The Chord Electronics Hugo SILVER HUGO DAC Headphone Amplifier.

This is an awesome headphone DAC/amp, everything works great. Please read the manual, some of the controls are a bit tricky the first time. 

I had the batteries replace about 2 years ago, they are 18650's so replacements are not that hard to find. 

Comes with 2 USB cables and the charger, I don't have the box anymore but I will pack it very well when I ship it.

Great chance to get a good deal on a great headphone amp.

Let me know if you have any questions!
