"at that kind of money I'm looking for new. and to answer zd542s question the end of game speakers means never feeling the need to buy another pair of speakers again."
What you're attempting to do here is not plausible. First, there's so many speakers to choose from, you have to be the one to make the selection. We all have different tastes. I could recommend a pair of 10k speakers, and you may hate them.
There's also the question of what electronics you will be using. The results you get are going to be directly related to every component in the system, not just the speakers. And the more expensive and revealing the speakers are, the more important this becomes. You can't listen to any single stereo component. It has to be as part of a system.
If your goal is an 80/20 split between music and movies, I would recommend that you do a 2 channel system only. Maybe do a separate, less expensive, theatre system in a different room. If not, you are going to pay dearly for the 20% that is the theatre portion.
Most important, is you need to verify that what you want is achievable. If you can't go out and demo some gear that you know you will be able to live with, you can't expect to achieve your goal in your listening room. I know its not the easiest way to go about this, but if you really want to get the last pair of speakers that you will ever buy, you have to do it right, or it won't happen.
