I bought the A07 Pro to create a second system in my house. I use it in my home office. I am someone who has built and enjoyed lots of stereo systems over the years including some fairly audiophile set-ups. My musical tastes are quite wide ranging - classical, pop, jazz and some dance music. I have used it as a desk-top amp and also integrated it into a medium-sized room. I have tried the A07 Pro with Mission 760iSE speakers, Kef HTS2001 speakers, Cambridge Audio Mini12’s and with a Cambridge Audio MinX301 Subwoofer. For inputs I have used Bluetooth and RCA from an outboard DAC using digital sources including basic streaming, HD streaming and FLAC. The A07 Pro is a bright and responsive amplifier with plenty of power and headroom. The sound is transparent and detailed with very little distortion at normal listening levels. It handles most musical material with ease - vocals are clear and crisp, mids are well controlled and the bass is tight and rhythmic. I have listened for long periods and love it. It is very musical and easy to live with. This is an excellent value product - the performance at this price point is exceptionally good. The A07 Pro has a very useful Aux Out so you can add a Subwoofer if you like. The tone controls work well if you need to adapt the sound for your room. The A07 Pro has excellent built quality - the switches click nicely, the rotary controls are smooth and the case is solid. At the back the terminals and speaker bindings are a good quality - I use banana plugs for mine, they work perfectly. The A07 Pro doesn’t run hot or have any issues like that. The connection to the on-board Bluetooth is quick and easy and works perfectly. You can get it out of the box, wire up some speakers and connect a phone with bluetooth and have great quality music playing in just a few minutes - it could not be easier if you just want a basic setup like that. Aiyima is a good company to deal with - they have good customer service and take pride in the products that they make.

Sending rear audio wirelessly from a front AV 5.1 amp to rear standard speakers should be an off the shelf package. You need a wireless transmitter + receiver to get rid of all those wires. I had such a package with my RocketFish TX+RX, but the amp receiver died after 5+ years of good service. This AIYIMA A07PRO (Bluetooth 5.2) was but half of the solution - I still needed a compatible transmitter. I took a gamble on the "1Mii Bluetooth 5.2 Transmitter for TV to Headphones" (£39.99). It works! The two Bluetooth devices pair up just fine, and as both are BT v5.2 they speak the same lingo and support the same audio codecs (eg aptX Low Latency). I *assume* any Bluetooth device which can "cast audio" can be received by the AIYIMA amp, which is just "headphones in disguise". Wireless headphones are just a mini-amp + mini speakers. The AIYIMA has a beefier amp and you plug in your own speakers. Simple, although it was not obvious to me at first. The AIYIMA amp wont go 300W without a 48v power supply, but I dont want 300W blasting out for rear surround sound. It fills in the rear audio more than enough as it is. I played some Dune Part 2 (4K) through my set up; front Denon 7.1 AV amp, front B&W stereo speakers (wired), front B&W centre speaker (wired). The rear/surround speaker terminals go into a "speaker level to line level converter" I found online. This converts loud speaker voltage to quiet voltage and outputs a 3.5mm stereo plug. This stereo plug goes into the 1Mii Bluetooth 5.2 Transmitter. The transmitter sends the audio wirelessly to the A07PRO, which amplifies the signal and sends it to my regular wired Tangent bookshelf speakers. My rear sub is also done wirelessly using a couple of tiny Marmitek boxes. These are stereo but I only use one channel. The audio from the AIYIMA is more than good enough for surround sound. Having volume + tone controls lets me balance things to my personal taste. The sound is clear and punchy and I detected no noise. I turned my front amp up to 100 (with nothing playing) and I had to put my ear right up against a rear speaker to hear the faintest hiss. At 50 there was no hiss. 50 is pretty loud - I generally listen around 30 during the evenings. I detected no lag between front (wired) and rear (wireless). My lounge is quite small so distances are short. My Denon amp allows me to set individual speaker "distance", which could allow me to fiddle with "lag", but I feel no need. The A07PRO has a metal case and feels quality. Metal will help evaporate away heat, which in turn helps the electronics live longer. My AIYIMA is on the floor next to my sofa. I can reach down, twiddle the knobs, all without leaving the comfort of my home cinema seating. I might treat it to a mini table. My now defunct RocketFish would output mains hum to the rear speakers when there was no signal (ie front amp turned off but front transmitter left turned on). The A07PRO does the same with the new 1Mii transmitter. Its a problem with my local earth levels/grounding. If I turn off the transmitter the mains hum stops. Just thought I'd mention it in case you noticed similar - for years I thought it a problem with the RocketFish, but turns out its my jumble of power supplies behind the TV. I'm very pleased with this device, and the fact it paired so easily with another device from a different brand. I'm sure other Bluetooth transmitters will work fine with the A07PRO, but having BT 5.2 both ends seems to be a happy marriage.

I love this amplifier! I made myself a small stereo for my desk using some Cambridge Minx speakers and an Aiyima A07Pro. The sound is great and I can listen to it all day. I listen to a wide range of music and everything sounds just perfect. Treble is transparent without any harshness, mid-range is clear especially for vocals and the bass is tight without any distortion even through small speakers. I have tried with other bookcase speakers and everything works just fine - the A07Pro has plenty of power for most situations and is absolutely great in small rooms or for my desktop. The A07Pro is really well made, the case is solid and the rotary controls are smooth and high quality. The amplifier is super easy to use using built-in Bluetooth connectivity - you can just stream music from your phone using Spotify, Youtube Music, Apple music or any other service. The bluetooth connection is perfectly stable with no drop-outs at all. The A07Pro is easy to connect to any speakers too. If you have a sub-bass speaker this is also easy to connect using the AUX out on the back of the amp - very handy feature. It feels like a quality product and is a great price.

Great little ClassD amp. Appearance and feel suggests its well made. Clear and fast sounding. Very neutral sound with no colouration. Tone controls boost/ cut nicely judged. Limited physical connectivity but Bluetooth works well. Goes very loud. Very happy with this, especially good value.

I needed a small, affordable amp for occasional use at birthday parties and other events. I read several reviews on Amazon and this one had very good ratings. I'm not disappointed with my purchase! I have a decent set of speakers and this amp powers them easily. The sound quality is very good, and the tone and bass controls are useful. I mostly use the amp via Bluetooth from my phone, but the only downside is that the phone needs to be paired each time. Overall, I would definitely recommend this amp to anyone looking for a small, budget-friendly option.

This little amp has a big heart. Bass notes are distinct and treble is clear and not harsh. An all round bargain. Let it run for a few hours before listening intently and the clarity builds over time. Cannot fault it, and I normally listen to excellent British hifi costing more than ten times the price. This little unit may be my best purchase of the decade.

Sound cut out on Bluetooth input when amp ecountered music with some heavier bass. The amp was only outputting an estimated 5 watts, it was worse when volume was increased. Nice little unit, could just be poor testing/quality control. Returned for refund.

I have a pair of lovely speakers that have been sat unused for 5 years because the amp wouldn't fit where I wanted to set it up. I've just bought one of these and it's absolutely brilliant and so small. Perfect solution for my problem and I highly recommend. Get one!

Good piece of kit 👍 the Bluetooth seems good no cutting out so far , I question how they measure the output watts but the sound is quite clean so I like that the best👍

Lo que no me gustó es la construcción del equipo, al menos el mío viene completamente torcida la caja, lo cual hace que no calce bien y se sostenga sobre tres patitas en lugar de las 4 (adjunto video). Lo compré para rescatar unos altavoces de estéreo viejos y los levanta bastante bien; Pioneer de 100W a 6ohms c/u, no paso de la mitad del volumen y suena con fuerza sin calentarse ni distorsionarse, para la sala donde las tengo es perfecto el sonido. El bluetooth tiene buen alcance y conexion, solo hay que alejarlo del módem pues puede interferir. Las perillas y switches se sienten de buena calidad, giran suavemente y enciende y apaga con protección, por lo que no hay un choque de sonido y no hay daño a tus altavoces, pero aún así siempre hay que bajar el volumen antes de apagarlo. Los eq treble y bass son un plus, no lo he probado con subwoofer; pero en mis bocinas se escucha bastante ponchado el bajo.

Goede sound aan een betaalbare prijs. Enkel de bass en treble regeling zijn moeilijk te interpreteren van instelling. Best is een zo goed mogelijke bron te gebruiken voor de best mogelijke kwaliteit. De Bluetooth is een goede aanwinst, maar je hebt er een niet voldoende geluidskwaliteit mee. Gevoed met raspberrypi een degelijke DAC met volumnio op maken een wereld van verschil voor het afspelen op deze versterker. Eén 48 volt adapter is geen overbodige luxe als je stevige luidsprekers wilt aansturen. Warmte ontwikkeling is rond de 45 graden na een tijd van stevig gebruik. Ik had deze uitvoering liever gezien met enkel een versterker en volumeregeling met afstandsbediening, eventueel aangevuld met toonregeling die je kan overbruggen en enkele inputs meer, met selectie via afstandsbediening.

必要十分な機能と性能がコンパクトに詰まっている、そんな印象のアンプです。 10年ほどリビング使用でエージングを通り越しているDali Zensor1を鳴らしてみました。 Bluetoothにて、エクスペリア1からaptX HDで接続した感想です。 このアンプにはラウドネス機能などないのでバスとトレブルを少しだけ盛ってやるとちょうど良く鳴ります。 まあ素直な音というか、何の着色もない「ただ増幅ししてるだけー」という音が出てきます。 悪く言えば味気ない、良く言えばスピーカーの音だけを素直に楽しめる、そんな感じ。 自作スピーカー鳴らすのにベストな相棒な気がしますね。 Zonsor1程度のスピーカーですとウーファーのダンピング不足は感じません。 高BLの大口径ユニットをドライブしたらどうなるかは正直わかりませんが、小型ブックシェルフならこれで十分ではないでしょうか。 オペアンプも交換できるようですので、音に色を足したければ個人の好みに追求できそうです。 無信号時のノイズも全く気になりません。 「こういうのでいいんだよ」 そんなセリフを言いたくなるアンプです。 強いて言うなら、48V対応なので48VのACアダプタ付属すればいいのに…と思いました。 追求したくなる人には無駄な出費になりますしね。 アンプ電源部のデカップリングコンデンサがかなり小さいです。 ここを10000μF程度に替えてあげると低域が良くなりそうです。 いろいろ改造する楽しみもありますね、オタク心を刺激してくれるヤツです。 オペアンプ交換可能 素直な音 トーンコントロール量も十分 そしてなによりプチティシュ箱より小さい大きさが良い 星4.5デスッ！

Le Aiyima A07 pro est un amplificateur numérique ultra compact (11,4 cm * 3,2 cm en façade) alimenté par un transformateur séparé. L’alimentation 36V-6A avec prise 230 V européenne est fournie. Elle est de taille importante, mais peu facilement être dissimulée du fait d’une bonne longueur de cordon. Le carton contient aussi une notice recto-verso Il propose une entrée RCA à l’arrière ainsi qu’une sortie jack 3,5 pour un subwoofer actif. Il est compatible bluetooth 5.2 Les 4 borniers d’enceintes sont situés eux aussi à l’arrière de l’appareil. Pour le câblage des enceintes, je recommande l’utilisation de fiches bananes bien pratiques. Les boutons de façade permettent l’allumage/extinction, le changement de mode RCA/bluetooth, le réglage des basses et des aigus, ainsi que le réglage du volume. C’est très simple et efficace pour une utilisation quotidienne. Avec le transformateur fourni et mes enceintes sous 8 ohms, la puissance est de 2*100W. On peut monter jusqu’à 2*300W en remplaçant l’alimentation (pas testé dans mon cas, l’amplification étant largement suffisante avec le transformateur fourni). A l’usage, en mode RCA comme en mode bluetooth, l’amplification est très dynamique. La puissance maximale et très confortable et puissante. Les réglages des basses et des aigus sont très efficaces et modifient significativement la restitution sonore. J’ai laissé les aigus sur la position centrale et j’ai un peu renforcé les basses pour compenser l’absence de caisson dans mon cas. En bluetooth, il est reconnu comme A07 pro dans le gestionnaire bluetooth android. L’appairage est immédiat. A mon avis, le rapport qualité prix de cet ampli A07 pro est excellent. Etant donné la puissance de sortie, largement suffisante pour sonoriser une pièce de 20 à 30 m² sans distorsion ni souffle. Et sa compacité est un réel atout. L’ajout du bluetooth est une belle évolution par rapport au A07 standard.
