Thom, you might want to take a step back and reflect upon your reasons for considering such a system. If I may be so superficial as to attach a price tag to such a system, how many systems have you heard which retail for over 100k USD? What differences did you hear between them, which did you prefer, and why? Take some trips to larger cities to hear what's available. Compared with the cost of the components you mention, the cost of airfare and hotel is very small. Enjoy some weekends out of town to do this. Some dealers (ahem :-) offer complimentary accommodations with no strings attached and travel reimbursement upon purchase, which makes it easier to do so. Just my two cents' worth, as I've been down that road you're on years ago and chose to look around for quite a while...it was worth it...
