Don't put any credence in my opinion. I could make a very long list of amps I have owned over the last ten years and divide the list into two columns; amps I liked and amps I didn't like. What I like doesn't matter much as I have seen some of my least favorite amps recommended regularly. The Classe CAP151 comes to mind as well as your new Rega.
Hopefully you'll enjoy the Rega. If not, consider it part of the journey.
