I compared a couple of wi-fi set ups from 1, 5,10 feet to the Node 130, and direct cabling with a 1 meter ethernet cable I had laying around.....there was a definite audible benefit to going wired direct. Even more noticeable was upgrading the cable to a Supra Audio Cat 8 and/or an Audioquest Vodka ethernet cable.
Do I care that there is no technological reason for that to be true? No.
