Basic Digital Audio Setup Advice


Greetings! Looking for some feedback on a wired digital audio setup. My primary goal is to play hi-res (up to 24/192) lossless files bit perfectly in a plug and play fashion.

Here's my current (modest) arrangement, my iMac is too far from the DAC to hard wire, forcing use of Airplay and downsampling to 16-44.1...

2014 iMac w/ external HDD (~4TB of FLAC/ALAC files) > Audirvana 3.5/Roon (both on trial currently, migrating from iTunes/Music) > Airplay (via Airport Express) optical > Cambridge Audio DACMagic Plus > Rega Brio > Q Acoustics 3050i
I'd like to add a server/streamer next to the DAC that I can access remotely to take the iMac out of the chain. Initially was looking at a headless 2012 MacMini >  DAC using Audirvana/Roon but I know not truly dedicated to audio.

When going down the Roon rabbit hole I was intrigued by the Nucleus in place of the Mini. I would likely look to move the file storage to a 2-4 bay NAS accessed by either the Mini or Nucleus.

It feels a bit askew to spend more money on the server/storage than I'm into for the DAC/Receiver/Speakers but the ease and cleanliness of the Nucleus has a lot of appeal.

Are there any simpler/less expensive options I'm overlooking that might help me accomplish my playback goals, keeping in mind my audio component level? I'm not very keen on having to assemble so the NUC/ROCK option isn't something I've considered. I also looked at the Bluesound Node2i but feedback on the OS is poor and sounds like some challenges with being actually Roon Ready.

Thanks much!

@gelle yeah, i intend to connect whatever server or computer i use (as well as a NAS) directly with ethernet via the switch. that should do the trick, right?
@dbphd I do use Google Mesh WiFi for my network. Unfortunately the iMac is still too far to connect to Ethernet and honestly is terribly slow in it's old age. If the core runs on it without an Ethernet connection I'm pretty sure I'll still be dealing with a downsampled stream to the end point? my plan was to add an unmanaged switch to the google WiFi to connect the server and a NAS, should i decide to add that. your concerns on special-purpose devices does make sense though. wonder if a Innuos Zen Mini MK3 might be a better option than the Nucleus as it may a bit more versatile?
Thanks for the feedback all, keep it coming!
@gelle the google wifi only has one LAN connection. planned to run that into a switch and then connect the nucleus and NAS. if that wouldn't work, any other options other than a different router?
If I continue to run the Roon Core on my iMac but it is connected to the network via WiFi (not Ethernet), will the signal sent to a Roon Ready endpoint be bit perfect? Unclear as to the integrity of the signal being sent to the endpoint over WiFi. The files would be connected to the iMac on an external HDD.
@dbphd isn't the master google mesh unit the actual router? i believe you're suggesting the access points (additional units) actually function as hardwired ethernet extensions, which may be true. they do have LAN ports that you can connect to other devices. is the mini running the roon core on your network via ethernet or wifi? thanks!
