$8,000 budget--Need help

I am purchasing a new stereo system. I have a $8,000 budget to spend on speakers and equipment. I am working with a room filled with travertine that is 35 ft. wide by 55 ft.long with 18 foot ceilings. I am going to the CES Show in Las Vegas for my evaluation. One speaker line I am looking at is the Von Schweikert VR4 SR. Can anyone recommend speakers and equipment for my comparison? I listen to all types of music; soft/hard rock, pop, oldies, classical, jazz, etc. I enjoy listening to music that is very defined and realalistic. I do not mind used equipment.

Thank you in advance!
