Good analogy. The cars that excited us early on and the audio gear we all lusted for but could not afford. A walk down memory lane for sure.
I recall a few model numbers all the years later including the KLH 7,8, 23, and the smaller 32. Your JBLs (100s?), supposedly the "west coast" sound and the Advents, the east coast equivalent were very desireable. My first speaker system was a pair of Nova 8s from RS, pretty but unremarkable sound, followed by the McIntosh ML-1C I traveled to Chapel Hill to hear. I had those vintage (71) speakers reconed and recoiled back in 2006 and refinished the cabinets at Bluesboys shop in 2006. I drive them with a vintage 62 HK tubed reciever as a second system.
A bit of trivia most of you know..........JBL were the initials for James B. Lansing (Altec Lansing fame), who along with Henry Kloss, and Julian Hirsch founded the KLH company. Hirsch was in business with Houck who started the Hirsch-Houck Labs.
I'll post a picture of the near mint ML-1Cs when I find the "post a picture link".
