I agree. Kemper is great but can be improved especially with the mids.
This is more the request that is need if there is room to improve. But i think to subjective. I dont know if this is actual limitation or only in the ear of the user. But if you want Kemper team to look at this. Give them objective data and not only what you think you hear.
For example a problem statement such as this.
"The profile created by sound engineer under optimal condition. The profile analyze at 95% accurate to the original amp signal chain recording.
Attach example of spectrum analysis of the original amp signal chain and the Kemper profile signal output. The chart show a missing high mid frequency when the profile is compare to the original amp."
Then if the example is validate by Kemper team they will decide if 95% is ok. Or if they want to improve this.
Again this is only example. I have no idea if the mid can be improve. The profile sound perfect to me.
