DAC Chip
You may not even realise it, but most of us use a digital-to-analogue converter (commonly known as a DAC) daily. Built into your computers, tablets and smartphones, a DAC is fundamental to unlocking the convenience of digital music. Any device that acts as a digital sound source will need a DAC to convert digital audio to analog. A DAC converts the digital information stored in “0s and 1s” into an analog signal that's passed to speakers or headphones and ultimately our ear. In short, DACs play a large part in making digital music hearable. 

While this technical process is undoubtedly impressive, the DAC embedded into your smartphones or laptops is nowhere good enough to listen to your favourite music recordings in high quality. So, if you want to listen to music in high quality, an external DAC is essential to allow headphones or speakers to perform at their potential. An external DAC, first and foremost, will improve audio quality dramatically.

The Audio out that used was from a imac pro via USB, the sound was crystal clear, used audio hijack to run few VST's so i could fine tune the audio for my taste. used utopia headphones on it and i could definitely understand the difference! Loved it.

We are incredibly grateful that you took the time out to leave us this note. We look forward to serving you again.
