Bluesound Node 2i & KEF LS50 wireless hum/buzz


Hi - 
I recently purchased a BS Node 2i to connect to KEF LS50 wireless speakers. I keep receiving a hum/buzz when playing through Tidal. Has anyone else has this problem?
I have the BS connected via RCA in order to use the DAC in the BS. I've changed interconnects, power cords, outlets, used a Furman power conditioner, just a wall socket, all plugged in the same socket, etc..., and nothing seems to work. 
Bluesound support is a joke. No phone number and I've sent emails roughly a week ago with no response. The outlets in the room were all installed last year and are all grounded. Any help would be appreciated.

Hi there, @skoorb824 did you ever figure this out? I was thinking of going after the same set up. 
Solution. Connect your KEF speakers to your BS node by Bluetooth. I have done this and it works a treat. It is not the NS node it is the KEF speakers. I had the same setup and the same problem. I tried a different input (Echo Dot) and encountered the same hum. The workaround it to connect by Bluetooth using the both the BS app and the KEF app, it is a simple Bluetooth setup. 
Hope this helps
Hello Shifuman, question: how do you connect the KEF (LS50 II wireless) to the Vault or Node 2i? I tried but didn’t succeed ... thanks!
