High efficiency monitors for SET amp in small room - budget 2.5k

Soliciting recommendations for high efficiency monitors that would work well paired with a relatively low-powered (22wpc) SET amp (Line Magnetic LM-218ia) in a small listening room. Budget is modest, around $2,500 and potentially stretching to $3,000 - thinking I'll be looking at pre-owned. Listen mostly to chamber music and jazz, not really worried about reproducing large scale orchestral music or rock.

Thanks for your thoughts!
