Best Monitor Speaker?

I am putting together a new secondary system for my dining room, based around a new NAD C352 integrated amp (80 wpc) and a Rotel RCD-1072 CD player. I would appreciate some recommendations for a set of monitor speakers that would work with this system, with a ceiling price limit of about $800 (used). This system will be almost exclusively used for jazz, jazz big band, jazz standard and small ensemble classical music.

Thank you in for any feedback, it is greatly appreciated.
