I haven't yet but will be trying in within the next 30 days. I will first focus on Roon and HQPlayer convolving 6 channels and the look into SBT. From what I've seen it should work well.
Roon and Squeezebox
I read Roon can be used instead of Logitech Media Server to stream to Squeezebox devices. Anyone doing that? How is it working out?
