@laginz "I agree that the simple “volume” knob is part of the equation in creating a front perspective, but not the only part."
Would the other part not be to do with the recording itself? For example, placement of microphones (assuming a natural venue since you mention front row and mid-hall)?
If you really want to make a change, try DSP where you can switch between venue types. A lot more options than swapping a power cord!
