Blanket statement? I’ll bet only 2% of these posters are able to test an Ethernet interface or an i2s interface.
My Aurender is optimized for usb! If I had a $ for everytime I’ve heard that, I’d be rich. Years ago, I bought the top of the line Auralic over the Aurender and Lumin. And guess what, it was optimized for usb with femto clocks and that was feeding the best wyred 4 sound dac with the best aq diamond usb cable. I also had the gimmicks/tweaks like reclockers/etc that were optimized for usb.
I got rid of all that crap, got 1 of the best dacs available, used Ethernet, and the sound was much better, much much better.
Then a couple months ago bought the streamer with only an i2s and coax output so I can use i2s, another big improvement.
There is a reason the best dacs don’t have usb or have i2s and Ethernet interfaces.
