La Scala vs Klipschorn

I had a pair of Klipschorns for several years, many years ago. To tell the truth, other than I remember them positively, I don't remember much else. (Age takes it's toll!)

I'm considering buying a pair of Klipschorns or a pair of La Scala to replace my ESS/Heil speakers that have more-or-less turned to mush after twenty years.

Anyone care to tell me the differences between the two speakers?
