Aune Audio - X1 Pro - 24/192bit/192kHz USB DAC Headphone Amplifier

Excellent build quality, inputs for USB and optical (among others), and high voltage. This unit drives my AKG K701s very easily, and any audio device can sound good even at really low volumes. I was expecting it to be larger, but everything about it is more than satisfactory.

It is good and I can feel some better than my computer onboard audio. I use it because I have some headphone need more power to play them.

It's working fine no problems at all

Hubby loves this, neighbors not so much. I don't even know what it is for but I know that he enjoys listening to his music now that he has this.

works great!
