sMS-200ultra with sPS-500 PLUS Free modded switch

  • Sale
  • Regular price $1,700.00

This price includes:

  • sMS-200ultra 
  • sPS-500 with standard copper dc cable
  • D-Link 5 Port Gigabit DGS-105 Ethernet Network Switch
  • labor to enable the sCLK-EX 1 clock point, and
  • SMB connector installation and cables
  • Free shipping in USA

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 2 x 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.

 About the sMS-200ultra Special Edition

For audiophiles who are looking for the best sound quality with their sMS-200ultra, the sMS-200ultra Crux Audio Special Edition further upgrades this fantastic network player with the addition of eABS-200 EMI absorber sheet (eliminating EMI noise) and replacing internal wires with silver wires.

The sMS-200ultra Crux Audio Special Edition already includes 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 these upgrades 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.

Impress yourself with truly beautiful music.

About sPS-500

The resolution, textures, transparency and expression of sound is greatly affected by how and what power is supplied to your audio device. A power supply unit affects the quality of the entire audio system, and should never be considered as “just a power supply unit.”

The sPS-500 is an audio power supply designed specifically for high performance audio. It is built to eliminate noise generated by powered devices as well as to simply remove noise coming from an AC power source.

Using SOtM's unique technologies for noise cancellation and sound enhancement, and high quality audio components that are already proven in sound quality, you will hear superior sound improvement with the well-designed sPS-500.

The sPS-500 can easily cope with a wide range of AC power input – the output voltage can change to 7Vdc, 9Vdc, 12Vdc or 19Vdc depending on the power specification of your audio equipment – and the 50W output is flexible enough to be applied to various audio systems. It is also designed to provide more stable power through the input, output, overcurrent and overheat protection circuits.

The rich texture and detailed, luxurious sound created with the technology of the new sPS-500 will create a new listening experience with your audio system. A unique and impressive exterior design also makes the sPS-500 stand out from the crowd. The sPS-500 will help bring your audio system up to the next level.
