Best speakers for max. $3000?


  I would like to upgrade to some new speakers and I might have a maximum of $3000 to spend if all goes well.
I don't care if they are new or used but my real world experience is limited so I am asking the experts!   I know it is subjective.
  I have Mirage OM-7s now with a HSU sub.  My amp is a Bryston 100B SST.  
Also, I have a chance to buy a set of Thiel CS 2.4s. I plan to try them.   Thanks for any advice!

Many good suggestions here. Do suggest you consider room size, type of music that you listen to most of the time and distance from the wall be the speaker as suggested earlier by another audiophile. I think the Monitor Audio Gold 100 with Monitor Audio Stands are worthy of consideration.
Thanks so much for all of the information and taking the time to respond!  I tried the Thiels but they seemed a bit harsh with my amp at least.
I have a line on a set of SpatialM3 Turbo S speakers which seem to be loved by many. 
   Got some thinking to do.  I'm not complaining by the way!
If you are interested in the Revel F 206 or 208, then check out the HomeTheaterReview.com (11/18/13) article by Brent Butterworth. It will pop up on a Google or Bing search.

He picked the smaller F 206 because he already had a HSU subwoofer (VTF - 15H), because he felt that was a better match.
I have the Aria 926 in one system and Tannoy Revolution XT8s in the other. Both are great, but the Tannoy's are a little bit more lively and definitely have better bass. I paid $2388 for the Aria 926's in faux Walnut and got even a better deal on the Gloss White Tannoys. Both are great speakers for the price range.
