Wilson Audio started in 1974. They recently had their 40th anniversary. Their current store in Metairie is nice, it used to be the Audio Resource store.
I know Jay Valentino, a friend of a friend. I heard that he and his partner closed the store in Baton Rouge. I think that Alterman Audio closed their store in Metairie a couple of years ago. Wilson Audio may be the only true specialty audio retailer left in Louisiana.
