My best guess is local files are not processed by the Dela (if you play local files Dela is only doing network isolation)

Correct, the fibre is isolating and the switch facilitates some traffic for roon control.

@clive101

vs streaming the Dela may be do some processing with its clock and affecting the sound.

Here is an explanation of what a better clock does to ethernet data …

Audiophile network switches

As I understand it all switches receive data transmissions, store the data packets (while working out where to send it and waiting to send it), and then sent the data in a transmitted analog signal, so they have: clocks, to govern the frequency of transmission of data packets, but they don’t reclock (like the K50 reclocker that outputs a ‘stream’ of data) RAM/memory to store data before sending. The intent of a ‘better’ clock is to reduce phase noise of the transmission of data packets…

If you are feeling brave you could exchange the router with a 10G/SFP+ router which should have much lower jitter and noise. I use Mikrotik CRS 305 because it accepts 12v DC input. Then you could use fibre direct from router to Dela (and possibly use better SFP modules) and also fibre from router to your existing switch to isolate all that from the router.

Recently with a K50 in my headphone system I had a good result by adding a Chord Mscaler

Interesting, a few possibilities there. Was that with usb input to M Scaler? Was M Scaler upscaling? Was that single or dual output to Dave?

Finally, try removing the disks from the Oladra to remove its affect from the equation.
