Topic: Adi dac 2 fs high frequency noise from unit
Received one of these for Christmas and absolutely love it. However, I've noticed there's a high frequency noise coming from the unit upon started up, after the clicking sequence has finished. Not sure if this is an issue and it's only really noticeable if I put my ear close to the unit. Connecting the unit via usb to my macbook pro seems to make the noise more high pitched but it's there regardless of whether connected to usb or not.
I've seen other threads discussing something similar but those did not directly apply to my situation. Is it a ground loop?
Any help is welcome.
