Are you saying he would be perfectly happy not having an experience that will give him an itch?
I was perfectly happy with my Bose 601s for 12 years. Then I made the mistake of listening to a pair of Polk bookshelves that were set up just right. That guy knew what he was doing. I got the itch that led me to my current system.
So if chaos was to say "Bugger off, Mojo. I don't want to get an itch.", that I can understand!
I looked at a post of his previous room before giving advice. He was in a 10'x19' room based on posts from 8 years ago.
BTW, I am not saying he's going to like the KEF bookshelves over the M80s in that room. It all depends what is most important for him. However, he will certainly have a different perspective regarding his two options.
