I used to have NHT speakers in my HT system - 2.9's up front with the AC-1. I always found them revealing as opposed to necessarily bright. Unforgiving. Anyway, I drove them with the Krell KAV-500. Absolutely excellent performance for movies, pretty darn good for music. If you want a warmer sound, you might check out the Proceed Amp5 (or the Amp2 plus an Amp3). There are some great deals lately on the KAV-500 used, but both of these are more expensive options than some that have been suggested. -Kirk
