Ain't nothin' wrong with movin' on .... I've seen guys sell their Kemper only to come back a year later saying they were crazy to get rid of it. But some guys just disappear forever presumably back to amp land. There's no right or wrong. Whatever works for you.
As for me I've always kept my amps which I play through almost daily. Keeps me grounded in some kind of sonic reality. The Kemper is something else. I don't see myself ever selling it.
Just keep playing. You have your own musical journey ahead of you. Wherever it takes you is the right place to be.
Good Luck!
