Hi All,
I'm william, Sound engineer of Digihill Studio in Nice, France
On Monday 9th of October at 7.30pm UTC+2 (Paris Time) we are going to have an in depth test of the kemper in LIVE on Facebook!
https://www.facebook.com/events/517726168574249/?ref=br_rs
This will allow us to show you all the possibilities of the Kemper, listen to a comparison with a "real" amp, and you will be able to ask us all the questions you want, so we can answer live and test if needed 
This will be in French, but as I speak english I'll be able to answer any of your questions.
So if want to know if kemper is for you, this live event might be the answer
See you all,
Best
