Network Switches

RenoLabs Ultimate Switch, built in LPS, OXCO clock.

Not familiar with that Switch. 
To answer your question, ideally you would want to try another, more expensive Switch, with no-risk return policy. 

Great advice from @thyname, that’s the only way to know what a high end (expensive) switch brings to the party! 

Well, at present I have switch playing 24/7, and I'll try one of my power cords that fit sound signature I'm looking for. Burn in and pc issues will be moot at that point. $3500 for Innuos a little steep for me. Uptone switch would be next try, the only reason didn't purchase is only one highest quality output, I need two, one for server, other for NAS.

RenoLabs switch has amazing build quality, would fit $3k plus category. It may also be the switch is exposing something else in streaming setup. I'm presently using SOTM SMS200Neo in series with Uptone USB regen, perhaps using two usb decrapifiers is excessive, may try removing Uptone. Both on LPS, Sotm on Uptone JS2

The only way to know how Reno switch ($650) stacks against Innuos switch is by trying it in your system. Otherwise, it just a pure speculation on your part. Going from Reno to Uptone may yield ‘lateral’ improvements or different flavor, if any. I say this from my experience by trying switches, filters priced under $1K in my system.

I am way passed some of these short term bandaid solutions :-)
