Yes, and they were built by a guy who was a professional trouble shooter for three of the top electronic manufacturers in the USA and Canada, and has seen 10s' of thousands of failures and fixed them all
He was also a quality engineer and process engineer for several years as well...
So his stuff is built pretty good.
T...Now I am narrow down to DAC straight and Ibasso D10 which also can benifit my protable rig. But I don't know which is better on the DAC part?
I know ibasso D10 use a WM8740 chip.
I ordered a Darkvoice 336se the other day, directly from Darkvoice (well the whole process of ordering took actually 8 days!) I had problem already during the ordering process, so I am crossing my fingers that the amp will not fail. Because it is probably gonna be a huge hassle if I need to send in back for repair.
My DAC supreme on the other hand, I almost wish it will fail, because it is such a joy to experience Dave's costumer service
But seriously, you should always considered the possibility for a failure, and I know that I would not be worried about Dave's support.
