Connecting a streamer via an Ethernet cable

I am using a wifi extender, connected to an EtherRegen Switch, connected via Ethernet to my Aurender WE20se. My audio guy recommended this when I got rid of my streamer that connected directly to wifi (Auralic Aries G2). I’d be interested in knowing if someone has done a critical comparison. I cannot tell the difference between an album stored on the drive of the streamer with one streamed via Qubuz. While it seems hard for me the direct connect could improve the sound, I long ago learned that is virtually never true.

I'm interested in your experience but having trouble understanding that last sentence.  Perhaps a typo?  Would you mind explaining further??THANKS.

My experience is yes. I had a Bluesound Node 2i and initially used it with wifi. I ran an ethernet cable to a switch in my music room and the sound did indeed improve. Now I'm using a Lumin streamer with no provision for wifi, so still using the ethernet cable.
