I had a pair, which I thought had some good qualities, but might have needed some refreshing. But they are hard to get into, so I just passed them on. In some ways they are the progenitor of the Advent, via the KLH 6. The woodwork on them is very nice, but they are rare and collector enthusiasm seems limited. Everynow and then a pair will go for a surprisingly high price on ebay, but I think it is auction dynamics, not actual value at work. I may be wrong, but I don't think they command high prices normally.
