Antipodes DX

Antipodes DX Music Server. The heart of the DX is a motherboard featuring a quad-core Intel Atom processor and 4GB of DDR3 RAM, the latter to cache the selected playlist for direct playback. According to Antipodes' founder, Mark Jenkins, the transfer from long-term storage to RAM is managed "in a better and more consistent way, which does improve sound. Exactly how the files are placed into RAM and read out of RAM to the audio output is very important to the sound quality."
