Hi, Rod:
The most confounding thing about it is that it only distorts when it feels like it. It doesn't do so at any set times such as when it's first turned on, when I crank the volume, and such. It'll play music fine upon turn-on for 20 minutes and then crackle one day, the next day it'll crackle after 20 seconds.
Consequently, I'm going to have to sit right in front of the speakers and wait before I can see what each test results in. :)
I may try leaving it on as well. Thanks for the tip.

Does it happen on all front end equipment?
Have you tried a different source?
Intermittent problems are often the most difficult to diagnose and fix. Sometimes you just wish the equipment would fail outright!
A couple tips for finding intermittent problems. You can try to use hot and cold to see if you can cause the problem to occur more consistently, or to squelch it. A small heat gun directing heat to the suspect area, or a can of freeze spray used in a similar manner. You can spray individual components or area of a circuit board. Look for cold solder joints, reheat suspect solder joints. Carefully flex a section of circuit board by applying pressure to see if you can cause the problem to occur. Apply slight pressure to individual components. Of course be very careful with live circuits.
Intermittents are a PITA.
