New Bluesound's Node 2i

In my case with the 2i, the wired connection sounded incredibly better than the wireless connection. If you have ethernet cable long enough to reach upstairs, it might be worth it to just run the cable on the floor to test the sound.

an ethernet extender that uses you household electrical wiring
plug ethernet into ethernet receptacle into unused electrical outlet
then for termination take the same setup and plug into 2i ethernet input from electrical wall outlet 

you are still using wifi, or is it the wired connection to the unit that matters?

My guess is that its the wired input into the unit vs using the unit's wifi adapter which improves the sound. I would think there is electrical noise associated with the wifi module.
