KLH Model 20 or Advent 2002

Which are better?

I'm looking at both of these speakers. Both of them need a little work. I haven't had the chance to listen to either yet, just wanted to get a feel for which might be consider the stronger choice.

I wanted to add I don't know much about either of these speaker's history, just that they are pretty well regarded. I'll be powering them with a recently found NAD 3020. :-D
The KLH 20 was a (highly regarded) compact stereo from about 1970 with a pair of KLH Seventeen speakers. There are pictures and videos of it on youtube.
