If you are looking into home automation, I'd check some custom installers. They will have the 6 zone switch boxes and the like. When I remember the company, I will send along the info for a 12 channel amp.... Knoll systems is it, check out their site at knollsystems.com They are a company for installers. The products they sell are HQ. The projectors are simply rebadged Infocus. My neighbor was able to convince the builder to let him do all the electric work and he set up his house to the max. He put in security cameras, 12 CAT-5 lines, and speakers throughout the house. Problem is he has to listen to the same thing throughout. The Anthems will give you the ability to listen to different sources, again one may be a digital signal and the other must be over analog. So if you want to rock out in your room while the wife or someone else listens while doing dishes, cleaning, etc you can do such. My next house will be setup like this, can't stand listening to Hit List while working outside.
While the AVM30 and Statement D1 look similar they are quite different. The D1 has dual Moto processors, 192kHz upsample on all sources (maybe just CD's??), and a $5k price tag to name a few.
