Summary: I just wanted to share my experience with my Denon AVR-1909. I bought it September 2008 for $649.00. As of a few weeks ago, the Denon would shut itself down to a flashing ½ second red light around the power button. Pressing the power button would turn the flashing red light into a solid red light.
Summary: Yes, the Denon AVR-1909 is exactly the same in terms of specs as the AVR-789 with two minor exceptions: 1. the 1909 includes a small, second remote intended for Zone 2 operation, and 2. the 1909 has a plug on the back labeled "RF/RC 2WAY", next to the Sirius plug.
