Still proud owner of a pair of BL6000's, I was wondering... the BL6000 and BL8000 have been around since 1992. They're in their 18th year now (wow, they're finally adults!). The only B&O speakers I can find that have been around longer, are the CX50/CX100 line, which have 19 years on their tracks. So... if the BL6000/BL8000 keep up another year, they'll have matched them and a year later: beaten!
Will those be the longest running speakers ever? For some reason I can't imagine any other company building speakers that stand the test of time SO well. Can you?
