Pkelly1504,
The speakers you're listing have so different characteristics, that I'm not sure what you really aim for upgrade or listening needs in general.
I would subtract B&W mentioned since they will not sound right with your amp.
Due to your extreamly high celiings, it's encouraged that you will build an acoustic trap another words building a stage 'tent'.
Please keep in mind that dealers often sell used speakers so you can pick them up to avoid shipping problems and charges. Not that I encourage or have any kind of interest recommending any dealers or stores, but definitely if possible, buy them locally. In Phili/Jersey I think there's a tons of possibilities from dealers and private sellers.
