So if I am digesting this correctly. If the NAS is running amiss it has a direct correlation with Roon processing in the most effective fashion? I'm sure this has been covered; Any optimal suggestion as to NAS integration? Roon is going to see the NAS in the network no matter what, unless its disabled as you have done.
Please share with us your results when and if you reintroduce a properly functioning NAS. It "sounds" as though in your network the Olympus/Roon SQ may have improved more so after disabling the NAS.
I hope your making big strides in the "garage project" sounds like an album cover....
Well it shouldn’t, but if it’s malfunctioning and Roon tries to access it but either can’t, or gets time outs/errors, and will likely just keep trying, I could see that impacting SQ. Errors are high priority events which can interfere with the playback processes.
