The DENAFRIPS Ares DAC is a high-end audio device designed to convert digital music signals into analog sound with exceptional fidelity. At its core, the Ares is a 20-bit/384kHz discrete resistor ladder Digital-to-Analog Converter, commonly known as an R-2R DAC. This architecture is chosen for its ability to reproduce digital music in a way that is often described as more emotional, comfortable, and transparent than what is typically achieved with mainstream integrated DAC chips.
The primary function of the Ares DAC is to take digital audio input from various sources and convert it into a high-quality analog signal for playback through an amplifier and speakers. It is engineered to handle a wide range of digital audio formats, including both PCM and DSD, ensuring compatibility with most modern digital music libraries.
The Ares utilizes an advanced hardware design and powerful digital processing technology to achieve its goal of perfect music playback and accurate music expression. The R-2R DAC architecture, while sometimes yielding test results that appear less favorable than integrated DAC chips in conventional measurements, is highly valued for its sonic characteristics, which include high fidelity, transparency, and a unique musicality.
To ensure optimal performance, the Ares employs ultra-precise resistors within its R-2R network. These resistors are meticulously measured and matched, first by machine and then cross-checked with human intervention, a process that contributes to the device's high manufacturing cost and its status as a high-end DAC.
The Ares features a true balanced R-2R DAC design, with each audio channel decoded by four sets of R-2R networks. This design minimizes linear error, enhances decoding speed, and reduces digital noise, resulting in an audio signal with very low distortion and a remarkably low background music noise, allowing listeners to experience true music against a "dark background."
For digital audio input, the Ares is equipped with an Amanero USB Module, which has been redesigned and optimized by DENAFRIPS. This module allows the Ares to function as a high-end DAC when connected to computers or streamers. It supports PCM data streams up to 24-bit/384kHz and DSD decoding (DSD64, DSD128, DSD256) via its asynchronous USB input. A notable feature of the USB Module is that it only activates when the USB input is selected, a design choice aimed at reducing interference from other inputs to ensure the best possible sound reproduction.
The device also incorporates a low-jitter AKM AK4118 digital audio receiver chip for its Coaxial and Toslink inputs. Jitter is a significant factor in sound quality, and the AKM AK4118 is recognized for having one of the lowest clock jitters among digital receiver audio chips available. The Coaxial and Toslink inputs support digital audio formats up to 24-bit/192kHz.
The Ares automatically adjusts its internal sampling rate to the most suitable setting for the R-2R DAC based on the input signal. While R-2R DACs can decode nearly all audio signal sampling rates, the specific R-2R architecture and circuitry design determine the optimal sampling rate for the best sound. The device employs up-sampling processing to convert all digital audio input signals to a predefined sampling rate, ensuring consistent high-quality sound performance across various audio formats.
A proprietary R-2R and DSD decoding architecture is central to the Ares. It uses a 20-bit R-2R DAC for PCM data streams and a 32-step FIR analog filter hardware decoder for DSD data streams. This dual-format decoding capability is a rare feature in the current market for R-2R DACs, ensuring perfect decoding for both PCM and DSD formats.
The analog filter section of the Ares is simplified, resulting in a shorter audio signal path. This design choice helps to avoid traditional filter phase shifts, reduce distortion, and achieve a higher signal-to-noise ratio, contributing to the overall clarity and purity of the sound.
The Ares DAC is designed for ease of use, with a straightforward installation and setup process. The front panel provides clear controls and indicators for its various functions.
While the manual does not detail specific user-level maintenance procedures, it does provide important information regarding the device's longevity and support:
