DENAFRIPS Ares II Manual

1. INTRODUCTION
Thank you for choosing DENAFRIPS products! The Ares II DAC is a 20Bit discrete resistor
ladder Digital to Analog Converter, also known as R-2R DAC.
The Ares II is built to reproduce digital music in this modern era. The use of advanced
hardware design, powerful digital processing technology, combined with the recording
technology, digital music playback technology experience, to achieve the perfect music
playback goals and accurate music expression.
The architecture uses the most primitive R-2R DAC technology, it is probably the most
suitable architecture to reproduce music. Despite the test results of various measurements
and parameters of the conventional R-2R DAC are usually not as good as the mainstream
integrated DAC chip, but the sound of R-2R DAC, is often filled with emotion, relax, high
resolution, and additive musicality that most of the common mainstream integrated DAC
chip cannot match.
To achieve a decent sounding R-2R DAC, the use of ultra-precise resistors is necessary. The
cost of high precision resistors is expensive, each resistor must be stringently measured and
matched by machine with human intervention to cross-check. These results in a very high
cost in the manufacturing process, hence, R-2R DAC is also a symbol of high-end DAC.
The Ares II employs true balance R-2R DAC design. Each channel is decoded by 4 sets of R-2R
network. This design has very small linear error, high decoding speed, low digital noise, not
only to ensure that the audio signal is low distortion, but also to ensure a very low
background music noise; allow listener to enjoy the true music with dark background.
