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.

I resolved this problem at the source of noise in my home. I filter the AC blower, AC compressor, microwave oven, all three computers, the refrigerator and every other device that causes me misery.

Expensive you say? Not at all. You can buy good filters for each of the above items for less than one audiophile device.

More importantly these don’t degrade the performance of your sound system. Stopping the noise from entering your stereo is much easier than trying to remove it once it’s already there.

Here is the company I bought my suppressors from:
