I personally think that dual amping is a bit old now. A good option to have though. I feel that a choice to be able to mic up an amp like you would do in the studio, would be a lot more realistic. And I mean internally with Kemper possessing 2 or 3 mic inputs that can do a profile each and then you can mix between the different mics or cabs if needed. And each profile should be able to recall all three of these profiles within one profile, so you can adjust on the go if one mic number is too dominant.
USB instead of s/pdif is of course a must. Backward compatibility would be very cool. There might be a slight change in sound. Who knows. The display and UI could use an upgrade. I agree. I only use the RM though.
that would be an awesome upgrade!
