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

Yes, but daunting.  I live in Silicon Valley and home prices are ridiculous so increasing space is expensive.  Pressure to stay local so that my triplets won't have to commute far after graduating college.  

I do have a 13x24x8 foot space, unfortunately it’s the family room full of furniture so converting it would be bad for my health and wellbeing - self preservation is the higher priority 😉
