    item shipped fast and with the early bird deal was 20% cheaper than Amazon. The SK02 itself is exactly what I needed, enough power for most headphones and no discernable noise with sensitive IEMs. It also fits nicely next to my keyboard where the top mounted volume knob is within easy reach

    The hi———–man-r-out-and it sounded noise-free and low-tone dynamic. But compared to the upper aircraft species (Shanling H5), it sounded a little rough and a bit mugdy. It has optical input and output, so it can be used for many different purposes, which seems to be an advantage. It would be nice to get a lot of discount and buy less than 10 floors
