Definitely not Cao's first CanJam. He was in Singapore in March, I spoke to him there and then and breached the idea of sending their stuff over to ASR there as well. You can ask if he recalls that though. ( I was the guy who has the HPA-3B he had on the desk.)
Maybe they are there under their own flag for the first time, as in Singapore, they were under Shenzhen Audio's booth.
Oh forgot to add, if you can get into a short enough queue, go audition the Raal SR1a headphones and share what you think of it.
If there is a unique headphone worth your time to check out, that's probably the one.
