Everything is up and running - sounds splendid!
I’m now using the sMS-200 with an sBooster power supply (12 to 13.2v) and the Sonic Transporter i5 for the Roon Core, and the sMS-200 feeds into a Mytek Brooklyn DAC/pre-amp. It all sounds very, very good. I’m listening to Roon/Tidal (MQA, as well) all the time and the musical variety is endless and the quality of the streaming sound is quite remarkable. I find many streamed recordings indistinguishable from the CD versions that I own.
