Still have my JBL L40 (circa 1977) and my ADS L520 (circa 1981) and use them frequently. Both still sound excellent especially when driven by good gear which of course I could not afford when I bought the speakers originally. In fact I used my Pioneer SX-680 receiver, which I still have, with the JBLs for a decade before moving to Adcom, just like many others did. Many consider Adcom as the gateway gear into hifi.
