I've not checked out these particular suppliers from China, but I'd be rather concerned about warranty issues. I'm assuming, if there is a warranty (meaning it's not just offered, but is actually honored) it is going to be different (shorter and/or less inclusive) than that from the official US distributor/dealer.
It's gotten to the point for me that I just won't order bigger-ticket stuff from resellers in China directly as the last time I had an issue with one the offered resolution wasn't "Return it for a Refund/Replacement", but instead was "Keep it and we'll give you a discount!" - which was wholly useless as the item in question was dead-on-arrival! Wasn't audio related, but still was a pain to resolve.
Also, bear in mind that if the vendor doesn't cover the customs duties you may well get stuck with that - depending on how the particular customs agent is feeling that day. Typically that'll show up as a bill from the shipper, though I don't know what the charge would be.

I've also had a couple of people ping me both here, and in the real world, about their supposed "Level 3" units. I say "supposed" as they didn't come from "Kitsune HiFi" (which is also "Holo Audio USA"). As far as I know the only way to get the "Level 3" unit is via Kitsune HiFi, so I'm not sure what these other people have actually received. That could be anything from being sold one thing and sent another down to them just saying they have a "Level 3" without really knowing what that is.
Anyway, despite my personal impatience for getting my hands on the thing, I stopped short of risking an order outside official channels.
