Theoretically, a person suspended atleast 20 ft from the ground level in an open field (pfa) with consistent air density and relative humidity, having a monitoring setup at his listening position(equilateral apex) with no type of reflecting surfaces nearby, can be considered ideal for monitoring only
Such a setup is absurd for practical purposes, but can serve as an excellent control for factoring out the effects of the monitoring setup while learning about the anomalies in your control room.
Do a room analyses procedure at the listening position with a measurement microphone, and 'subtract' its result from the one obtained in your control room. This way you'll have more data to work with in order to understand the effects introduced by rooms.
Every scientific study needs a control.
In simple words, the benefits of a well treated control room outweigh the ideal monitoring setup.
