What constitutes a room?

I'd say yes. Depending on your tastes, you can have a wonderful setup with no close side walls, a somewhat distant front wall, and no rear wall to speak of which could lead to a line of sight all the way to the kitchen, giving you a rear hall perspective as you cook. 

I'd love to have that set up.

thanks nonoise, unfortunately the kitchen runs along a long wall, the l/r & d/r run along the other long wall so the speakers have to be along the 33' wall facing the other 33' wall which is 25' away. I suppose I could put the speakers on a 25' wall but the dining room table & chairs would be in between them and the listening area (couch). Does this effect the sound much, the table & chairs in the way?

I'm afraid it would. There's still reason to hope so I'd get in touch with someone, like a high end dealer you may be familiar with.

Nothing compares to actually being there to hear just how the sound would work in your space. It sounds like you still have a lot of room to work with.

All the best,
Nonoise
