Woo-hoo! I just got mine today via UPS - also no advance notification, but it's clear Craig and Mike are reading their emails, as they sent it to the address I asked. Trying 'em now with my JH13-pros. They replaced the v.1's which I never really had a chance to listen to, as Whiplash announced, right after I received them, that they were releasing the v.2s. So I can't really say how the v.2s are compared to the v.1s. I can say, with absolutely no break-in time, they seem "fuller" than the stock cable. At the same time, a little bit darker, for want of a better term, but I'm not worried about that, as I think they're going to open up very nicely - I'm just going by instinct here. They still sound great out of the box, but definitely different, In fact, they remind me just a little bit of how the JH16s sounded (when I tried them at a meet), while with the stock cable, the sound of my JH13s is brighter. But I trust Craig when he says it's gonna take a good 300 hours for the v.2s to open up - I think, fingers crossed, these are going to work out fine.
One very important thing - I think they're actually a little bit more comfortable than the stock cables, and maybe more than the v.1s, if I recall correctly from the little time I used them.
