I use a pair of Sonas Faber Concerto and REL with mine, it works fine for my needs.
If I upgraded speakers I would be looking for either a better SF of go to electrostatic speakers. However, going down that rabbit hole can get expensive. Mine is fed with Blue Node 2i , Apple TV digital inputs. For single artist recordings I love it, for group performances or classical recordings it’s more just a grin, you’ll need to spend some money to reproduce that.
Good luck.
