D03 Bluetooth 5.2 Digital Amplifiers 150Wx2 Stereo HiFi 2.0/2.1 CH Desktop Sound Amplificador 24Bit/192kHz Class D Power Amplifier USB DAC Coaxial Optical OLED AptX Support Subwoofer

Low cost, versatile with digital and line inputs for streaming sound from digital sources to passive speakers. I use mine for streaming music from Amazon Music, internet radio (eg Radio Paradise - Mellow Mix) or my store of CDs on my NAS Drive. It's also good at enhancing sound from TV or network Video. I use mine with a Beelink Mini Pc as source via USB or LG TV via Toslink in a bedroom setting using Mordaunt Short M10 bookshelf speakers. By careful adjustment of tone controls I have managed to achieve a full stereo output at either low or higher volume, depending on time or mood, which is full, focussed and extended. (Nah, I'm just trying, badly, to seem like a hifi buff. To be honest, with a nice set of small speakers in a small room context, it makes music and video sound really good at a modest cost. )

Was looking for a small form amplifier to hook up to my TV via optical port to drive a couple of large speakers. I had a much cheaper Nobsound unit doing the same job but it didn't have a remote control feature or the optical input. This amplifier is well up to the job and sounds and looks great. The display is quite small so hard to read this at a distance, but can't really expect it to be any bigger on such a small unit. I did experience an issue with the remote control whereby the volume buttons (particularly volume down) were working intermittently or not at all. I contacted AIYIMA via the Amazon product page and received a response right away. They shipped me a replacement remote control which on receipt confirmed that the original remote was faulty. From a customer service point of view, I was really pleased with the support recieved and hadn't been let in a position whereby I'd have had to return the product for refund or needing a full replacement. Thanks team AIYIMA 😁

A pretty good solid digital amp. I use it with my desktop system. Great connectivity options and having a remote control is a bonus. Sound is good but a little neutral. Overall, I'm pleased with it.

Disappointing performance, clipping, awful tiny menu, sounds FAR worse than the signal from the bluetooth on my phone to my old amp which didnt even have any processing and thats running over USB with supposedly up to 192KHz. I wouldn't waste your ears on this rubbish, I have the a07 pro and was using it with a topping DS10 and in everyway it blew it out of the water, I thought this could replace them but how wrong I was going straight back and although I sadly already sold my Topping DS10 I still have the amp and ordered a better DX5II DAC from Topping which can take optical, the only reason I bought this. I won't buy another Aiyima product though if this is the standard they produce at well over £100.

I'm not a hifi nerd, but I definitely don't like all-in-ones and bluetooth speakers around the house. To my ears, this is great. My first dip into these tiny Chinese no-name amps, I did do a bit of research and Aiyima seemed to be one of the better brands. I needed optical since my system is based off a Wiim mini (amazing device) for Airplay. Not many of the cheap amps had optical, this does. To give a comparison, I was coming from a (massive) Panasonic SA XR 700 amplifier, one of the early big-name amps and one which people still rate highly. I could never love the sound, it was so clinical, so detailed it could be exhausting. I realise that's a plus for some, what I love about this Aiyima D03 is it has a pleasant warmth to it. I don't care about looks with something this tiny, but it looks fine, the remote's fine, I never use it since I use my iPhone with the wiim. It has bass and treble controls. One of the best things is it's so tiny it sits on top of my speaker (Q Acoustics 3030i, works great with them), and barely uses any power at all on standby. A plus in these times.

lovely little compact Amp with plenty of connection options, mainly bought for Bluetooth for my projector and TV sound, I'm happy with it, its running an old pair of mission 782's with no problems, and a mk acoustic pro sub

Fab little amp with plenty of power, bought for use in a 4.5m x 3m gazebo for a wedding. Used with B&W 602 speakers. Plenty of power and punch, had been worried about depth of sound and bass level, but this little amp was brilliant and not used at anywhere near full volume. Bluetooth connection was straightforward as was cable provided for laptop. Did exactly what I needed it to do and will be used for further outdoor parties/events.

Film and music great sound reproduction great clarity and stereo imaging along with superlow bass excellent product.

The Aiyima D03 amplifier arrived yesterday, it was literally out of the box and a plug-and-play operation. It has a very clean and balanced sound and a remote control with which I can adjust volume, bass, and treble. The amplifier is very responsive and connected to my desktop computer. Since the streaming service I use can offer a greater bit-rate than my computer's internal DAC, this amplifier with its 24-bit/192Khz DAC is a very nice match to get the most out of my streaming system. The unit came complete with USB and optical cables as well as a power supply. I drive a pair of B&W dm601's with the amplifier and a JAMA active subwoofer. I have also connected the amplifier to a pair of B&W dm603's with a pleasing sound and no problems at all driving these larger floor-standing speakers. I have no hesitation in recommending this d-class amplifier. In the picture the Aiyima D03 and the Behringer microphone pre-amp for my video conferences (everybody sounds as if they are in my study!)

Pour info, j'en suis très content, super toutes les entrées, pour ma part fonctionne bien avec l'USB sur. Windows 11. Également en bluetooth aussi, Essais avec qobuz et petites enceintes de mini chaine anciennes Kenwood. Je vais le mettre sur mes kef mais je n'ai pas les bonnes longueur de câble. Hâte de l'écouter sur la hifi. La télécommande fonctionne bien aussi +-5 M salon. EDIT branché sur mes Kef biblio très bon son pour moi écouté sur plusieurs genre de musique , pièce de 20M², écoute principale Qobuz et vinyles, Mélomane mais pas audiophile.

It offers excellent connectivity options, and the built-in DAC is a fantastic bonus, supporting high-res audio even over Bluetooth. It does get a little warm after continuous use for an hour. Its compact size makes it a perfect fit on my desktop table. I'm using it to drive my old Sony bookshelf speakers along with a T5 active subwoofer. The sound quality is outstanding with good stereo separation and imaging. It's truly value for money.

Arrivato perfettamente imballato e sigillato,una volta collegato ho notato un suono un po' aspro, caratteristica che è quasi scomparsa dopo svariate ore di utilizzo,piuttosto sensibile ai cavi sia di linea che di potenza,dopo il rodaggio il suono tende verso tinte chiare soprattutto a volumi più elevati , sostituendo i cavi di potenza placcati in argento con dei cavi in rame ofc il suono è cambiato acquistando maggior calore e naturalezza,la potenza è sufficiente per sonorizzare ambienti anche di 20/25mq, silenzioso,nessun rumore di fondo o di commutazione del segnale,dispone di un display OLED di colore verde piuttosto piccolo che indica sorgente,volume e frequenza di campionamento dato che al suo interno è presente un dac PCM/DSD,rispetto al collegamento analogico l' uso del dac produce un suono più cristallino con un basso molto controllato anche se preferisco l'entrata analogica che dona maggiore corposità e naturalezza,per il prezzo direi un ottimo apparecchio.Consigliato.

Le Aiyima D03 est un ampli numérique fort compact, dernière itération des amplis de Aiyima. C'est un ampli très compact, doté d'un interrupteur d'allumage en façade, d'un bouton pour changer les sources et d'un potard de volume. Le potard est egalement un bouton permettant de changer basses et aigues à la volée. En façade arrière, l'amplificateur présente une prises USB B un port d'antenne bluetooth, une entrée coaxiale numérique, une entrée coaxiale analogique ainsi qu'une sortie subwoofer. Les connecteurs de cable d'enceintes acceptent les fiches bananes, ce qui est vivement conseillé. L'ampli est alimenté par un transformateur délivrant 32 volts. Une télécommande est fournie, celle-ci présente une bonne portée. L'amplificateur est détectée automatiquement sous windows 10, aucun driver n'est nécessaire. Le son est bon plutôt rond, riche en basse même lorsque les basses sont réglés sur 0. Le son est très différent du modèle A07 de Aiyima, moins chirurgical, plus enveloppant, ce que personnellement j'apprécie beaucoup pour écouter rock ou electro. Pour faire simple, à réception, le D03 a immédiatement remplacé le A07. Un très bon ampli que je conseille pour un prix très contenu.
