What are you using now (if anything) for multi-channel sound in your home theater or listening room? If you already have an AV receiver and swap it out for spearates with either the 990 or 970 and an Outlaw amp, it really isn't that hard to do, Perhaps a bit of a pain to move everything, and remember that you'll need more space in your rack or shelves for a processor and amp, but otherwise it's pretty much unplug the old and plug in the new.
