SP0008. You can check the serial number of your unit and apply the new upgrade as following the instruction.


Also if your unit has the serial number, MP00012 and  MP01001 to MP01030 with  the software version 0.1.8 below, please apply this instruction. Also please check the router or switching hub is supporting Gigabit Ethernet.

  • If you have the Gigabit Ethernet supportive router or switching hub,

-> Connect sMS-200 to the gigabit Ethernet supportive router or switching hub and then upgrade sMS-200 to the latest software through Eunhasu animated GUI.

  • If you don’t have Gigabit Ethernet supportive router or switching hub,

->  Please follow the instruction in the link.


 For a stable network connection, we recommend using a gigabit speedy router and above CAT6 Ethernet cable, and we proudly and strongly recommend the dCBL-CAT7, iSO-CAT6 or dCBL-CAT6 in such network audio system

  Also, the dedicated USB audio device as like sHP-100 or sDP-1000EX can present most detailed, high textured sound and high resolution with sMS-200. And to enhance the quality on USB output, we recommend using tX-USBhubEX together with sMS-200, then you will be able to hear  the upgraded and improved sound quality .

Just in case, the external USB storage is detected in LMS web interface as USB1 or USB2 but if you can’t find the music file, go to LMS Settings -> Basic settings tab  -> Rescan Media Folders and click Apply. And then the music file will be shown and able to play.

If still having the problem after you apply the above method, please stop and start Squeezelite function on Eunhasu Web GUI.

Thank you.
