I do have a dedicated line running to my stereo. When we remodeled the house I made sure that one was put in. Everything important is plugged into a Shunyata Venom 16 power conditioner which has plugs for digital, so the digital equipment is separated from the other equipment.
I think it's worth $100 to give it a try. In layman's terms, it seems as though the handshake between the iPad and Meitner is momentarily failing. I'll put the battery backup, which is made for backing up routers and computer equipment, in tomorrow. The drop-offs have become very rare, but I did notice that two times they happened when something drew on the power. I no longer have drop-offs in the cuts you and I talked about earlier. So, something has definitely been fixed with the Eero mesh system.
