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.

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!
