I had Nautilus 805's and found them on the bright side as well, I think many feel the same and it's mainly due to the metal tweeter. Room acoustics and electronics also play a big part.
They are quite power hungry speakers, especially if you're trying to fill a large room. The Nautilus precedes the Signature, and then the Diamond. There are crossover upgrades in the newer versions that smooth out the highs a bit. However, like I said, I blame the metal tweeter. Have you looked into other speakers?
