I've got mine yesterday (SN: 179/6000), I'm in China.
This earphone definitely sounds amazing! I have no EX1000 so there is no direct comparison, but VSD5 is way better than my EX800ST (Well, maybe it's not important, EX800ST has a quite different acoustic characteristic with VSD5 anyway). My VSD5 had completed a burning-in for about 12 hour, and now seems like it is going into a stable condition. This one is not that easy to drive than the VSD3 series and it requires a little bit more power I guess, of course you may plug it into your iPhone or Walkman or whatever portable gears and it will always return you a decent sound, but when I plug it into the earphone amplification jacket of a Musiland Monitor 03 Dragon sound card, this little buddy just sounds like a K240S, which is quite amazing! I don't care if it will beat EX1000 or not, I just like it. I remembered about 4 years ago when I bought a GR07 and listened it for the first time, I couldn't believe it was really a 100% Chinese designed, Chinese made earphone, I was so impressed! And now that kind of feeling's coming back, God I love this one!
