As a new user for almost 4 month, I have to say, that I am not overly impressed with the sound of the KPA for live situations. For my home recording Studio the unit is great.
I still can not get used to the grainy, artificial distortion sounds of the unit through the dxr10. That's why I still prefer to play my Marshall live.
However, it seems that the KPA can also sound great live as it is shown on various YouTube videos, which were captured with a mobile phone and not pimmped up in the studio to make the KPA sound huge.
For myself I decided not to return the unit and to spend some more time with it and see if I can make it work. Even, if I decide to sell it after a year, it will not be a problem as it pretty much holds its value at least here in Germany.
Recently, I talked to our sound guy, who is a professional and is also mixing other bands, he told me that one of his clients uses a KPA live, but it took the guy almost a year to make it sound like a good Marshall amp.
Now, as a professional, I would assume, that one can spend more time with the unit and can make it sound good quicker.
But I am not really, there. And if not, I will use it as practise and studio amp and play tube amps on Stage.
