Nanderson, I too am very interested in the signature 805. They changed everything as compared to the 805, they just look similar. Out of my price range though. I'm curious how many of you chose the M20 have noticed they are power hogs. The 805 don't seem to be, and when I heard the M20's, they were powered by a Levinson 383. Not terribly shy on power. I don't really want to have to change amplifiers if I go with the M20's. Thanks.
