Crux Audio is pleased to announce that preorders are now available for much anticipated SOtM sMS-200ultra and the sPS-500.

The sMS-200ultra is an upgraded version of the popular sMS-200, and includes the new low-noise, low-jitter sCLK-EX2425 clock, housed in a new, slightly larger chassis. Key features include:

  • Ultra low phase noise custom design oscillation circuit
  • Wide operating voltage input range
  • Ultra low noise +5V output for system operation : 0.5A max
Starting price without master clock connector enabled is $1200. The cost is $1400 with enabled master clock connector. The regular sMS-200 will continue to be available.

The sMS-200ultra fits nicely into the suite of affordable hifi products produced by SOtM, and provides additional choice in improving the sound of a system.

The sPS-500 (at $500) is the new linear power supply that complements the sMS-200 and sMS-200ultra. It replaces the battery powered mBPS-2dS, which has been discontinued. Additional information and specifications for both of these new products can be found at

Preordering is now available. The expected shipping date will be after 31 May 2017, and orders will be filled in the order they are received. Please contact us if you have any questions.
