I have extensive experience with Maggies, Klipsch, Focal, and many others form my lifetime in the industry. Really great speakers today cost more than your budget will buy, especially if your musical taste calls for Electronica and Rock, which are bass dependant and often compressed, which puts more stress on the speaker. Your electronics are adequate for now, IMO. The new Chora 826 is in your sweet spot, and you might be happy with Revel F36s. They both sell for around $2K retail and have plenty of low end.
My last thought is if you want something well suited to your music and better quality than what's generally available, do you have any builder skills? If so, Parts Express Solstice kits should be on your radar.
