What Mojo is refering to is that on the Denon's you can adjust each speaker channel gain with out going into the setup screens via the remote. The remote has a button that is dedicated to speaker selection and then to gain control. I didn't know about it till he showed me\:\). So the Denons can already control the sub volume remotely, while watching a show.
