They sent me a sample which unfortunately got lost. What you see here is the second sample. As you see, performance is just stunning. Use of dual DACs and excellent engineering has translated into a top of the line desktop class DAC but in a container that is the size of an America quarter! Functionality is excellent with nice tactile volume controls. And the thing manages to look attractive to boot! Other than finding out why it won't produce 4 volts, it is the most perfect headphone adapter I have tested!
