I did not need test equipment to tell me that something was wrong with the Outlaw amps. I compared them to comparable amps from another manufacturer that did not have the same problem.

Most people will not have "clean" power coming from the street, there will always be artifacts of one sort or another. Therefore, it's important in my mind, at least, to get equipment that does well under normal conditions and not just on a test bench in a lab under ideal conditions.

The B&K performed better under normal conditions (normal in this case defined as my home, which is the only space that I personally care about) than the Outlaw.

THAT is direct, repeatable observation. You can dance around it all you want, but that's what happened. Why it happened, is quite frankly, immaterial. The fact that it did happen, was to my mind unacceptable which is why I have a B&K amp in my rack and not the Outlaw.

You may have different experiences with the Outlaw than that, which is fine, but I can only report on MY experiences so that others know what problems they might expect to have.
