I would also recommend the Eidolons - ultimately, I found them to have a more sophisticated presentation than the Indras, a touch more resolution, and more transparency through the midband (although to agree with Rushton, the Indras have more authority in the midbass.) Unfortunately, the "newer" Eidolons (Vision and Diamond) are probably a bit out of your price range (tough to find Visions for <$14000 used).
In terms of amplifiers, I think the Eidolons perform their best with high powered tube amps. CAT amplifiers are a particular synergistic match, although VTLs also work nicely (I believe Avalon has been using these at the high end shows). I have also matched them successfully with BAT monoblocks, and even an Air Tight ATM-2.
