Antipodes Audio K21 Music Server




K21 Music Server

The Antipodes K21 is the latest evolution of the Antipodes DX. Compared to the DX3, the K21 is faster and more dynamic, at the same time as providing greater detail and refinement. The K21 can be used as a very good Server-Player, running both Server apps and Player apps. It can also be used as a Player only, running just Player apps, teamed with the K41 running the Server apps, for exceptional performance.

We will be asked this question, so we will answer it now. The K30 will outperform the K21, in terms of sound quality. But a K41+K21 will, very decisively, outperform the K30. The K41+K21 compares more directly with the USB output on the K50, and which of these sounds better depends on the quality of the extra cables that you will need with the K41+K21 solution. But the K50 Digital Outputs remain the best sound quality option.

The K21 offers an excellent entry point to high-end computer audio, at well below the cost of a K30 or K50, and offers an easy upgrade to the top level by adding a K41 later.
