Interesting choice of PSU! I have been looking at lab power supplies to power audio equipment, but the top ones are very expensive. I like the idea of going directly to the pcb without connectors too. Might need to try that as well. I like my 218 also because you can control it with an app, giving the whole system a modern feel.

On the roon implementation: I have heard improvements from moving the core to a separate machine, but never any impact on where the core is in the network. Also the PSU doesn't seem to matter. I have a LPS on it for peace of mind, but could not tell the difference.

Curious what your final verdict is between the 818v3 and 218 LPS for roon via speakerlink.
