How much do you have to spend, what kind of music do you like, and what characteristics are you seeking in your speakers?
If you don't want to spend a lot of money then one choice that jumps off the page at me in light of what you have now would be the nOrh 9, which I think is a very fine reproducer at a very reasonable price. It is better than the Hales and a LOT better than the PSB. Depending on your taste, you may want to consider a well-disciplined sub to go with them.
Another option if you can spend more would be the Hales Trans 5, another wonderful speaker. At that price point, though, there are lots to choose from.
Good luck!
