I have this
Hidizs DH80S for sale, in blue. This link has it bundled with a leather case, I don't have the case. I bought it stand-alone. Now they bundle it for a little more.
If you need a little more oomph/power for your headphones and want full detail retrieval from top to bottom, in a portable package, this is it. I think it uses a Sabre chip. Look up reviews, it's well regarded. It sounds better than most external portable DAC's I've heard but I realized I don't need it in my scenario.
I just bought a month ago and can't return it. I'm asking $110 shipped in CONUS.
