It all started when I moved my playback system from my 11' by 16' living room to my 12' by 17' family room: The latter has proven the better-sounding setting, and it's also sunnier and more accessibleand the floor is more level and stable. (The family room is a circa-2005 addition on a 1936 house.) And now that my speakers and my racks of gear have been removed from the living room, there's room for bookcases, books, and people who aren't me.
I am an artist-painter and an audiophile. When I listen to recorded music, I sit in the sweet spot and stare at the empty space between the speakers. And while I listen, I survey and critique the soundfield, as if it were an unfinished landscape painting in my studio.
As I observe the soundstage and the apparitions of musicians within, I notice the dimensions of the recording venue (and/or microphone placement), as well as the physical energy of the entire vibrating illusion.
