Real "Bookshelf" speaker 4 bookshelf or wall-mount

looking to upgrade speakers used in my home office. The only place they can go is on a shelf, or mounted to the wall (which is solid). Currently using a pair of Mirage Omnistats which are designed to mount nicely on a wall. They sound pretty decent but are not stock -- WBT binding posts were added (the original one were not as "high-quality" as Mirage claimed and snapped off with some stiff spades), and after opening up the speakers to change the posts finding horrendous crossover parts quality, I swapped out the caps and resistors (to Solen fast caps and Mills resistors). They image well, give a credible soundstage, and fairly smooth up top. But they could be improved. What high-quality speakers out there are designed to be mounted on a wall, or placed on a shelf right up against the wall? Amplification is a Kora Galaxy (50 wpc), and the room isn't too large. A Sunfire subwoofer Jr. discretely handles to low end. Thanks for the help.
