I agree with fastfreight
Roon or not? I LOVE Roon and can’t imagine not using it. If I wanted a streamer that wasn’t Roon-capable, I would get an Aurender. Their Conductor app is the best one I have seen that isn’t Roon. FWIW, Robert Harley has used the top Aurender in his reference system for years.
I have been very happy with my Small Green Computer sonictransporter Roon server, used with a Sonore microRendu streamer endpoint into my DAC. I have 2GB onboard storage for my ripped files. It was a better value than a Roon Nucleus (less $$, better support).
