Sound differences between Copper and Aluminum Bus Bar Electrical Panels

I'm not sure what your whole point is. I don't see why I couldn't figure that out or fix it. I'm hardly afraid of 120 volts. I installed all kinds of smart switches on live wiring at my friend's place back in January. A $5 AM pocket radio would find that fault more effectively that a $1000 IR camera. That problem doesn't warrant the most technologically advanced diagnosis and analysis possible. "Hey! Arching breakers! Guess I'm going to Home Depot tomorrow!" Problem solved. 

Or.... You could just build an RF probe for way less than a thermal imaging camera costs. 

You ever wonder why utility companies don't use bus bars at substations? 

I'm 100% with Erik Squires. And to retort "This is a basic question" is silliness. Virtually nobody is asking questions like this. "My guitar tone has too much grit. Can you check the breaker panel for aluminum or copper bus bars?" said no musician in the history of recording.

Uh...... YEAH. In fact I'd say how that makes your stereo sound is the least of your worries.
