Christian, stupid as it might seem, a fairly major reason why I didn't site my gear down here in the main Chapel signature space of 35x30x20, which could have been amazing for music reproduction, was the fact I'd need to plaster the walls and other surfaces w acoustic treatments, and this would have been totally incongruous and downright ugly w such a beautiful space adorned w original panelling, wainscotting, ballustrading etc.
And w the copious slap echo in this space, those panels would have been plentiful and totally visually jarring.
For this amongst other reasons I decided to spend the $80k needed to create the bespoke loft space. Here I can treat the walls to my ears' content.
I do hope you get lucky and not have to do much to tame your beautiful new room. For me, I wouldn't have been fortunate.
