There is little point speculating on the reasoning, although I would agree that Kemper have tended not to follow but carve their own direction. Conversely they are a company in business and also have a history of listening to their customer...so I suspect its bit of both. However, if it was to keep up, they would have added a colour touchscreen so...
Also, comparing to NAM is irrelevant - I can't use it live easily. The functionality and workflow IS a big part of a unit, not just sound. It why the KPA is still such a great solution when you also add the power amp built into the rack/toaster and Kabinet.
With regards to profile accuracy, let me give you another view...for some people like me, I hate tweaking and fiddling. I don't want more sound options, I want just good sound...BUT...im also useless at finding good sound.
So for me its not about amp accuracy, its not even about adding endless tweaking possibilities, I just want the best sound...BUT....I can't necessarily get there on my own so I'd like the best created sounds for me on the best unit possible. Having 100,000 profile points is useless unless you translate it into an better end sound..
So, I will buy one, otherwise psychologically I will feel like I'm missing out. I bought a Kemper 11 years ago not really knowing much about it except it was a pro level piece of kit and I suspect I won't have all the answers before I buy a MK 2.
I do like the idea of keeping my original as it might become a classic!!
I suspect I'm not alone...
