Focal 906 and Rega Brio 2017

Hello everybody, this is my very first post. I have Focal 906’s and the rega brio 2017 amp together with a rega p2 and a Schitt mani phono stage.
I’m not an expert but for me, they work well together. As I am considering to buy the 926’s or a subwoofer (maybe a rel) I would appreciate your views on how to go about it.

Thanks.
