I love the Kemper for the flexibility and convenience, but after 2 years I am still unable to get a sound that I can live with through a speaker cabinet. Relative to a real tube amp, it lacks punch, directness, and low end fullness relative to a tube amp driving the same cabinet. I have concluded that a big part of the problem is muddiness in the lower frequencies (harmonic distortion?). I have had some success suppressing some frequencies in the bass and accentuating some mids to try to address the muddiness, but that means going in and tweaking every rig (which I gather most are not doing, and which takes me too far down the rabbit hole of constant tweaking rather than playing). Plus, the EQ block affects the FOH sound as well as the monitor sound (i.e. signal to the cabinet without the cab sim). I have tried multiple cabinets, and have tried driving with the Magnum 44, with clean audio amplifiers, and with the power stage of tube amps. I get the best results with the power stage of tube amps, but then I am left having to cart a tube amp for performances which largely negates the convenience factor of the Kemper. The only thing that I haven’t tried is a more expensive solid state power amp (e.g. Matrix). By the way, I have used countless rigs purchased from all of the usual suspects. I’m just about ready to give up on the Kemper and go back to my Mesa Triple Crown completely. So many people with better ears than mine seem to be completely happy with the Kemper - can anyone suggest something that I might be missing? Thanks,
Eric
