I'm also not convinced that this particular screen shot is non-
linear distortion. It could be aliasing in the FFT software that's 
part of the decoder. 

On the other hand, the pdf below DOES show both harmonic distortion 
and IM distortion on the Line Output when the Line Out level is set 
too high (driving the transformer being driven beyond it's ratings).
