Thanks for posting the video of the KPA-500. I got to speak with the designer of the KPA-500 at Pacificon. He worked very hard at designing it to avoid the problems that occur in other solid state amps. I’ve seen pictures of the inside of the KPA-500 and the construction quality is as good as the THP amps. The KPA-500 isn’t inexpensive but you get what you pay for, especially in solid state amps. I plan on purchasing one of these amps in the future!
I found time to run a few 2 tone IMD tests with my K3 and KPA500 combination today, these were on 80m using a 50 Ohm Cantenna load with the spectrum measurements taken with a Microtelecom Perseus SDR. The SDR receiver was coupled via a loop of wire around the coax to the Cantenna. The two tones used in the test are from the internal 2 tone generator in the K3.

Love that KPA500 :-),,, Would like to see a Real Time Spectrum Scope without the shadow behind it

Thanks for the comments.
G4AON recently made the following measurements:
