Surprised that no one has asked you this first, but are you looking to build a two-channel or multichannel system with that budget? That will go a long way in deciding what to buy.

For now, I would suggest that you try listening to as many speakers as you can. The ones you've listened to so far cover a relatively limited range. For what you listen to, you might want to give the Canadian speakers a try (i.e. Energy, Paradigm, PSB, Mirage, Athena). They typically extend the highs a little more than British brands, and dial in more punch in the midbass and project a wider soundstage. Depending on the electronic music that you listen to, those characteristics will work well with the imaging cues that get mixed into a lot of those tunes.

Klipsch and Definitive Technology will provide a more aggressive sound. I also like the Dynaudios overall, but if you go with those speakers, you will need more than a multichannel receiver to power them due to their low efficiency and low impedance. The Magnepans are nice with acoustic instruments, but I did not like them as much with amplified instruments and heavy percussive sounds. Another company to consider is Vandersteen. Those speakers image extraordinarily well and use the best matched center speaker I've heard, but do other things that I found bizarre. However, Vandersteen has a lot of strong supporters, and some high end reviewers use Vandys in their reference system.

Once you've found a set of speakers that you like, remember to try them out at home to see how well they match with your room. The choice in amp will depend on the speakers you pick (going with a five low impedance speakers is generally not recommended on multichannel receivers unless you add an external amplifier), and whether you intend to stick with two channels or go multichannel. (The designs are very different in that two-channel amps are all-analog, while multichannel designs incorporate digital processors and conversions in the signal path)

Take your time, do your listenings, and remember that in the end, it's your opinion that matters the most.
