I think one of the reasons for the turnover is a more generic issue. Speaker placement for bipolar speakers (all brands mag or electrostatic) is critical. In the proper place in the right room they are killer. Unfortunately I think the problem pans out as follows.
You: Look at these wonderful new speakers!
Wife: They are too big but they are thin so I'll live with them up against the wall....
You: Well I've spent a week finding the perfect location for them. How do you like the sound?
Wife: THere is no way I will let you have them out in the middle of the living room like that.
You:Guess I'll look for a new wife or new speakers.
