@dgarretson That sounds like an amazing setup.
@plga What was your final decision? I am in the same boat as you. I bought the SOtM sMS-200 ultra Neo 2 years ago with no clock input. I am considering adding a 10 MHz external master clock which means I need to replace the Ultra Neo and buy a DAC with clock input. I am also looking at the Gustard R26 streamer / DAC as well.
