I currently have the Signature and the a 20amp PM2000. I too am 75% music and 25% movies. I have heard the Dreadnought with my speakers which currently both the Aerial 10T's and Magnapan 3.5R. The Dreadnought is a fine 5 channel amp and few can dispute that, but so is the PM2000! Your biggest improvement would not be in changing your amp, but in your speakers. The Def. Tech are great HT speakers, but not in the same level as your amp and processor.
I have also played with a tube preamp and it does add another level of enjoyment to music.
Just my thoughts.
