DESIGN HIGHLIGHT
2.1
AMANERO USB MODULE – Upgraded since 20
th
Sep 2017
The Ares is equipped with the famous Amanero USB Module, with DENAFRIPS redesigned
and optimized circuitry, allow the Ares to be used as high-end DAC with computers /
streamers. It supports 24bit/384kHz PCM data stream, and DSD64, DSD128, DSD256
decoding via asynchronous USB input.
NOTE:
The USB Module is designed to switch on only when USB Input is selected. This is
specially designed to reduce inputs interference for best sound reproduction.
2.2
LOW JITTER AKM AK4118 DIGITAL AUDIO RECEIVER
It is known that the jitter contributes greatly to the sound quality. The use of a low-jitter
digital audio receiver chip is indeed necessary. The AKM AK4118 is currently the lowest
clock jitter digital receiver audio chip available in the market. The Coaxial, Toslink input
support to 24bit/192kHz digital audio format.
2.3
SAMPLING
Depending on the sampling rate of the input signal, the Ares automatically converts it to the
most suitable sampling rate of the R-2R DAC for decoding. Although the R-2R DAC can
decode almost all the sampling rate of the audio signals, but in fact, the actual R-2R
architecture and circuitry design, decided the best sampling rate to sound best that it shall
decode. The use of up-sampling processing converts all digital audio input signal to the
predefined sampling rate, so to ensure all kind of audio format can be decoded with the
best sound performance.
2.4
PROPRIETARY R-2R AND DSD DECODING ARCHITECTURE
The Ares is equipped with 20Bit R-2R DAC to decode PCM data stream and 32 steps FIR
analogue filters hardware decoder to decode DSD data stream. These designs guaranteed
the PCM format can be perfectly decoded, at the same time, the DSD format can be
perfectly decoded as well. It is rare in the currently market that a R-2R DAC can hardware
decode both PCM and DSD formats.
2.5
SIMPLIFIED ANALOG FILTER
The simplest analogue filter makes the audio signal path shorter, avoided the traditional
filter phase shift, lowered the distortion, and achieved higher signal to noise ratio.
The Ares absorbed the mainstream DAC’s technology available in the market, more
importantly, adopted DENAFRIP proprietary technology to made this DAC stand on its own
feet to be the star on its own.
