On first inspection, the relative percentage of harmonics seemed to be the biggest difference between amps. But after looking at it a bit more, I started to realize that it would be possible for nonlinear distortion to be caused by negative feedback loops in certain conditions. The one that is most obvious is output near clipping, but there are others. Then there are things like noise floor, the kinds of noise made, be they AC frequency (60/120Hz), rectification switching artifacts, or hiss from electron collisions and other noise sources. There are a lot of differences, to tell the truth.
