Help optimizing my streaming setup

In my experience, the degree of improvements one hear from these noise filtering devices are in direct correlation of your components downstream. Since you asked, I don’t think most Ethernet switches under $1K ‘designed’ for audio yield noticeable improvements if used in conjunction with ENO passive filter. In a setup like yours, ENO should be more than adequate. If I were in your position, I would order ENO Filter and any of the aforementioned devices off Amazon and compare it in your system. And I wouldn’t bother with LPS on your Fios router if you’re using a filter like ENO ahead of N100SC.

If I may inquire. what type of power cords being used with N100 and BP DAC? 

Thanks, @lalitk.  I appreciate your and everyone else's advice! 

The power cord on the Aurender in an AQ NRG-Y3 and the one on the DAC is a factory-style one, albeit very beefy.  I have a few Oyaide Black Mambas that I can try on any of the components.

I would try the Oyaide Black Mambas on both components and access any improvements. If they Oyaide’s been dormant, allow break-in for atleast 24 hours. 

Yes to a ethernet filter like the ENO or SOtM dcbl.

Yes to the EtherRegen using it as a "Moat".  The ER is better with a good LPS and a better clock.  The clock needs a good LPS also.

Managing AC noise with something like an Akiko Corelli and ground noise with something like a CAD GC1 will give you a blacker background.

As far as a (potential) single cable upgrade, wondering about this one. Grounded on the router (switch) side. Wondering how this would compare to a galvanic device?
