My advice is to keep it to a minimum; use it when you need to address a specific problem. We live in a reflective world so that is what sounds natural to us. Listening to music in an anechoic chamber, void of all reflection, is not a realistic or pleasant experience. We need the anechoic chamber to be sure our family of curves is delivering the original recording just as it is into your room. Turning your room into a quasi anechoic chamber or trying to artificially create flat in-room curves measured in one or a few seating positions is playing with fire.
