The DXR is a great choice for sure. Ive tried the Friedman, ZLX, Headrush, DXR, and the XiTone. To me the XiTone sounded the best for mid to high gain crunch and lead tones but was very clear for nice cleans. Do you primarily play at home or out? If i only played at home i would buy a nice set of studio monitors. Honestly none of these speakers move air and get that thump that a nice 4x12 guitar cab gives you but they do sound good. it just takes time to get acclimated to the sound.
I play at home, but I need a speaker for if I were to play live as well. I'm just looking to get the most amp-like feel from my kemper. That being said, my best option for that seems to be the xitone. I just don't have the money for a $900 speaker, so the DXR seems to be my best option here.
