@ghdprentice , thanks!
I actually got sucked now (really for no good reason!) into "hardwiring" the ethernet cable through the crawl space. Quite a PITA fishing it through 3 different places, but I figured I already have the cable, have the time, and have the poor judgment (and twisted urge?) to proceed with the challenge....
We may be hearing very slight improvement with our turntable, but definitely none with our Sony ES SACD player over wifi.
Like you, I resisted this, for 10 years in our case ever since we moved here. Again, we have never had an issue or the need to do this. Needless to say, I am not proceeding to invest in an audiophile grade switch... :-)
Cheers!
