AIYIMADAC A2 Headphone Amplifier DAC Converter Mini Stereo Digital-to-Analog DAC for PS5/PC/MAC Computer desktop Game DAC Amp PC-USB/Coaxial/Optical to 3.5mm AUX RCA Headphone Output 24Bits 192KHzClimatePartner certified

Bought it because pc sound was not great I added this and have much better control in volume. Reasonably priced when I bought it compared to others that were 3x more expensive. For what I needed it does the job

I use an Echo Link Amp combined with a speaker splitter function box and a Belkin AIRPLAY2 Receiver to wirelessly stream my APPLEMusic/AmazonMusic library to my ceiling speakers from my iPhone/AppleTV/Laptop or iPad, throughout our home. Always v happy with the system but for one failing… I was never happy with the quality of the inbuilt DAC chip on the Echo Link Amp. Too neutral. Lacking in sub and mid bass. Too lacking in note weight, flaccid trailing tones and sub-par tone and timbre, and shouty highs. Too little impact. Not meaty or juicy enough! My in-built ceiling speakers being of the very best quality, and not wanting to replace the amp, it made sense to try and find a high value to cost DAC to add to my chain. I can’t quite believe just how much of an improvement this cheap tiny box has made to the music casting throughout my house. Now finally have thump in the bass, clean natural and true mids and sparkly non fatiguing highs. Far more musical, with warmth and body. And the tone controls mean I can dial my preferences in even further. V happy with this inexpensive DAC!

This little thing is nice, well built, has rubber feet on the bottom and has NE3552 opamps, USB micro is used for power only but don't power it via a USB port, use a good 5v1amp or higher(amps) power supply, the volume, bass and treble controls are nice. Came with USB micro for power, USB type A to B and digital optical which was also nice to include. If you want to power more demanding headphones look at something more beefy 12v+ options

Needed something inexpensive to take the audio from a PC and feed it to a HIFI amp or an independent wireless headphone system, without compromising the sound quality. I didn’t expect this DAC to perform well, but given the price, I thought it worth a try; I’m happy to to say it performs far better than I anticipated. It doesn’t interfere with the (already good) sound quality, but gives me an interface to adjust the sound level etc. As a bonus it can be (and is) powered by the PC usb port so switches on and off with the computer.

It seemingly stopped working a week after using it, when you turn it off via the turning volume all the way left, it doesnt register the clicks properly it seems so keep turning the volume on and off till it turns itself on.. or just return it like I will do if it keeps happening.. Otherwise it is pretty good, not very loud but good volume for PC

been using this DAC with my akg k361 as they sounded horrible and flat using the standard headphone port on my laptop. Favourite feature of this device is that is USB powered this comes as a positive and negative i have a limited amount of plug outlets and i travel often with my laptop so having this use 2 USB ports is a better option for me although i noticed one issue but i soon realised it was user error and it looks to be the same issue some people are putting for this device in the reviews saying that it doesn't power on or makes a hissing or buzzing sound.The sound problems are to do with the USB power if the device has insufficient to resolve this try powering the DAC with a different USB port and avoid using USB hubsOther issues that could cause sound problems is the USB that provides data could have limited bandwidth and may need a full port to itself i recommend using a USB 3.0 port (Blue) as this would most likely solve the issueIf the device is making a hissing sound another device is causing interference i have a Laptop fan cooler connected to my laptop to keep the device from thermal throttling and if i plugged the DAC into a port on the cooler or near the cooler it would cause interferenceIF all else fails then it could be faulty or the device attempting to power the DAC is not outputting enough power or is disabling the port due to the power on start-up i would advise leaving the DAC ON as it can cause all the usb devices connected to the computer to turn off and turn back on this could cause corruption to USB drives if they were actively transmitting. I wouldnt fault the manufacturer for this as its a USB device and thats the sacrifice for it.

As mine didn't work, with any of my headphones (over the ear/back of the head/in ear buds) I have no way of knowing about the sound quality. All I CAN say is that it is solidly built, metal rather than plastic, rather like a micro guitar effects pedal. A balance control between the L & R channels might be a useful addition. for those of us who have hearing damage to one or both ears.

More than happy with this item. I like it's small form factor compared to that of other DACs.The bass and treble adjustment features are a nice addition and they really do work.This item is pretty much the same thing as the Fosi Audio Q4 and the Nobsound Q3 but at a much better price, so if you've been looking at them I'd definitely recommend you go for this one.Overall excellent for it's price, absolutely no complaints.Edit - price when purchased was £36.99

Le Dac-A2 de Aiyima est un chouette petit dac, très compact, bien fabriqué et assez lourd, ce qui est souvent bon signe en électronique.Alimenté en 5 volts par micro-USB, ce dac a un profil sédentaire mais l’alimention au travers du PC le rend finalement assez mobile. Petit précision de suite, le branchement de l’alimentation sur une alim standard charge rapide s’est tout de suite traduit par un sifflement très désagréable, celui-ci a immédiatement disparu après branchement de l’appareil sur un pc doté d’une alimentation de qualité. Ainsi branché, l’appareil apparait totalement silencieux, aucun buzz désagréable ni sifflement perçu par la prise casque. Très bon point donc.Le bouton de volume sert également d’interrupteur, voici donc un dac qu’il est possible d’arrêter totalement. Les boutons de basse et d’aigu sont de bonne fabrication, en aluminium, ils sont légèrement crantés ce qui permet d’être précis.La petite molette pour sélectionner la source semble également de bonne qualité.Le dac peut être branché en USB (96KHZ max) Coax ou optique ( 192KHZ dans ce cas), l’installation est automatique sous windows 10.La prise casque est de bonne qualité, la puissance dispo semble bien présente même si mon casque (Phillips X2) ne représente pas vraiment un challenge à ce niveau.La sortie RCA couplée à un Aiyima A07 permet un contrôle des niveaux bien pratique.Niveau rendu sonore, peu de chose à dire, je ne vais pas me lancer dans une grande envolée lyrique, je dirai simplement que le rendu est très droit, sans exagération aucune dans un des registres du spectre sonore, ni agressivité, ni rondeur excessive.Un bon petit dac, pas cher du tout, largement recommandé même en utilisation semi-mobile ( ordinateur portable). J’aime !

Sehr gute mechanische Verarbeitungsqualität. Ich nutze das Gerät um die Soundkarte meines Laptops zu umgehen. Das funktioniert (mit WIN 10) auch auf Anhieb. Die Klangqualität ist wesentlich besser. Und nebenbei habe ich auch noch das Problem mit den Knacken beim Abspielen über mein Musik Bearbeitungsprogramm gelöst.Auch das integrierte Klangregelteil (Bässe/Höhen) funktioniert super. Alles in allem eine sehr klare, durchsichtige Klangqualität. Ich nutze das Gerät in Kombination mit einem Aktiv-Lautsprechersystem von M-Audio.Das direkte Umschalten von Kopfhörer auf Lautsprecher funktioniert auch einwandfrei: Klinkenstecker Kopfhörer rein und nur noch Audio Signal auf dem Kopfhörer ohne irgendwas umschalten zu müssen.Von meiner Seite sehr zu empfehlen!

Ancora una volta all'Aiyima, come del resto fanno con molti dei loro prodotti, grazie al rapporto qualità/prezzo hanno azzeccato un best-buy! Il packaging come sempre è molto curato e con una grafica personalizzata per nulla anonima, il prodotto arriva ben protetto e fornito di cavo ottico, cavo usb A - usb B, cavo per l'alimentazione extra usb A - micro usb B. Benché possa assorbire la corrente necessaria dal collegamento usb che userete per l'input audio ad esempio dal pc, noi vi suggeriamo di alimentarlo con un alimentatore extra da 5v tipo quelli per smartphone, tramite il cavetto incluso nella scatola, in modo da evitare possibili interferenze statiche, che a dover di cronaca comunque, noi non abbiamo mai sentito arrivare all'amplificatore e di conseguenza ai diffusori; il controllo toni è stato molto utile per apportare quelle variazioni al suono delle frequenze, che si potrebbe voler apportare a seconda dei gusti personali di ascolto, ma allo stesso tempo il controllo toni non è mai stato troppo invadente al punto da "colorare" in maniera troppo artificiosa il suono originale; non ci sono op-amp da poter sostituire, come invece avviene per l'ottimo amplificatore sempre dell'Aiyima A07 di cui vi invitiamo a leggere la nostra recensione alla pagina del prodotto, ma per il tipo di lavoro che svolge il dac non ne abbiamo sentito la mancanza. abbiamo provato a sdoppiare il suono in uscita dalle connessioni rca tramite dei semplici cavi ad Y verso un altro amplificatore per cuffie che potesse sopportare cuffie con un impedenza molto alta come le Beyerdynamic dt990 (600 ohm) ed anche in questo caso il dac non ha fatto alcuna piega ed abbiamo apprezzato ancor di più il controllo toni in quanto queste straordinarie cuffie in questione sono note per riprodurre delle frequenze alte davvero taglienti, e con il controllo dei toni abbiamo potuto godere del suono delle Beyerdynamic ammorbidendo gli alti quando diventavano davvero troppo fastidiosi. Se qualcuno fosse interessato ad usare questo dac per collegargli via usb un raspberry utilizzando il software Volumio oppure MoodeAudio, sappia che non è possibile utilizzare dalle impostazioni il controllo volume via Hardware in quanto il chip del dac (come del resto molti altri dac con questo chip) non è riconosciuto da questi sistemi linux-based; o usate una scheda I2S con uscite digitali (come la hifiberry Digi+) per collegare il raspberry al dac oppure impostate una regolazione volume via software oppure escludete la regolazione volume dal raspberry sempre nelle impostazioni dei due player citati, demandando così solo al dac il controllo volume in maniera manuale; il potenziometro del volume nella funzione di preamplificatore del dac è impeccabile, lineare, e non introduce verso l'amplificatore nessuna distorsione o rumore neppure al massimo della sua scala; cosa che invece non è stata possibile con un prodotto simile della Fosi Audio il quale è stato restituito in quanto al variare del potenziometro del volume introduceva fastidiosissime scariche statiche ai diffusori; Pertanto il dac della Aiyima nella sua circuiteria è ottimamente congeniato.in conclusione ci sentiamo serenamente di consigliarne l'acquisto in quanto lo abbiamo trovato assolutamente soddisfacente e adatto ad ascolti di qualità, soprattutto se affiancato all'amplificatore Aiyima A07 con la quale crea una combo con un rapporto qualità/prezzo davvero eccezionale e difficile da battere per altri prodotti della stessa fascia !

It lacked the AMP power to drive my Hifiman Sundara headphone to a satisfying level for me even at max volume and gain, and even if it did you also probably wish to have some headroom as well. I had no issues with the sound quality during the brief time I used them and the knobs worked fine and there was no audible hissing when no sound was playing. Would have liked to see a "notch" in the tonal control knobs that was set to zero since so you can tell if you were right at the +-0 dB bass and treble setting. For the price it is hard to complain.

Petit DAC très étonnant, utilisé entre un lecteur de CD NAD C516 BEE âgé de 10 ans (sorties optiques ou coaxiales SPDIF) et, par les sorties RCA du DAC, un préampli QUAD 44 upgradé, associé à un QUAD 405 upgradé avec alimentation à découpage, plus deux CABASSE SAMPAN 311 âgées de 44 ans !!! Le son est très bon, l'impression d'être devant les musiciens est surprenante. La gigue est pratiquement inexistante. La puce embarquée est une Cirrus 8416, d'après l'annonce du négociant. D'autres matériels similaires ne proposent que la puce Cirrus 8412, qui est obsolète. Attention donc !Pour le prix, ce mini-DAC est fantastique !!!!!!!C'est également un des rares DAC du marché à proposer un réglage du volume, des aigus et des graves. Ces réglages sont précis. Les potentiomètres sont de bonne qualité.On peut également utiliser ce mini-DAC sur la sortie optique SPDIF d'un téléviseur HD, associé par un cable HDMI à un lecteur de DVD, et les relier par les sorties RCA du DAC à une chaine HIFI. Là encore, le résultat est bluffant !Ce mini-DAC est aussi USB. On peut donc l'utiliser pour récupérer le signal numérique disponible sur les prises USB d'un ordinateur, soit comme ampli casque, avec une grande différence de qualité en comparaison avec le signal analogique disponible sur la prise audio 3,5 mm, soit vers une chaine HIFI.Un réglage des paramètres de l'ordinateur peut être nécessaire. Par ailleurs, en l'absence d'une liaison optique (donc isolée électriquement) entre l'ordinateur, le DAC et la chaine HIFI, une inversion des masses électriques peut apparaitre et empêcher le fonctionnement. Dans ce cas, il faudra débranchez l'alimentation de l'ordinateur. Ce problème est commun à d'autres DAC.L'alimentation NEUE DAWN Chargeur USB C 5,1V 3A Type C Adaptateur Secteur pour Raspberry Pi 4 à 14 € vendu sur Amazon est parfaite pour alimenter ce DAC, et ne fait aucun bruit, ceci si une prise USB A n'est pas disponible a proximité.En conclusion et pour un prix minime, ce mini-DAC apporte une grande amélioration acoustique, supprime une grande partie de la gigue inhérente aux DAC obsolètes embarqués dans les lecteurs CD bon marché, de bas ou moyenne gamme, et fera redécouvrir les grandes qualités d'enregistrement des CD.
