EVO DAC Sabre audio circuit

Double DAC ES9038 integrated in balanced mode


The EVO-Sabre is a high-precision DAC using two 32-bit ES9038Q2M Sabre chips integrated in dual Mono mode: each of these chips see its computing power 100% dedicated to a single channel of the stereophonic signal. This achieves a sound restitution of exceptional clarity with tremendously low crosstalk.

This component belongs to ESS flagship series and is among the best current hardware solutions for high-fidelity audio decoding. It uses HyperStream 32 BIT 768kHz architecture with native DSD support. Each one of this chips is also equipped with advanced reconstruction filters and uses some of the finest dithering techniques available on the audio market.

ESS ES9038Q2M SABRE DACs are also very popular thanks to their ability to operate volume with almost no consequences on the audio bitrate.

The board works in balanced and single-ended mode and offers both a balanced stereo output on 3-pole XLR connector and an single-ended stereo output on RCA connector. The module can thus be ideally suited to most integration scenarios and will easily find its place in minimalist audio projects as well as in very complex Hi-Fi installations.

XMOS U208 USB Interface


The USB-B input (USB-2) works with a XMOS U208 USB interface. This is a reference component in the field of high-fidelity music, with digital streams supports up to 32-bit 768kHz as well as (native) DSD512.

Definitely designed for high-resolution, this asynchronous USB interface has a computation capacity of 1000 MIPS all of which is dedicated to the processing of your digital audio signals with minimal jitter and noise.

When the DAC EVO-SABRE is used in conjunction with a Raspberry Pi, this high-definition USB input allows to immediately interface digital audio streams to RPI I2S up to 384kHz / DOP 128.

FGPA Altera Max


Unlike its predecessor, the EVO-SABRE has several inputs driven by an independent interface.

SPDIF signals are handled by a FGPA Altera Max capable of performing clean processing of the digital input streams. These digital signals are interfaced in I2S to each of the two DAC chips, which represents a significant gain in performance compared to previous generations.

The SPDIF inputs support PCM signals up to 24/192 as well as DSD 128 DOP streams.

Microcontroller autoconfiguration


Thanks to an integrated microprocessor, the EVO Sabre automatically detects the format & the sampling rate of the signal source and will automatically adapt its configuration to provide the best listening performance without requiring any user intervention.

This control by CPLD chip maintains great stability while preventing decoding problems as well as the appearance of audio artifacts.

It also enables a continuous decoding of playlists with heterogeneous file types without having to worry about reconfiguring the DAC to benefit from optimal audio quality.

RaspDAC EVO interface



Dual Screen


The kit comes with two separate screens. The EVO SABRE audio circuit display (left) is a 1.3 "128X64 OLED screen. It simultaneously displays the active input, the sampling rate and the volume as defined by the DAC ES9038Q2M chip controller. This first display is useful to check in real time that the processing of the audio files is going as planned and in the best conditions.

A second 3.12 "256x64 OLED screen is connected to the Raspberry Pi (if present) in SPI (CN4). This secondary display can retrieve in real time the playback data at the software level (Dietpi / LMS) in a similar fashion to what our RaspDac Mini already do. This function requires that the EVO uses one of our custom distribution or that the user uses a custom display script. 

Front controls

A switch located on the front panel allows to turn on / off the system properly while preserving the integrity of the storage media (OS on SD card in a Pi & hard disks). It is backlit when the module is in stand-by mode but powered to indicate that the circuit is ready for operation.

The rotary encoder on the far right is directly connected to the volume control of the DAC chips. It allows easy and precise volume adjustment the from the device front panel.

I/R Remote control


The infrared receiver communicates both with the microcontroller in charge of driving the DAC chips and with the Raspberry Pi if the EVO-SABRE is used in network drive mode with LIRC configured. The remote control (included) thus centralizes most of the playback functions for great ease of use.

The input selection, volume and standby functions, as well as the filters adjustements are handled by the integrated microcontroller, while the play / pause, previous / next functions are transmitted to the RPI (requires LIRC configuration on GPIO 04)

Web App / LMS


Used in conjunction with a Raspberry Pi 4, the EVO-SABRE ES9038Q2M becomes a complete dematerialized streaming solution, capable of running the best network streamer / playback solutions. This opens up a lot of options for controlling the device (playback, recovery of audio files on a NAS, online streaming service) via the network (simple web browser accessible from any connected object, dedicated applications, or your own scripts) to cover the full spectrum of possibilities and realize the full potential of your audio installation.

The pinout is the most common, compatible with the RPI-DAC driver and present in all distributions.

It is also possible to use the driver for the I-Sabre 9038, found in the Raspberry PI kernel from version 4.19.34. 
This function allows access to the parameters of the DAC chips (volume, hyperstream parameters, filters) directly via the RPI and its softwares interfaces (in addition to access via remote control and controls on the front of the device).

RaspDAC EVO housing

The RaspDAC EVO kit is delivered with its dedicated custom box. The latter is machined from 100% aluminum, a light, robust material that blocks any interference that may affect the audio.

The housing is pre-drilled (spacers and connectors). Its assembly comes down to fixing the various panels using the supplied hardware.

Rear panel

Ports audio Sabre Evo Audiophonics

From left to right, the connector panel has a balanced XLR output as well as an unbalanced RCA output.

Then there are the digital inputs of the DAC with coaxial connector, optical connector, USB-B input and bluetooth antenna.

Finally, the connector panel is equipped with a Jack DC input dedicated to the power supply, then the RPI 4 connectors (RJ45, USB-3, USB-2, HDMI video output as well as connector for SD card dedicated to the operating system. ).

Both outputs (RCA & XLR) are active simultaneously.

The rear cover of the supplied housing is drilled to match the connectors of the RPI 4.

Optimized power stage


Powered by a DC 9V jack connector, the module operates from a particularly well designed power stage which allows to ensure a stable signal while reducing residual noise.
For this purpose, the PCB has a Mornsun DC / DC converter followed by two voltage regulators 79M08 / 78M08 dedicated to the analog part with is powered with +/- 8V.

The card has a separate 5V power stage dedicated to the Raspberry Pi. In this scenario, the RPI is supplied directly via its GPIO port, avoiding the need to add more connections and cables. Every configuration uses the minimum amount of cables for increased ease of use.

The card also has Ultra low noise voltage regulators dedicated to the conversion stage in order to isolate the DACs from the main power supply.

The DVCC voltage is generated from an LP5907 (regulation <6.5µV), which generates the DAC 1.2V Vref which is a critical voltage.

The AVCC voltage is generated from a dedicated ADP150 regulator (regulation <9µV).

Superbe DAC
Je l'ai pris pour servir de DAC via RJ54 et surtout pour améliorer ma platine CD en sortant en coaxial.
L'amélioration est nette au niveau de la spatialisation et aussi du rendu de grave !

Cerise sur le gâteau, les web radio via moode et je commence à mettre les mains de le cambouis avec DietPi qui offre plein de possibilités.

Le boitier ultime ?
Cela faisait quelque temps que je cherchais un lecteur réseau/préampli/DAC avec quelques caractéristiques spécifiques:
- sorties XLR
- lecteur réseau "open-source", ici avec un Raspberry
- DAC de qualité
- pilotable via télécommande

Je dois dire qu'au vu de la fiche technique, ce modèle était idéal. De plus, chapeau à Audiophonics, vous montrez les mesures et faites tester certains de vos produits sur Audiosciencereview. A l'heure où nombre de marques audiophiles ne montrent quasiment pas de mesures, ça fait plaisir.

Ma chaine hifi: enceintes amplifiées Rowen AT1 (les ancêtres des PSI A215M), lecteur CD usb Asus Impresario, platine vinyle Stanton ST150 (sorties SPDIF). Il faut dire que les enceintes sont très précises et ne pardonnent pas un mauvais maillon.

L'assemblage: est relativement facile pour une personne comme moi qui a déjà monté des ordinateurs. Il y a eu une erreur de vis (la mauvaise dans le sachet) mais c'est entré en ordre avec Audiophonics facilement (très bon service d'ailleurs)

La finition du boitier respire la solidité. c'est beau, on a envie de le mettre en avant. Rien à dire.

La configuration du lecteur est facile, mais étant habitué au monde Windows en X86, allumer et éteindre un ordinateur se fait souvent à chaque utilisation. Ici j'ai eu le souci qu'en gardant cette habitude, le système d'exploitation ne fonctionnait plus au bout de quelques jours. J'ai donc changé la physolophie et je laisse le DAC H24 allumé. J'ai installé l'image Volumio modifié par Audiophonics, cela marche impeccablement.

A utiliser c'est très facile, le produit se pilote facilement. L'utilisation à la télécommande fonctionne très bien.

Le son ? Rien à dire. Il suffit de voir le test sur Audiosciencereview pour voir que ce DAC est très bon. Gros avantage: j'ai littéralement aucun souffle provenant du DAC. Il faut vraiment coller les oreilles aux enceintes pour entendre un petit frrrrrr mais c'est du aux enceintes.

Deux points d'améliorations à mon gout:
1) pouvoir dimmer la puissance des écrans
2) ce souci étant lié à la plateforme raspberry et Audiophonics n'y peut rien: avoir un stockage en SSD via connexion PCI-E. En esperant que le prochain Raspberry 5 le fasse et que son format soit au milimètre près le même que le 4 pour facilement upgrader. En effet, le stockage via micro-sd est assez lent.

En résumé: un excellent produit au très bon rapport qualité/prix.

Produit exceptionnel.
Il diffère des auteurs DAC par une qualité sonore supérieure. Grâce au FPGA ALTERA MAX2 avec deux cristaux 44,1x et 48x. supprimer le jitter des entrées USB, Raspberry PI ou Bluetooth.
De nos jours, c'est un grand avantage d'avoir un DAC avec entrée IP sans jitter. Avec radio Internet et musique NAS.
C'était très facile à faire pour moi.
