Routers/Ethernet Switch

Curious as to whether an "Audiophile" grade router and/or an ethernet switch would make a significant
impact on sound quality.
I'm currently running my ISP-Verizon router bridged to an Apple Airport extreme(firmware still updates)
then from Apple router via ethernet cable to my Aurender streamer/music server.
Honestly it seems to sound quite good, but I'm curious if I updated to a new router with perhaps 
a hi-grade ethernet switch-would a sonic change jump off the page so to speak.
Other side of the audio coin is of course--if it sounds good it is good-don't fix what's not broken

Be curious as to your thoughts--Many Thanks
