bonepeeler and Moderator Dude,
Nice to hear that recording!
This is exactly the sound I get once in a while from my right side TRef subwoofers (haven't noticed if it's the upper, lower, or both). After a lot of experimentation, I am 99% sure this is wifi interference noise. This only showed up after I upgraded my TV and wifi network to Google Wifi, and I have a wireless node located on the wall about 5 feet from that speaker. It is not practical to move it (it would end up being closer to the left speaker), and it only shows up once in a long while. It has not gotten worse. It is more pronounced (temporarily) after I restart the entire system after a total cold shutdown. Most of the time it's not there at all.
To troubleshoot, I tried several things independently: disconnecting the power line at the speaker (I could still hear it during the grace period before shutdown), powering off the amp, disconnecting the speaker cables, disconnecting power to the nearby Sony Bravia TV (running wireless), and even shutting down the wireless node. None of these helped (the last was a surprise). I now suspect it's my Auralic G2 streamer yelling at the wireless node, or perhaps another node in the house. Or a ghost.
I've read several discussions on this forum of what sounds like the same problem. It sounds as though there's a pathway into the speaker sub amp for wifi noise. If so, maybe GoldenEar could look at doing some testing with an eye to getting better shielding (or whatever) in future designs to eliminate the problem.
