"Is it that good? Yes it is"
An excellent review of the SOtM sMS-200. Hans Beekhuyzen compared it with the highly rated microRendu using the same model power supply, and commented "right away the microRendu was over taken by the SOtM." Other notable comments - "better while the price is lower", "the sound is even more relaxed and open in the mid range and also the lows are better controlled"
Note: We will have the mentioned sBooster power supply soon! As well there is the compatible SOtM mBPS-d2s power supply - a unique and smart dual-cell battery supply that completely eliminates any down-time due to a flat battery.
