I've owned the HDACC (first version, no 4k) for 2 years now and
all I can say is it`s the most versatile , good sounding DAC out
there without getting into crazy money. So many in/outs and the fact
that it has HDMI in/out is a huge plus. I run my OPPO bluray
player through it as well as USB, cable box, etc . Highest regards.
