What speaker after Thiel 7.2?

I'm not unhappy with my speakers, but I'm curious about what else is out there. My question is directed to those who owned (or very seriously considered) the 7.2s as to what they moved on to and their assessment of the change. Particularly, are you happy or regretful? What does your speaker do that the Thiels didn't do? What did the Thiels do that your current speaker doesn't do? Of course, those that went to a speaker costing considerably more should maintain some perspective.

Budget would be under 20k new (although would listen to speakers up to 30k), and listening room is 18x16 with an open-floor layout. This means that the speakers have no side-walls, are spaced 9 feet apart, and listening position is at 12 ft. Main priorities would be for a full-range speaker that images clearly, accurately, with a realistic soundstage, and good reliability/customer service.

Thanks,
Rob
