I still love my Jades! I don't really take very good care of em and I know I should since I may not be able to replace them if any serious damage ever happened to the drivers.
One of these days, I do plan to beef up some of the iffy mechanical parts (hopefully before I have to).
I still prefer them to the O2's but that's personal taste. I've listened to the Omegas on lots of different amps (BH, KGSS,, BHSE, ES-1, ES-2, Woo GES, WES, RS Thunderbolt, Kevin's T-2 at CanJam, ExStata, 717, 007) so I really think I've given them a fair chance.
The SR Omega and the HE90 are both better than the Jades in different ways and similar in others. I'm just not sure if I'll ever have a pair of those.
To me, the area that the Jades as well as a lot of 'stats fall down a little is inner detail retrieval. Because of that, I don't enjoy large scale orchestral music as much as smaller ensembles.
I know that lots of folks don't share my particular tastes and that's more than OK with me. If everybody was the same, the record companies would only have to release "Greatest Hit's" collections and be done with it.
BTW, I think that the first run of Jades was at least ten and I'm sure there was at least a second run.
