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.

Good post crm.

@OP,
Is the hum occurring only with Tidal?

No, the hum is constantly on. I lowered the volume of the Node and it's still there.  I tried all of the cables that came with the Node, unfortunately a digital cable didn't come with and I don't have an extra. I'd like to use the RCA's to hear the difference between the two DAC's.
I've changed outlets again and tried a cheater plug, to no avail. Not sure what else to do here. 
Not really my forte, but how would I attached a ground wire between the Node & the KEF's?

Try taking a scrap piece of speaker wire and touch one end to a metal chassis screw on the Node and the other end to metal chassis screw on the KEF. If that eliminates the hum you’ve got your solution, make it more permanent and you’re good to go. Just make sure you’re bonding metal chassis to metal chassis. Screw heads are a good starting point as they are generally unpainted and therefore good conductors.

Thanks. I finally reached Bluesound support and they suggested doing a factory reset of the speakers and the Node. It worked. Thanks for the tips though.

@skoorb824 ,
Great to hear. A factory reset would be the last thing I would think of doing, in your situation.
