I would say Kharma but that might be out of your price range.
I would look into Sonus Faber's line of speakers. They are generally designed to project sound upwards and so they should fill your room with sound. 9' ceilings should be perfect for them. They're generally never picky about amps and I think most would find them attractive. And obviously, you won't find too many people who think their speakers are bright or fatiguing. You mind find the Cremona Auditors with or without a REL sub hidden in a corner aethetically pleasing.
