A DAC is something that transfers the 0s and 1s into the music that we hear and love, from digital to analogue. The reason for this is quite simple and that is that my iMac does not have a good enough sound card or internal DAC. My computer is an iMac from mid 2010 and one thing that always annoys me is that whatever programme I use to listen to music with, be it iTunes or VLC player, it never sounds nearly as good as one of my sources, even with a good amp you can tell it could be better. The earphones I will be using will differ, right now I am using my Heir Audio 4.Ai but I always swap and change. This is for a few simple reasons, it has loads of memory and all my music is on there, it is mainly in low compression FLAC and I will be on my computer for whatever I am doing. When I am at home I will listen to my music on the computer.
