Might have to take a look at this myself...

Lightweight OS, unnecessary daemons and services are removed
Standard Linux distributions are designed for running servers or for desktop usage. This distribution is designed only for quality audio. So we have removed unnecessary services and daemons that comes with standard Linux, because they have effect on audio quality. For example, in standard Linux distributions you have printing and some other network services running in background. These services use your CPU and memory, and they are not necessary for audio reproduction. You don’t need printing drivers and services for playing music. Because of that, we have removed all unnecessary software from this distribution that can degrade audio.
This distribution comes with lightweight XFCE desktop environment and highly configurable and low resource X11 window manager called Fluxbox. XFCE is easier to use, but Fluxbox is more faster, lighter and less resource demanding. It’s my choice for more than seven years now.
