Rich,
Have you thought about the upper end of Magnepan, Vandersteen, Vienna Acoustics, or Sonus Faber? I'm not sure how all of them would fare for HT, but I know they sound excellent for 2ch. Oh, and don't forget about the Linkwitz Orion. Although, they need 4 channels of amplification per speaker, so that may be in issue. But the bonus is, Linkwitz is based in California, so you might be able to arrange for a local Audition. Check them out:
