In your original question of what order to buy equipment I would just like to add my thoughts on that. I would like to think that I have a decent speaker system and I would just like to say that in my opinion the speaker that made the most difference and improvement in my home theater system was the center channel.

This is the fourth and final center I will own. It is hard to explain but the sound I get out of this speaker makes the voices sound exactly like I was in a theater. The other three I have had over the years gave me the voices but not the BIG sound you get in an actual movie theater.

Different people will give you different opinions but for me the most important speaker when listening to movies is the center channel. Others will say the surrounds or the sub but for me a quality center made the most difference. I would put a quality center that matches the two front on the list before getting the surrounds or sub. As already mentioned getting a match across the front is very important. I would get them at the same time to insure the same sound field accross the front. This is just my opinion and you can throw in in with the rest that were given.

I would like to add that when listening to music I only use my front two towers only, no surrounds, center or sub. The speakers I use handle the bass just fine by themselves.

Just remember that each person has their own preferences when listening to music or movies. The thing you need to do is find out is what you like and buy the best you can afford that fits into your budget. To me getting the best you can for your budget is the goal. No matter how great your system ends up there will always be a better one our there so just get the best YOU can afford, Jeff
