Unidentifiable popping sound

Not 100% sure it goes in this forum — apologies if there is a better place.

For 6 months now, something in my system is making a clicking/popping sound. It usually happens 15 minutes after I power things up, or about 10 minutes after I power them down. It can also happen spontaneously when everything is technically on standby. I actually have a recording of it, but not sure how to upload here. Any ideas?

Preamp — Nagra Jazz (possible) (it happened with both old and brand new tubes)
Amp — Nagra Classic Amp (possible)
DAC/Source — PS Audio Directstream (possible)
Phono stage — Pure Audio LV-1 (probably not)
TT — Clearaudio Concept (definitely not that)
Cables — Luna Orange (also, definitely not that)

I had this problem with my PS Audio Directstream dac when using the bridge.  PS Audio was very helpful and sent me special firmware updates and a new bridge to try but the popping continued.  Finally, they took back the bridge.  Things sound very good even without it.

I don't know if there's a way for you to send me the recording.  Maybe someone else knows about this.  
 

I do have two suggestions.  If you're using the bridge, try removing it and see if the ticks go away.  Also, try calling PS Audio customer service.  I dealt with TJ a couple of years ago and he was very helpful.  As I mentioned previously, he sent me a replacement bridge to try as well as some beta software.  Unfortunately, none of those things fixed the tick problem so I returned the bridge for a refund.  We never did figure out the cause but I'm very happy with the sound absent the bridge and there are no ticks..
