Can anyone help me with diagnosing an electrical problem somewhere in my system?

A couple weeks ago I smelled that odor you associate with electrical fires. After the smell dissipated I turn the power amp on by itself and decided to start there and go upstream. After ten minutes I smelled that odor again so I dropped it off to be fixed and swapped in a spare power amp I have as a backup. Now I smell the same thing and this after playing it for hours without trouble. Does anyone have a routine for identifying the source of such a problem? Thanks in advance for any help you can give.

I would strongly suggest you listen to Atmospheres advice
 get a voltmeter on that channel Wires speaker etc ASAP and see if something is shorted.
 You need to find the cause not just replace and chase your tail.

I checked impedance for both speakers and they matched so I don't think they are a problem. I got the Art Audio back from Music Technology, it was a rectifier, and everything sounds good. Thanks, all, for the help.

I sent the DAC back to Mytek. They couldn't find a problem with it but for a fee they replaced it. No more problem.
