I use a cable to my iPad. The WiFi signal to my audio room is weak so hopefully that makes the rf weak as well.I did that for last 2 years as I could not listen with wifi access point in any place in my system.
This works excellent.
I was able to bring down the noise to the hardwire connection level with use of 2 and recently 3 isolating switches And powering the AP with a battery.
Kris, is your current set with WiFi and filtering switches sonically better than your prior Lan cable to iPad?
