Help optimizing my streaming setup


My streaming setup is pretty simple and sounds very good right now, but I'm wondering if I can do anything between the router and the streamer to make it better.  I'm not interested in a DAC upgrade at this time.  My virtual system is not up to date.  The system is:

Verizon FIOS router>6 meter DH Labs Reunion Cat 8 ethernet cable>Aurender N100SC>Oyaide DR-510 spdif>DAC

Since I'm able to hardwire the streamer to the router, would a switch provide any benefit?  I'm aware of the Eno that some of you guys seem to like and have been looking into them.  Would an LPS for the router do anything?  Is there anything else I can do?

Contact small green computer ,the Sonore products are excellent I just bough5 the Ethernet to fiber optic deluxe modules , you buy them ,decent linear power supplies 

and from the router, much  cleaner for noise cannot travel over-fiber optic .

If you have Cat 8 Ethernet cable connecting your router and streamer, don’t use any galvanic isolators like EverStar MI-300, cause using it will depreciate protective porpoise of Cat 8 or Cat 7 cable Shilling. Any shielded cable connecting the ground plane between devices and braking up the shilling by galvanic isolator can cause noise.

UpTone Audio etherregen goes between hardwire ethernet from router before the streamer.  $640 Audible Improvement.
