User defined digital inputs has been possible with all of Outlaw's receivers and processors: each input can have any coaxial or optical digital input assigned to it, even if another input is also already using it. I've used that feature for a long time now when using a DVD player as a CD player. The Model 990 takes it one step further: component video and DVI inputs are also assignable in exactly the same manner and coaxial and optical inputs. I am using the same DVI input for both the "DVD" source and the "7.1 Direct" source in this manner, and I have even at times configured the front video input to use a rear panel digital input and component or DVI input when tinkering around with something. The Model 990 also allows the user to edit the names of nearly all inputs (7.1 Direct, Phono, and Tuner being the three that cannot be renamed). The one limitation that crops up is that component and DVI video inputs can't be assigned to audio inputs (tape, CD, aux, or phono) - I get around this with CD's by having my remote macro switch to the DVD input first, since the 990 will leave the video switching input on the last video source used when going to an audio input. I agree that this sort of addressability is a great feature.

As for sales figures, Outlaw has historically not talked about actual numbers. I think that about a year or so ago someone reported having heard a sales figure of 2000 units for the 990, but that was some time ago and I don't know the background of that number.
