I have been doing this for at least 20 years in an analog way. Using a stereo system, you can make a change in one channel (for example: a power cord if you have monoblocks) and, while playing a mono signal, listen with a speaker, earphones, or a meter across the hot terminals of the power amp. Before installing the change you must adjust the gains to match, and sometimes tweeking the frequency response will yield a better null. This method allows you to test using an actual music signal instead of a test tone. Easy to do. Try it with your $2000 power cord, and weep.

I have to revive this from the dead. The quoted statement was so funny. It's worth sharing.
