Hey audiodidact don't despair man look at it this way zero in on exactly what your system is lacking and fix it. I realize this is easier said than done but a similar happened to me after my first Capitol Audiofest back in 2017. After hearing a bunch of systems I decided mine lacked midrange density. I decided I needed bigger/better speakers and a few years later I had them.
It doesn't need to be super expensive either you may find you prefer a box speaker to your Maggies and plenty at various price ranges. Also wondering in the short term if you've tried a sub with your Maggies? If not that may give you more of the body and richness you're looking for.
