soundstage height should not be 5' above speaker. one of the most disappointing demo I heard was Wilson X-1 that made any singers 8' tall. if the singer appears to be 5' tall from the floor, your stage height should be fine. you can tilt the speakers up further to create a taller stage height as well.
adding tube amp to the chain will also create that holographic sound you are looking for, that's why I have lots of tubes in my system because most SS sounds flat to me.
