Considering Towers in the $3000 range

Is your amp a SLI-100 integrated? How "large" is your room? Avoid "home theater" and "party" designed type of speakers. The best 2 examples could be the Monitor Audio Silver 500 7G or the Sonus Faber Lumina V. Have not heard the 500 7G but was impressed with the Lumina at <$3000. I’m considering a Nova 2 as an upgrade from my Focus Audio FS8. If your music tastes are >33% current pop/metal/hip-hop/techno the Monitor Audio should have the edge. Jazz/classical/well recorded music would favor the Sonus Faber due to class leading tonality/timbre.

A big room?  Efficient needed.

Horn speakers can be high priced based on your budget.  I bought Crites.  They require finishing(possible show stopper for some.  Currently they are $2200 delivered.  The speakers set up properly are very good sounding and 100 dB efficient.

I have seen these veneered and they are beautiful.  Mine are clear coated Baltic Birch.  My last speakers, unless I  move to smaller place.

MA for sure. If you HAVE to have a tower.

+1 I go with Double Impact or Moab.

I agree with the Moab's, however, if size is an issue, then definitely consider the Double Impacts or the Pendragons; right in your price range. Incredible value and incredible products. I own a pair of Moab's with the Be tweeters. Could not be happier, and I've owned some impressive models of other speakers over the years.
