I think you can safely remove the atoms and titans from the list. They're certainly great speakers, but they're meant for lower budget systems. Stick with your other options. On your list, I've heard the minimonitors, but don't remember them well. I think from what I remember, they were very nice speakers, but sounded a but too detailed/harsh to the point of distraction. Both the Energy C-3s and the NHTs are superb choices (my 2 favs in this price range).
Where would you buy the Paradigms, NHTs, or Energys? I know Paradigm doesn't sell online.
Now the plug: Keep in mind, I have some NHT SB2s in very good shape I'd be willing to part with if you went that route!
