Would you move to a bigger house if you could just to have a better listening room ?

naw, I like to listen in the same space all the rest of my life resides in. I don't want to sequester myself in a little acoustically padded cell. 

I might be odd in that I consider music to be a social thing, while listening room seem decidedly antisocial.

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.

We are not all that crazy after all, or so it seems. Bigger property size, yes, definitely, though I don't know what I would do with it. Probably nothing, just more private space.

no one said you are not crazy 😂 that's an entirely different question. We just commented on the move.

The very reason I bought this house was for the symmetrical living room..., but could always do better.
