Starting on our own home theater

We had decided to upgrade our home theater and this time to spare no expense.  Well,  maybe,  we would spare a little expense but we did want it to be top of the line.   My wife started her side of the search looking for furniture for the room.  I started my side of the search look for audio visual equipment suppliers.  There are a lot of them out there but only a few actually had the equipment that we were interested in investigating for our room.   Ours is unique in that the room is small and has two doors so the placement of equipment will be limited.
