You will go to all these lengths to prove the QC is better but the one thing you won't do.... edit the parameters of your Kemper profile.
You keep saying that. It simply isn't true. I've spent years trying to dial out what you yourself have acknowledged as a displeasing distortion character.
No amount of pre or post EQ gives me as pleasing a palm-mute response on the Kemper as the QC, or the original amp. This has been true for cabless signals as much as cabbed signals.
