I'll tell you where I lived as a kid, the biggest brand in the Bay Area was Infinity and Klipsch. Martin Logan was for the rich and famous and B&W was around lets say. VMPS was very popular, almost cult like and JBL was everywhere. A lot of music makers used JBL in their homes and there were a LOT of music makers in the Bay Area.. Every rancher I knew had JBL, Mac or Marantz valve gear..
