OK, you convinced me Emile -- no trying to "make one size fit all" by having the Roon core on the Extreme available to the rest of my home network.The last piece of the puzzle is how to power the AP without compromising SQ.
But using a dedicated AP is simply (far) superior to any of the other solutions I tried.
I understand the desire for convenience, alternative solutions, multiple Roon Endpoints, adding more devices etc, but I cannot imagine you’d want to compromise this new level of SQ once heard. Going back to “just the switch+network card” would require me to not listen to the system for a few weeks to recalibrate as that now suddenly sounds pretty dull. Adding devices, routing more traffic, it all has an impact.
The last thing left to do is to properly filter/power the AP, which nut I’m very confident on we can crack.
So now I have to consider what to use to run Roon on the "dirty side" of my home LAN.
I have a Mac Mini with the full Uptone Audio fan and power mods and which boots off of an industrial-grade SD card, but that requires the JS-2 LPS which I am currently using to power the Taiko switch (and I plan to continue using to power the Taiko router, too when it gets here). I have an idle Sonore Signature LPS but it is 7 VDC, which I believe is too low for the Taiko switch though I think I recall Emile saying 7 VDC was OK for the Router.
When I loaded my library onto the Extreme I had hoped to keep my several NAS powered down except for back up activity since I didn't need to run my library from one, but the NAS' and all the computer/networking stuff other than the Taiko switch are all on a different circuit, so I guess it won't hurt to run one of the NAS again.
I guess I need to figure out what is a cost-effective Roon-core platform for my wife's use on the non-audio part of the network.
