Just a short test... Commercial and non commercial DI and Merged profiles all through the same cab and mic vs a real amp through the same chain. Can you identify the real amp? All are Marshall style amps.

Dirty ShirleyIMHO there is a big difference in dynamics and low end quality.
In the room it's not so different because of the volume.
Have no idea, but I liked the JTM1 sample the best.
Not sure about the umphh as I haven't played the Kemper in such a setting, but there are thing I still miss that I only get from some tube amps. The Kemper is the best I've tried so far, and I enjoy it very much, but it still can't clone every aspect of every type of tube amp behaviour.
