If you’re a music lover and you want the best listening experience, one of the key ingredients in the quality of your sound is the digital-to-analog converter or DAC.
A DAC takes the digital information on your computer and translates it into analog sound you can hear through your headphones and speakers.
Not all DACs are created equal. Your computer has a DAC built-in, however without a high quality DAC like Groove, you will miss out on much of the subtlety, detail and dimension of music you listen to - regardless of what headphones or speakers you use.
