What are your actual room dimensions? Is it 25x25x12?
Why do you prefer bookshelfs in that large of a room?
Id suggest that if you do want a bookshelf setup, that you go with a 7 speaker setup.
Id say get an Integra DHC-40.2 Pre-pro, $1200
add a Parasound A52 5 ch amp, and a A23 2 ch amp - $2250 and $950
Dynaudio Focus 140 bookshelf fronts - $2100
Focus 110 surrounds - $1600
Focus 220C center - $1200
Audience 42 Sat surround backs - $1100
Dual Hsu Research VTF-15H - $1758
That would put you near $12000 and if you get 10-15% off the speakers, amps and pre-pro you would be set, and you could probably ask for the dealer to throw in some speaker wire and interconnects, or use the 10-15% that you saved to get the cables or better cables.
