I currently own a Denon 3802 that I am quite happy with in my system. However, I just completed putting a 24 x 29 addition on my house that will serve as my dedicated HT room. Although not entirely complete, I do have have my components in there. In listening to movies and music it seems to me like the Denon amp is straining somewhat as I have to turn up the volume a good ways to fill the room with sound. The room also has a vaulted ceiling so it is a fairly large area. So with that said, I was considering using the Denon as my Pre/Pro and purchasing a dedicated 5 or 7 channel amp. I was wondering what you all think of this idea. Any problems with this setup? Unfortunately, after the construction, my bank account is a little thin to be going out and buying a whole system.
