Please give me your 2 cents...budget 30-50k

I am building my second home theater/music room. My previous attempt was extreemly expensive (in excess of 100k) and I sold my house and the system prior to using. I am attempting to cover both music and theater without going crazy. I am concerned about buying used gear, maybe it's not a valid concern but it's mine.

I have other systems in the house family, master bedroom, home office. This system will be in my guest house/ personal space, billards, bar, music, sports, etc.

I am considering Aerial speakers (7b,8b, or 9) Revel, B&W, Sonus Faber, Vienna...

Amps and pre/pro???? Proceed, Krell, Parasound Halo sereis, ATI, others?

Front projector HD 2 Runco, Sharp 12000, Marantz, Dwinn??

I have a varity of dealers here in Scottsdale Az. I look forward to your input.
