Not sure if I agree with this argument. Non-linearities in the analogAdmiralQuality wrote: Again, these overshoots are by their very definition less than a sample long, so any added harmonics from the clips are going to be very high frequency. Higher than you can hear. And again, in the analog domain so they won't reflect back down into the audible range as alias frequencies.
domain will not only produce higher (integer multiples of the base
frequency) harmonics, but also lower ones if the signal contains
multiple frequencies (this is called intermodulation distortion,
see http://en.wikipedia.org/wiki/Intermodulation ). So even in the
analog domain, a non-linearity may produce distortion components
that have lower frequencies than the original input content.
In practice, however, I these distortion components are often
masked by the audio signal itself, and hence you won't hear them.
