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 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

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

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 - 110W 8Ω, 48V - 160W 4Ω, 36V - 150W 4Ω, 48V - 240W

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.

The home D-class amp is compact,powerfull 2,0 with Sub out facility Sadly doesn't support Bluetooth connect,had to connect to VCD,no USB,are theCons Pros are compactness,good power stereo D class amp,ideal for home,parties etc Highly recommended

Very Good amp, Nice sound .

It amplifies.... May be for bookshelf micros, definitely not for power hungry big speakers. I had to plug in fiio dac/amp and h/k avr20 as preamp to get my two 300 watts(each) tower speakers sing, nothing fancy though. Frequency response is not that broad spectrum. Its perfect for 2 tiny speakers in a tiny room. Definitely not for the ears habituated to listen nuanced sounds.

Powerful sound quality very nice

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.

Prodotto perfetto. Ne ho presi due e li uso come finali in mono uno per canale . Suono caldo e dettagliato . Li utilizzo con il loro alimentatore originale .

AIYIMA A07 MAX iMac+Audirvana→TEAC UD-301→AIYIMA A07 MAX→Fostex FF85WK+P800-E これまで本腰を入れて音楽を聴くときは、UD-301にAKG K-501を差すか、STAX SRM-313+SR-L700 MK2を接続して聴いてきました。日常のiMacの音声はBOSE Companion 20で聴いてきましたが、5年使ってちょっと飽きてきました。 そこでCompanion 20の置き換えを考えるようになり、設置スペースの面から、最初はアクティブスピーカーをいくつか物色しましたが、かなり小型のデジタルアンプ（D級アンプ）があることを知り、小型のパッシブ・スピーカーと組み合わせることにしました。 まず、サイズと価格の点から、スピーカーをFF85WK/ P800-Eに決めました。アンプはFOSTEX AP15mk2、AP20dを考えましたが、いわゆる「中華アンプ」もおもしろそうなので、怖いもの見たさもあって、amazonのブラックフライデーセールで１万円を切っていたAIYIMA A07 MAXを選び、2025年11月末にFF85WK/ P800-Eと合わせて購入しました。 2025年12月2日にセッッティングし、鳴らし始めて数日ですが、なかなかよい音で鳴ってくれます。Companion 20よりもはるかに解像度が高く、ダイナミックレンジも広く、定位もよくなりました。低音はCompanion 20の方が出ていましたが、小さな筐体で無理している感じがあり、全体がボヤけていたように思います。 ACアダプターと本体の間にはFX-AUDIO [ACCESSORY SERIES 005] Petit Susieをかましています。これは、Companion 20で使っていたときはほとんど効果が感じられなかったのですが、A07 MAXでは、明確な効果があり、１枚ベールを取ったような、細部までクリアで滑らかな音になりました。 ※Petit Susieは35V以下での使用が推奨されており、A07 MAXのACアダプタの出力は36Vとわずかにオーバーしていますので、使用する場合は自己責任でお願いします。半年使用してみて、発熱などの異常はありません。 ※Petit Susie Solid Stateは「入力電圧25V以下」となっています。

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.
