I decided against the Nucleus, because it’s not easy getting human support. I got a Small Green Computer Sonictransporter Roon server instead, and it’s been excellent (and Andrew has offered excellent tech support when needed). I paired mine with a MicroRendu streamer into my DAC. Not sure they sell the Micro, and maybe only the UltraRendu now.
