Everyone is going to recommend the big speakers they have, for example I would suggest Maggie’s. That said, it is your ears and your room and your budget.
There is no substitute for listening to a well set up system, be it another audiophile or a dealer who knows how to stage a room. Give planar a a listen, they are not for everyone, but many of us became hooked at the first listen in a well set up room.
Good luck in your journey!
