Classe CAM 400 or tube amp

I currently have the Classe CAM400 mono amps with Maggie 20.7. Can't really complain. But we are always looking for more euphonic pleasure whatever that means. I'm considering tube mono blocks such as Wolcott P220 or other. The Classe already sound fairly warm which I like. However, I have always been a fan of tubes. Already have tube preamp. Was wondering if tube mono blocks would really provide significantly more body/intimacy? Any experience particularly with these Classe monos greatly appreciated.
