I recently bought a used EX and love it via the USB out in to my external DAC. I have no issues at all.
However, I happened to connect up to the internal DAC and used the RCA outs whilst I bought a new DAC. When connected to my amp through the RCA out (and assume to be utilising the internal DAC) I get what I can only describe as electrical interference (jittery) noise coming through my speakers. This noise occurs without anything at all nearby being plugged in, it doesn’t even need the Ethernet connection to be plugged in for the noise to manifest. (I thought the interference may have come from external sources)
When it’s connected via the USB out everything is deathly silent, any ideas what could be causing this noise from the RCA out?
If I could upload a recording of the noise here I would, but don’t see an option.
Any ideas? The dealer I bought it from doesn’t seem to be able to get the fault at their end. It’s strange how it’s only via RCA out though and not USB
