I use the ha160d primarily as a headphone amplifier and a DAC for my laptop. My hifi system consists of Pro-ject Pre Box pre-and mono power amplifiers, CD players, speakers are Dynaudio (Contour 1.3).

Ha160d this is the best investment that I have done for a long time. This device adds value to my hifi system, improved my CD player and the sound from the notebook is huge!

I recommend the  HA160D, a SUPER headphones amplifier and DAC converters.
