A pop is noise. Generally many RFI/EMC/EMI engineers are bald. Itís not an accident. These are some of the more challenging anomalies.
Generally a pop can come through an inferior power supply. Or is a current passing through the inputs.
Appreciate this example. A ground loop. A connects to B connects to C. Noise is an electric current. That means a loop must exist. Noise loop might be through A, B, then C. And back to A. The defect that completes that loop might be C. But disconnect A and the noise stops. Many will quickly assume A created the noise.
One path that can be part of the loop is safety ground (the third prong). You can use a cheater plug (a three to two prong adaptor) to temporary break that loop. But that is only to find parts of the loop path; not an acceptable solution.
If the power supply is inferior, then a UPS in battery backup mode might also create noise that would pass through the supply. Power the speakers from a UPS with its power cord disconnected from a wall receptacle. Learn how good that speaker's power supply is.
A pop generated by other appliances should not be heard. However, the solution to eliminating excessive noise is best implemented at the noise generator.
