I would not move on the basis of a single reason like audio room. But moving is typically predicated on many reasons or a big compelling one (like a job). Then, while looking for a new house, you keep your eye out for one with a good place for an audio setup.
I was really fortunate to have chosen a house 25 years ago during a corporate job move. The house had two floors and one floor turned out to be my man-cave… library, fireplace, audio room (one of the best I have ever heard), office, bathroom, huge storage room, changing room. The first three areas open and connected to make the acoustics excellent. I was lucky.
