So my new Schiit Floor Wart (Cthulu) is emitting a buzzing sound when it's plugged in. It doesn't matter if its outputs are connected or not. It can be heard from at least 2 meters away and is just loud enough to be annoying. It's not the power outlet because I've tried other outlets. The separate wall warts for my Schiit stack don't make any noise.

Does anyone have a Cthulu that does this? Or has one that is silent? I'm wondering if this is an unfortunate feature (in which case I'll return it) or if its a defective unit (in which case I'll get an exchange).

Thanks.
