Any sound Differences between the Alpair 5.3 v1 and the new version 3 out now?

Good afternoon everyone. So I have the Alpair 5.3’s Version 1. I was wondering besides a few changes in the drivers mechanical suspension (mono) what makes this version 3 better then version 1? I was looking at getting the v3 but, Had no Idea if am wasting my money or is it that much better? I was planning on giving someone I know the older Alpair 5.3 v 1 if I got the new driver’s. Thanks Jeff
