Thanx to all for the warm welcome!
Last night was THE night. I made my first steps with the KPA in my living room with headphones and once in a while checked the sound on my tiny home surround system. It was just more comfortable to learn the basics and in addition I could have a glimpse at it - once in a while 
But now it was time to move the Kemper into my basement - my active JBL EONs were waiting - including this EON 18 inch sub, which can move some serious air.
WOW!
* All my sounds translated nicely - they kept their character and tone
* The EONs can sound very brutal and harsh and reveal any problem with the signal, almost like studio monitors. But the Kemper just sounded warm and creamy (I used mostly AC30 amps so far, I quickly tested a high-gain Peavey and this WAS brutal 
)
* Feedback characteristics at high levels seem just like with 4x12 inch cabinet. No such high freq stuff so many digi amps suffer from played through FRFR. I do play a semi hollow guitar, but made for higher gain sounds. Compared to my other digital amps the Kemper allowed some nice bit of higher levels before the feedback became hopeless!
* At really high levels the Kemper showed its extremly high dynamic range. Sustain for ever and its noise gates do their job almost magically. You can pull back volume on the guitar unbelievabley low and it still does sound nice with low noise
* This PURE CABINET parameter is great! If you turn it up you get the feal of a real stack for your rehearsal pleasure. Turn it down and the sound sits unobstrusive in the mix. With the settings inbetween you can seemlessly bring the guitar just to the right level of cutting through the mix. This parameter alone almost forces me to go the reamping road for mixdown (I guess I will always record three channels, stereo master + direct out, just in case)
* Integrating my Yamaha FC-7 pedal for wah-wah purpose was a breeze. No manual needed
I couldn't be happier.
One minor issue: as soon as I connected my laptop with USB to try the rig manager, the Kemper had some cheeping chirping noise, high freq like a cheapo synth's tone. Laptop and Kemper where on the same mains lead. Ground lift did not help. The noise gates helped a lot, but not perfectly. The good news is, that the Kemper does not need this connection for fine-tuning sounds. Its user own interface is more than enough.
God bless
