Once Again... Just So You Know...Just so you know... all of their new products are "way over-priced" compared to their prior products and the great amps available from US/Canadian mfrs (e.g. Woo Audio, Singlepower, MAD, Headamp, RSA, etc., etc.).
Darkvoice has attempted to increase their margins by bringing out "new and imrproved" versions of their products, which likely are only very slightly better than their old versions - "not that there's anything wrong with that," if the market will bear it.
They've also introduced these products after a 20%+ increase in the value of the Yuan against the Dollar (the unfortunate disadvantage of the reduced value of the Dollar - to US consumers). The result are amps, which are priced in the vicininty of a lot of great amps you can buy right here in the US, and avoid the huge cost of Worldwide shipping, and the relative risks of a warranty that can only be honored after a huge return shipping cost. This is also true by the way of the EU products - they're priced out of competition with great US products (the fortunate benefit of the reduced value of the Dollar - to US mfrs and their employees, anyway).
Unfortunately, some domestic mfrs (one in particular), have taken advantage of the increased prices of foreign produced products, to "inflate their own prices" by 20%+. But, you're likely still better served to buy domestic products, unless you're buying the original Darkvoice amps, which are still reasonably priced - though you still have the warranty risk.
Darkvoice makes great amps... but... they're pricing them out of competition.
