sub-$1000 bookshelf speaker/monitor recommendation

I'm putting together a living room system and looking for recommendations for speakers. I'm not sure if I'll get away with stand-mounted monitors, so I'm leaning towards front-ported or sealed-box designs, as these may end up on bookshelves. I'd like to keep the price under $1000 used. I would list the associated gear, but there isn't any yet! I prefer to build systems around the speakers, so I'm going to work backwards here. For an amp I'm thinking of a Pathos Classic One or maybe something from Peachtree. I'll be using vinyl and streaming from my server in the adjoining room. I listen to a really eclectic variety of music. I'm looking for some downright enjoyable speakers to listen to, as opposed to the last word in detail (not looking to master records in the living room, after all!). Thanks in advance for your help!
