MadH,
I have no quarrels with you or anyone else here. In my own personal profiling (which I have done over 150 times at this point), I have noticed that the KPA usually imparts a bit of it's own DNA when I compare the final results - this is not a problem for me because I almost always like the final result once I've tweaked it to my personal preferences. (I am referring to the basic nature of the distortion, as opposed to EQ or Cab matching issues). But I would disagree with anyone who says that the KPA is a totally transparent, tonally neutral sound generation device - and WHO CARES, as long as the tones are usable and pleasant to the ear - I was just making what I felt was an obvious comment about the current state of all the modelers I have tried to date...
We can all agree that the KPA does not create a 100% perfect replica but that does not mean that the KPA is introducing a signature tone on the profiles. When you say that the KPA has its own unique signature tone, what you are basically saying is that you are able to recognize the Kemper VS something else in a blind test.
