Just as a suggestion, you might want to think about paying a little more to go with a US distributer like GR-Research or Pacific Valve. I bought my Dac-60 from Pacific Valve, and they double boxed it, added power cable, and a warranty which I was very happy to have.
After about three weeks with the DAC, one of the channels just happened to fail. I sent it off to Pacific Valve and they replaced it, no questions asked. I've since voided my warranty by modifying my DAC, but I sure was thankful I had it then; mailing back and fourth to an Asian distributer would have been a nightmare.
