I am a relative novice to the AV world, but my wife and I are looking to install a nice home theater system in a room which is 45'x25' with 17' cathedral ceilings. This won't be a dedicated home theater room, but a living room where we'll watch movies/listen to music. We're trying to balance getting as nice of a system as we can without overspending unnecessarily as the space that will never be acoustically or visually "perfect" We know we'd like a projection screen (120"x67.5") with a 7.1 setup, and we've agreed to spend up to $60,000 on the equipment. Do any of you have suggestions in terms of equipment that you'd recommend taking these parameters into account and the fact that the space will never be "reference" quality? We have an AV guy helping us out, but as he always tends to push the envelope pricewise, I'd love to get second opinions on products that I can investigate. Thanks.
