That Teddy LPS is a funny story 
If your Roon server is not connected directly to your streamer or DAC, then it is connect to your network.
Therefore, there is no difference in terms of sound between a nice Intel NUC, a Nucleus, a MacMini or a PC. It’s just a server somewhere in your network.
It is that simple. And it makes perfect sense. There is no technical reason I am aware of that would lead me to think otherwise.
But… I’m not a stubborn person.
I read some interesting comments about networked Roon servers that would benefit from an LPS.
So I did a pretty expensive experiment. I bought a $500 linear power supply to power my already very expensive Roon server.
Result : not the slightest difference.
I now have a nice NUC with an expensive and useless power supply 
It was a $500 fail
Of course, this is just my own experience, YMMV.
