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).

Relaxed sound
This product lies outside the general rule “you get what you pay for”. As a standalone dac tested with optical ,coaxial, usb inputs sounds really good. I am not afraid to say it stands close to far more expensive R2R dacs I had the chance to listen to. My ongoing concern with digital has always been the listening fatigue ,this bombarding and exaggeration of microdetails that messes with your brain. This dac is a different story.
The RPI4 is a fantastic streamer transport and with the I2S connection to the dac sounds fantastic. Tidal HiFi in most cases sounds really good. (MQA is not my thing)
I have tested standard 16/44.1, higher sampling rates and DSD. My preference remains standard 16/44.1 and DSD through Volumio.
Being a vinyl fan from my early days and having accepted the pros and cons of this format I got lucky to run into this “desktop” sreamer-dac that gives me 4-6 hours of daily music listening without any fatigue. XLR output to a Luxman L550axII feeding a pair of heavily modified old Klipschorns and there you are !!!
A great combo from the Audiophonics guys!!

Acheté début 2020, j’ai pris le temps de tester l’AUDIOPHONICS EVO-SABRE PACK DIY DAC Symétrique 2xES9038Q2M.
Avec l’entrée USB je suis déçu, le son est moins percutant. Je ne serai dire pour quelle raison, surement ma source USB (Serveur NAS ou Raspberry PI 4) ! De toute façon, je ne souhaitais pas utiliser cette entrée en l’achetant.
Le résultat est meilleur avec le Raspberry PI (interne au boitier utilisant les GPIO en I2S). Le son est dynamique, précis sans être analytique comme les autres DAC Audiophonics DIY utilisant également l’ESS SABRE 9038Q2M. Je pense que c’est lié au filtre a phase linéaire et ou la gestion du DPLL.
J’ai changé les AOP de sortie par des BURSON AUDIO SUPREME SOUND SS OPAMP V6 Classic AOP Simple (pour info, pas besoin d’adaptateur). A mon oreille cela n’a pas changé grand-chose (A l’époque où j’avais changé les AOP j’avais des enceintes et un ampli bas de gamme de 20 ans d’âge).
J’ai mis en place un dissipateur thermique sur le Raspberry Pi 4 qui s’intègre bien entre le PCB et le PI (Geekworm Raspberry Pi 4 11mm Embedded Heatsink (P165-B)). Ce qui m’a permis de gagner quelques degrés.
J’alimente le DAC avec l’alimentation proposé par Audiophonics (MEAN WELL Adaptateur Secteur Alimentation 100-240V AC vers 9V 4A DC ) avec un filtre ifi
J’ai remplacé l’écran de droite SPI par un écran DSI en couleur et tactile de 4,3 pouces (4.3inch DSI LCD Capacitive Touch Screen Display 800×480). J’ai dû le coller avec du double face en façade. Ce n’est pas des plus esthétique (ce n’est pas moche non plus) mais c’est fonctionnel. Je vois les jaquettes, je peux passer au morceau suivant, diminuer ou augmenter le son en appuyant sur l’écran.
Utilisateur de Roon, j’utilise la distribution Ropieee qui s’intègre parfaitement au DAC notamment la gestion du volume, l’écran tactile DSI (non SPI). J’ai testé d’autres distributions, Ropieee tien le haute du pavé avec Volumio en termes de restitution sonore.
Pour info, j’utilise ce DAC comme préamplificateur sur un amplificateur Audio-GD A1 et depuis 3 semaines sur des enceintes Triangle Magellan duetto. Le tout sonne très très bien.
Les plus :
- Rapport qualité prix
- Qualité de fabrication
- Pas mal d’entrées (GPIO(I2S), USB, TosLink, SPDIF, Bluetooth)
- En sortie XLR et RCA
- Module DAC symétrique Double ES9038Q2M
- Possibilité de choisir les AOP de sortie
Les moins :
- RPI I2S : 384kHz / DOP128. J’aurai préféré une liaison DSD Direct 512. Est-ce que c’est possible avec le Raspberry PI ? ou Est-ce lié au FGPA Altera Max ?
En conclusion
Très bon produit en therme de son. J’ai aimé le monter moi-même et le modifier pour mon utilisation (Roon Player). L’intérêt de ce produit est le prix, l’électronique de bon niveau, la flexibilité d’utilisation, mise à jour à moindre frais. Si Apple sort un nouveau protocole Airplay 3 (implémentation dans l’OS) ou un futur Bluetooth 6.0 (via clé USB ou changement du RasPI) vous pouvez mettre à jour après que la communauté est sortie la mise à jour.

A delight for audiophile ears
The unit is easy to assemble, helped by very clear illustrated instructions. The quality of the housing is very good, the aluminium surfaces are beautifully brushed and all parts fit together perfectly.
The sound quality is outstanding, and the display with the large ticker showing the metadata of the music currently playing is also very nice.
The documentation of the DAC functions and the remote control can be found in the article description of the DAC board ("Datasheet Evo Sabre"). Unfortunately, this documentation leaves many questions unanswered and some of the items in the settings menu that are accessible via the remote control are not addressed or are perhaps no longer up to date.
Example: According to the documentation, the Raspberry Pi cannot control the power supply state of the DAC board. But in the settings menu, the item "GPIO Power Control" (not mentioned in the documentation) appears, which, when set to "yes", seems to let the Raspberry Pi shut down the device in a controlled manner.
Conclusion: A beautiful and high-quality device that is a lot of fun. However, the documentation could be improved.

Pure High Level Sound
I'm running it for a couple of months. It's paired with a Trigon Energy Amp through XLR and the sound is amazing! For me is the sound much more better than from the Lindemann Limetree Network and the Lumin D2. I had both of them! I only use the free version of Volumio, because I'm just streaming from a NAS. Even If you are not familiar with PI or DIY give IT a's realy easy!!!

Montage rapide et bien documenté (attention toutefois à la partie écran, pour ma part j'ai surement oublié un film ..)
Très fonctionnel avec sa télécommande, la qualité est au rendez-vous, je découvre des sons qui était quasi inaudible avec mon ancien système.
Un petit bug de son, manque d'intensité au démarrage mais reprend de la vigueur en utilisant le gestionnaire de volume de l'application volumio. Curieux.
Esthétique de qualité.
Je conseille.
