Get a good 2 channel preamp, it won't color the music like your reciever will (I had that same reciever, and now have the 3808ci), and you will be shocked at the sound.
I love the S2's, I think it's crazy to look at almost any other monitor, especially more expensive ones, once you had heard them. Just a great speaker.
I still like my original advice, if you need a crossover for your sub, get a Behringer, they are a great buy. Also, room correction software, and crossovers are great for movies, not music, in my experience. I finally bought a Rel sub so I could use it for both. It too forever to get the crossover set correctly for 2 channel, but it was well worth it.
Good luck.
