Not a bad suggestion!Clicking? I can definitely say there's ZERO clicking of any description on my device. Maybe WiFi or EMI interference? Too close to the phone or powerful WiFi/microwave devices? That will often result in clicking/hum on some devices.
Although I've heard examples of WiFi/microwave RFI and this wasn't consistent with that. I'll also note that I do have very good WiFi coverage throughout my house (by design), but I also expect that my AV equipment will be well shielded against such interference. Although building a Faraday cage around my listening room is an amusing idea
By training I'm an EE, but I went into SW and it's been quite a while since I've actually worked on hardware. That said, the noise is close to what I would sometimes encounter when digital and analog circuits are mixed together without proper noise control measures on the circuit board. It had a steady cadence (about every 2 seconds), possibly suggesting something related to the clock (or a subdivision of the clock) or at least synchronized to it. Anything involving the DAC circuit would certainly qualify.
Since many folks seem to have good units, maybe I have some bad caps on the circuit board. Some bad noise suppression caps would not necessarily interfere with QC tests unless they were specifically testing the noise floor.
