ALLO DIGIONE SIGNATURE

Digital interface Raspberry Pi / Dual power supply / NDK clock


Digione SIGNATURE ALLO BOSS


The Allo Digione interfaces are currently the best  SPDIF /digital outputs for Raspberry Pi. They connect directly to the RPI by GPIO and provide digital transfer while correcting the jitter found in any ordinary SBC. This interface also provides the RPI with a 75 Ohm BNC and RCA Coaxial Digital 24bit 192khz output. Its rise time is 1 ns and the voltage completely meets the coaxial / BNC standards (550mV coaxial). This interface is capable of transforming a digital limited source such as an SBC into a true high-fidelity device with a remarkably low jitter of 400fs.

For this SIGNATURE version the Digione interface team added latest type of NDK oscillatorrs iultra low jitter and phase noie. The audio circuitry also hosts a supercapacitor to enhance the power supply and to provide partial protection in case of sudden voltage off-state.

Review by The Hans Beekhuyzen Channel



Two insulated PCB


The PCB is now divided into two parts, allowing the circuit more space than the previous version.

Its design is less subject to space limitations and can accommodate compex network and more subtle components than before. Clocks and buffers enjbenefits from better film capacitors.

allo two power supplies


In addition to this first advantage, the choice of dividing the two PCB is mainly explained by a desire to overcome the technical limitations (power supply management) in a Raspberry Pi .

The lower PCB and has its own standard power input (5V / 2-3A). This power supply is also used to power the PI.

The lower PCB working in duo with the RPI is the "dirty side" which gathers every component that may generate unwanted noise or cause signal degradation.

Naturally, this "dirty" portion is isolated (galvanic insulation) from the rest of the circuit  that is dedicated strictly to audio processes.


On the other hand, the upper PCB is the "clean side" which  focuses all critical and high sensitivity components. This circuit is isolated from the second PCB and Pi. It can (and must) be powered separately.

If the prospect of a double power supply for one interface can seem restrictive, the return on investment is considerable:
The "clean" power is extremely flexible. Since it only bear sensitive audio components, the technical specifications that it has to meet are less heterogeneous. It is much easier to achieve satisfactory operating conditions with this type of configuration. The circuit will operate without failures with voltages from 5 to 6V as long as it is provided with at least 100mA current. Whether a battery, a linear power supply or even a good switching power supply is up to you.

The second , more subtle, benefit is also the most interesting in the  context of an audio project.

The  2x PCB / 2x separate power means that any improvement in the "clean" circuit power supply will be an  improvement of higher repercutions than with a single-supply scheme.

In other words, the Digione Signature interface will not "waste" the potential of an improved power supply on components that do not specifically need the best power supply there is. Thus it can focus especially on the critical audio components.

The design 2PCB / 2PSU is able to make the most olf any improvement made on the upper floor power supply. Conversely, the digital interface is more likely to "forgive" the user if the power on the "dirty" side is not as good as it could. This asymmetry is very relevant in audio with multi-PSU systems.

Super streamer for DIY audiophiles
The ALLO DigiOne Signature does one job and does it very well: streaming music from your network (via WiFi or Ethernet) to your DAC via an SPDIF Coax interconnect.
That said, if you buy the add-on board separately you will have a bit of work mounting it on the Raspberry Pi, putting it in a casing, setting up and configuring the software. So being handy with your hands and flashing SD cards is hardly recommended.
I set mine up with ROPIEEE - they have great instructions on their site. And it is important to follow their recommendations for the size of the SD card.
I also bought an IFI 5V DC power supply for the clean power.
The result is remarkable and the satisfaction of putting this together yourself is even greater.
I highly recommend the ALLO DigiOne Signature.

Quel bon en avant...
Après une quinzaine de jours à profiter de cette nouvelle version de la Digione, je dois dire que cette version Signature fait un gros bon en avant par rapport à la première version.
Alimenté par deux alimentations dont une à très faible bruit comme le recommande le fabriquant, l’écoute est plus claire, aérée. La scène est plus ouverte, ma salle d’écoute s’est agrandie ;-) . Le bas du spectre est bien charpenté, précis, avec de l’impact et un abaissement en fréquence audible et bien réel.
De même, pour le reste du spectre, il me semble que tout est très bien maitrisé. Pour les hautes fréquences, c’est pareil, net, précis avec beaucoup de détails.
Bref, cette version signature est un vrai régal à l’écoute. J’avais des réticences à remplacer la première version que j’avais bien aimé, mais je dois avouer que cette version Signature est vraiment un ton au dessus à tous les niveaux. A préférer donc à la première version sans hésiter…

Porte bien son nom
Clairement meilleure que sa petite soeur, restitution plus fluide et avec davantage de relief.
Par contre je conseille de soigner l'alimentation , tant au niveau de la partie "dirty" que de la partie "clean".
Je l'ai associée à un RPI B+ et comme OS j'ai installé Archphile.
La restitution est un poil meilleure en mode mpd direct qu'en passant par l'upnp.
