How do you measure "image" height? Your imagination calculator? Height for performing musicians is relative to your distance from the performers, and the height of their sound...well...are musical notes height quantifiable? My system images well enough that I rarely think about it.
An aside...One of my criticisms of studio mixers is the mixing of drums. Too often they pan a cymbal (or any drum really) so it seems to be played by somebody thirty feet away or the mix showcases a twenty foot wide drum kit...lame.
