AIYIMA A07 MAX HIFI Power Amplifier 2-Channel Home Audio TPA3255 Class D 300W x2, Bridged Mono 600W, 3.5mm Line Output, Integrated Desktop Digital Amplifier With 36V Power Adapter

I was delivered with the 36V 6A power adaptor which was of good quality and I was impressed by it's performance and power output.It's very small and I use it to drive two 8ohm loudspeakers. I couldn't turn the knob past 3 o'clock level it just gets too loud even for 8 ohm speakers at half the power resisted.Sound quality is Clean and the responsiveness to EQ is also good.I couldn't get the deep bass from the stereo speakers , probably the tpa3255 chip redirects the mid-low bass to the 3.5mm sub out.The upper bass, the mid , the treble are all clear and smooth too.Also there is no thumping sound or any kind of noise /static noise when mute or pause, only the sound of the media comes out the speaker.Overall the product has high value in terms of price.

I am in the process of breaking in. I felt this amp has sufficient juice with the 36v power brick supplied with the amp, however a 48v power supply option would helped customers extract more output from this amp. Out of the box the amp sounds great with the stock op-amps. I will have an op-amp rolling done to test the performance further. One notable inclusion are the speaker Banana Sockets they are strong and audio grade when compared to other amps with in similar price range. The only flaw I could find is the shape. Its more towards the side than going back, this can create some problems if you want to place a DAC on top of the amp unless Aiyima decides to launch a suitable DAC to compliment this amplifier. Over all a good amplifier for those who likes to listen to music with out tone controls. Muse or Sparko discrete Op amp rolling could be experimented to enhance the sound quality to the next level. Bare in mind these upgrades are not cheap

The amplifier is quite cheap for the power output it claims and it can't supply 600W or 300+300W at full power with the recommended power supply and speaker conditions.The manufacturer provides 36V charger but the amplifier works at its best on 48V.Yes it's a good, compact and budget friendly amplifier, it has very low noise level and good sound quality. It does heat up when working near it's maximum capabilities so it is suggested to keep a fan blowing sir over it when it's running. It is good for small functions and minimum DJ parties.It can supply (mono mode) measured by me.8Ω, 36V - 110W8Ω, 48V - 160W4Ω, 36V - 150W4Ω, 48V - 240W

AMAZING AMPLIFIER, great sound quality, but as class D, a little bit of dryness in sound.

Does a good job of breathing new life into your old hi-fi system speakers, build quality is top notch, most importantly this model gives you upgrade option since it's a mono, you can buy another one and run them together for bigger speakers/sub. I'd recommend this

Don't get what I expectedI have a 200 watt class AB amplifier it is far more loud and punchy this 600 watt class D amplifier is as good as my 200 watt class AB amplifier

Very Good amp, Nice sound .

The home D-class amp is compact,powerfull 2,0 with Sub out facilitySadly doesn't support Bluetooth connect,had to connect to VCD,no USB,are theConsPros are compactness,good power stereo D class amp,ideal for home,parties etcHighly recommended

Qué se puede decir de este Aiyima A07 que no se haya dicho ya en tantos videos que se han publicado? Sonido excelente, precio justo; no se calienta, no mete ruido; viene con una fuente de poder de 36 volts (los modelos parecidos de la misma marca y de la competencia como Fosi Audio y Douk Audio traen la fuente de 32 volts) ¿Eso importa? pues según los datos que publican las tres marcas mencionadas, el cambio de fuente de poder implica un aumento promedio de 25 a 30 whats, y si tomamos en cuenta que la fuente poder de 48 volts que vende Douk Audio por separado cuestas más de 80 dólares; pues el A07 tiene una pequeña ventaja sobre la competencia.

Le Aiyima A07 MAX est le dernier né des amplis à base de puce TPA3255 qui sont dernièrement très à la mode en raison de leur rapport puissance prix très favorable.Le A07 MAX est simple mais bien conçu, il dispose de gros borniers permettant de passer du câble d’enceinte de bon diamètre ou alors encore plus pratique, des fiches bananes.Il ne dispose que d’une entrée RCA simple, il vous faudra donc idéalement ajouter un DAC pour le brancher directement sur votre ordinateur et ainsi bénéficier de ses grandes qualités.L’installation est très simple, il est doté d’un bloc d’alimentation de 36 volts.Il peut également être équipé de blocs plus costauds jusqu’à 48 volts pour une puissance supplémentaire au prix d’un dégagement de chaleur plus élevé.L’ampli est à ce niveau bien conçu car équipé de petits trous permettant une meilleure dissipation de la chaleur. En utilisation et avec l’alimentation de 36 volts, l’amplificateur reste tiède.Il dispose également d’une line-out en mini-jack pour y relier un caisson de grave actif.L’allumage de l’ampli se fait par rotation d’un gros potentiomètre en façade, rien de plus simple.Détail intéressant pour les plus techniciens d’entre nous les op-amps sont remplaçables selon le désir de l’utilisateur, un détail sympathique pour les puristes.En l’état le son qui sort de cet amplificateur est remarquable, avec un rendu des percussions que je n’avais jusque-là jamais entendu sur aucun amplificateur chinois, les impacts sont époustouflants et transfigurent les enregistrements.La puissance développée par l’amplificateur est suffisante pour la plupart des enceintes et impressionnante par rapport à la taille minuscule de l’appareil.Un très bon appareil.

Potenza, dettaglio, profondità. Un campione di qualità/prezzo!!

É razoável em termos de áudio isto é, não é ruim, mas não tem pressão sonora que possa empurrar caixas um pouquinho mais exigentes, como, por exemplo, as Polk Signature ES 20. Não entendo como alguém pode dizer que o áudio desta amplificador posso agradar audiófilos. Não sou chato que procura ouvir o sussurar das formigas e nem zumbido de anjos em nenhuma melodia ,mas definitivamente este equipamento carece de impacto para reproduzir música em alta fidelidade. Já começa tudo errado, pois o botão do potenciômetro não gera audio audível até 1/4 de sua revolução.

Use them with Wharfdale Diamond 12.3i and some old Wharfdale Denon 2 speakers no problems.I've nothing really to compare it with but it works and there is no hum and the volume control is lovely and smooth with no crackle.There is a delay from input to output , which means that if you want to use an active sub woofer you'll need to take it's input from the aux out of this amplifier as that is also delayed.Talking about delays, when you turn it on, nothing happens for a second or two which surprised me but does not upset me.
