there is nothing to really hate about this DAC, it has given me no problems and it has a pretty powerful headphone amp in it

It has a decent headphone amp that sounds ok, and produces clarity and definition as a dac

The headphones I own are powered well, and I've routed the output effectively to an Audiosource speaker amplifier

I got this to decode optical audio from my TV as well as to power my Sennheiser HD600 and Etymotic 4 series headphones
