Above your budget...
but you are so close to it:
Phase Technology dARTS system. 5.1 system is around $14,500 and a 7.2 system around $17,500. It comes available in-wall or in-room with a 16 channel 4000 watt digital amplifier and, among other things, a calibration system so that it sounds perfect regardless of any room issues. All you need is a pre-amp, DVD player, and a PC for first time set-up. Best system I have ever heard at any price point (I have heard a lot, including systems from JBL Synthesis and Meridian which run upwards of $80K+). Reviews from all the major pubs back me up!
If you are willing to spend $10K it's obvious you want a great system. The dARTS system would take a bigger investment but, in my professional opinion as an A/V systems integrator, you can't do any better for any amount of $. Those of you into home theater and want to learn about a benchmark systems out there google some reviews of it. Word on the street is that later this month, The Absolute Sound gives it a 10/10 review.
