Tis easy enough to come up with a test regimen to examine what I look for..perhaps that is needed?
jj: ""
Now, signal dependent delay is also easily looked at as IM distortion, if you think about it, it's phase modulation, which creates distortion, eh? ""Perhaps it's IM. I am wondering if it can actually be called that, as the modulation products of amplitude based time shift is a rather unique entity, being related to the change in current slew rate of both signals..not an easy analytical nut to crack..
Measurement of this at low impedance levels at outputs is not going to be easy, the field storage for normal low z loads is a bitch to overcome, non inductive resistors are crap in that regard.
