I had this exact problem. For me, it was a bad tube in the right side of my phono stage, plus a different tonearm cable. It was all phono related for me. Not sure if that applies in your case.
I have dedicated lines, but why is this happening?
When my central air kicks on, I hear a pop through each speaker.
Now the odd part is, I just started hearing this recently. I never remember hearing it for the first several months after I had the dedicated lines installed.
I have made several changes to my system recently that has taken the transparency of my system to a level I didn't think was possible, but I don't think that could explain why I am just now hearing the pops. Or could it?
But the primary question remains. Why is the air conditioning popping through my speakers when I have dedicated lines.
Could this be coming back through the main bus bar ground in my panel?
What would fix it?
I obviously know crap about this stuff.
