So I'm jamming with my homemade profile of one of my fave tube amps plus the amp itself, using my voodoo amp switcher to play through both simultaneously last night.
Fun to play two amps at once, and in this case identical amps one just breaking up and one with some gain for a very full sound.
I was grinning ear to ear and thinking this was "one of the best sounds ive ever heard a guitar make- verging on grail tone"!
after a while i looked over at the tube amp and realized it was actually on standby so, making no sound. 
The tone i was hearing was all Kemper, and kemper alone.
if this isn't a big endorsement or the kemper's profiling and authentic tube tone, I don't know what is! I can assure you that never happened with any other modeling stuff I've owned.
I was quite blown away and I'm still grinning!
