If you can extend your budget to $2500, you can probably get a used pair of Dynaudio Contour 3.4's. Plinius and Dynaudio are considered to have strong synergy.
Speakers that mate well with Plinius 9200
I am looking for a set of speakers. I just purchased the 9200 and my room is apx 17 x 24. I like all kinds of music. Any suggestions? What are others using with the 9200?
