Has speaker technology advanced during the past twenty years or so to a point that today's mid range speakers ($1000-2000+/pr) will readily outclass good vintage speakers? I still love my old but well maintained JBL 100Ts, especially now when driven by the 990/7700.

Of course, I realize the ultimate test is always in actual listening and comparing, but I was wondering if advancements in speaker technology have made as big a leap in improving the sound as have advancements in the other components.
