What is a DAC?
A DAC stands for "Digital to Analog Converter". It takes digital data and changes it to an analog signal. This goes into a pre-amp and then into an amplifier which in turn plays headphones and/or speakers.
Music on Pandora, Spotify, Amazon Music, Apple Music, etc. are all in a digital format. (Actually music on a CD is in a digital format.)
One can also purchase the highest resolution music online from a source like HD Tracks, https://www.hdtracks.com/quality This too will arrive in a digital format. (The files can be stored on USB memory drives.)
