Audiophonics Alimentation linéaire

Faible bruit USB 5V 2A 25VA / 220V

audiophonics alimentation linéaire régulée

Voici une alimentation linéaire régulée et stable pour tout projet DIY audiophile de haute qualité. Tous les raffinements techniques nécessaire sont incorporés dans cette alimentation dédiée à l'audio et elle s'associera parfaitement à vos appareils HiFi fonctionnant sous 5V (DAC, source numérique...).

Elle comporte un régulateur IRF Hexfet de série 34Z piloté par ampli OP Analog-Device faible bruit et non un circuit intégré. Le filtrage EMI RFI incorporé assure un très faible bruit (ripple) de pollution électrique (- de 30mv). Les composants de cette alimentation sont de première qualité avec des résistances DALE et 4 condensateurs de filtrage BC de 220µf chacune. Un fusible F0.25A 250V assure la protection de l'appareil. Les bénéfices d'une alimentation linéaire de qualité sont une meilleure lisibilité du médium aigu et un grave bien mieux détouré. Ainsi cette solution d'alimentation linéaire régulée développée par notre équipe vient concurrencer des solutions plus onéreuses. 

Équipée d'un boîtier 100 % Aluminium, d'une sortie Jack DC 5.5/2.1mm, de 2 sorties USB, cette alimentation avec un transformateur de 25VA extrêmement stable même sous forte charge vous permettra de tirer le meilleur des éléments audio raccordés.

L'alimentation est livrée avec un câble Jack DC 5.5/2.1mm mâle/mâle avec ferrites de 75cm.

Dans le cas d'une utilisation avec un RaspTouch : Si un éclair jaune apparaît à l'écran, vous pouvez ajuster la tension de sortie de l'alimentation grâce à la vis située à l'arrière de l'appareil, jusqu'à disparition de l'éclair.

Câble secteur vendu séparément.

Achetée pour améliorer mon Raspberry DAC PRO 2,
Je suis ravi du résultat obtenu. Graves mieux tenus, reproduction douce et puissante du spectre, possibilité de monter le volume sans distortion si je compare à l'alimentation de base. Un vrai et grand plus pour moi. Merci Audiophonics

Gives a very natural sound
Comparing the Linear Power Supply (LPS) to an IFI Power X powering my streamer:
A bit more subtleties, details and especially more natural. For example different voices are easier to seperate. Emotions in the music are easier conveyed.
Because music sounds apparently less loud, I can turn up the volume higher, yet without getting any listening fatigue.
These small but important improvements brought by this LPS, makes me want to listen, not analytical but for sheer pleasure.

Best performance/price ratio ever
I recently purchased one of these beauties for a customer who is very sensitive to radiation of all sorts and looked for a noise-free replacement for the switching power supply that came with his Squeezebox Classic streamer.
First I went for the ubiquitous Teradak DC-30 but then found out that all sources to buy one are in China. Looked around some more and was amazed to find that there is a French company selling a similar PSU for even less! The ordering process was hassle-free and straightforward. Took less than a week to have it here.
Unfortunately I had only very little time to check it out, but I really like what I see.
I need to emphasize that I don't consider myself an audiophile, I am more focused on things that I can feel and measure. Therefore, I won't share any audition results and comparisons between this PSU and others regarding the sound quality. Sorry folks.

** Case **
The build quality is superb all over. Nice anodized aluminium case, thick front panel, the back panel is also aluminium, everything fits exactly, it's heavy and solid. Chunky IEC power connector, indicator LEDs on the front (white) and back (green). It's a beauty to behold.

** Inside **
Inside things go on like that. Heavy duty toroidal transformer, massively oversized, discrete rectification, four Nichicon electrolytic capacitors, 4700µF/40V each to reduce any ripple, very clean PCB layout. Not a single wire. No flux residue anywhere, it's just as clean as it could ever be.

** Measurements **
There is not much to say about the output. It's absolutely flat 5VDC with no ripple or distortion whatsoever. Even under load this won't change. I hooked up three Squeezebox Classic with a consumption of around 6 to 7 Watts each. Even though this is close to the maximum specified, the PSU had no trouble serving them all the cleanest power. The peak power drawn from the 230V supply was ~34W so it appears that the PSU will consume around 4W for itself per output used. Haven't had the time to play around with smaller loads but I assume this is in relation to the power demands of the consuming device.
Power factor is close to 0.9 which I consider good, not stellar but a lot better than the typical switching power supplies.
Power consumption is shown with 0.0 Watts on the HOPI meter when the PSU is on but nothing is connected! Wow!
The three outputs are joined together but there is so much power available at any time that the consuming devices won't affect each other. This might be different if one emits extreme amounts of distortion, but then such units are best isolated from others and not supplied on the same power rail. Not a fault of this device in any case.

** More Observations **
The unit produces a good amount of warmth so it should not be used in tight spaces with little air around. It's far from red hot though.
There is a fuse inside, protecting the primary side of the transformer. In case it is blown it's just a matter of lifting the top lid and putting in a new one. However, I would have preferred a more accessible place for the fuse, somewhere on the back panel.
The LEDs are just poking through their respective panel, they are not fixed so it's possible to push them in. All that holds them is their own two legs. Not a major concern though, considering the price this is a tiny compromise.
The USB ports don't have a lot of grabbing force. It is rather easy to pull out USB connectors. A bit more spring tension wouldn't hurt.
Although I ordered only a PSU, there was also a 5.5/2.1mm cable delivered along. Nice touch, guys, and very appreciated!

** Summary **
This is an amazing piece of kit, unexpectedly well-built considering the budget price. I think this little thing can compete with PSUs in the price range of 400 to 500 EUR. Much of that goes into the brand names, not the values inside. A lot of attention was paid here, and all pieces that count are well done.
I will recommend this unit, and Audiophonics overall, to anyone who is interested in enhancing their audio equipment and musical experience.
