Hi Eric,
Thank you for your help. Here you go. Let me know what else you might need.
Basic star topology.
The mac mini is cabled into the NETGEAR ProSAFE
The synology is likewise cabled into the NETGEAR ProSAFE
They sit a few feet apart.
The Benchmark DAC is wired directly to the mac, which is wired to the amplification, as neither of these need the network.
Roon core server sits on the Mini.
Roon app sits on another mac and ipad that connects wirelessly over a UniFi wireless network.
The connection of core server to app is made wirelessly through the network.
All UniFi endpoints are usb wired from the central controller.
There are no repeaters or extenders in the audio part of this system as they are not needed for audio here.
There is powerline conditioning, separate circuits, power outlets etc.
Mounted through Roon.
Provided Roon a network path: smb://…to main music repo, username and password in settings.
