Normally I'm not a fan of whizzer cone single driver speakers, but that is often what is paired with SET's.
The thing is, for near field listening, you want a point source speaker. And these single driver speakers are that, so he's in luck in a way.
You can find lots of info from SET zealots on what speakers would be good candidates. Theres even a brand where you can swap to a better driver in the future.
The thing is I'd try to get the speakers further away from the wall. If he could set his desk up so the speakers were 2-3 feet off the wall I think he'd find better sound, even though the speakers would end up being closer to him. I just personally can't stand hearing the coloration from having speakers near a wall.
