Thinking about getting some bookshelf/standmount speakers

Right now I`m using Revel F52`s along with 4 subs.

I`m looking to change things up just for fun.

My room is 18'x22' with a sloping ceiling that goes from 8' to 13' and I have acoustic panels for sound treatment in place.

I don`t want the 'head in a vice' sweet spot first and foremost.

I`ll be keeping the 4 subs so deep bass is not a requirement but a big open sound with great midrange is.

I like detail and pinpoint imaging too.

The bookshelf speakers have to be as good or better than the F52`s (sans bass response) across the board.

Looking forward to your suggestions !
