You guys can say whatever you want to say but even based on clips alone, kemper recorded tones in regards to realism and musicality are untouchable by anything in the modeling world, the above video you posted was done in the spirit of fun but in regard to real world comparison, you gotta be a fool to even consider it as an actual representation of what each of the units are capable of. Kemper is in a league of it's own and here's the proof.
Check these kemper clips and search the whole wide world web for anything from AXE II to Helix to Bias and if you find anything that you think is in the same ball park, then post a link to the video or clip. Very easy task, find the best Marshall tone from any modeler, or anything Bognar from any modeler that can touch these tones (Raw Amp tones), and then you can come with a straight face and say that they're even comparable. Let's do that in the spirit of fun just like the opening post video. I will not post any Marshall from Bias , Helix or AXE so I don't get accused of being Biased and picking bad ones, but everything even the best that I could find sounds like absolute crap compared to the Kemper profiles,. so I let you do the picking ad good luck finding anything that's within a mile .
