Seems to use V380 MK2 a month, i connected my PC by USB cable, and my A&K Kann Alpha, or iPhone + Samsung phone. DAC part is just a fairy for normal use, if u looking for a great DAC, I think you need looking buy a separate unit
I also try using coaxial cable to connect my USB DAC ( Luxury and prescion W2), Sond is much open and little more details, high range more bright
But in this Great amp + DAC, is not much choice in the market. Solid Build, could increase or decresae the db power, a lot a power for your Headphone, or IEM too
I recommand for user who looking a 1 unit for daily use at night or office. That is your great choice and no regards
