There are numerous dealers on taobao, all of which offer the base (level one) and the upgraded (rise ji) DACs. I'm not certain how the rise ji edition compares to the Kitsune Tuned editions for sale through Kitsune audio, but I think they're roughly equivalent to the earliest level 3 units.
Dealer authorization is a different process in China. Shenzhen audio is likely an authorized dealer there, but not in the U.S.
