Why do you need a digital to analog converter (DAC)? All digital music needs to be converted to analog before it can be heard through speakers or headphones. Most devices have DACs built-in and do a fairly good job with uncompressed audio, but sound quality can sometimes suffer with compressed songs or files. Music is being played from mobile phones, computers, and iPods more than ever before. Unfortunately, the built-in DACs can be sorely lacking. The resulting audio is often missing high and low frequencies and may lack depth. Whether you need a DAC for your home stereo or a portable DAC for on the go, OneCall has you covered with a large selection of products.
