Usher DMD tweeter upgrade: worth it?

The pair on AG currently are boasting cardas internal wiring and i've read some xover upgrades offer better performance. I'm not sure what needs improving or what long term listening will show but I would like to see more exposure for the brand. I like that Ushers don't need uber expensive electronics to play dynamically. it really makes them feel like that much more of a bargain.

As a current and long time owner of Usher Mini-Dancer 2 DMD speakers I wanted to know if anyone has replaced the supplied footers with Isoacoustics Gaia footers and their carpet based spikes? Was it an improvement or not?

Judging by the build quality and design of the footers on my Mini Dancer DMD 1s, I wouldn’t have thought they could be bettered...?

The original (BE) tweeter was titanium and measured fairly flat and seemed a pretty competent tweeter, it's only issue was dispersion above 5K narrows because it's a 1.25-inch tweeter. The new (DMD) tweeter is ceramic which is theoretically a better material than titanium for tweeters, but I haven't seen any measurements of the newer tweeter.
