- A07 Pro TPA3255 Stereo Amplifier Bluetooth 5.2 300Wx2 HiFi Class D Amp 2.0/2.1 Channel Audio Power Amp for Home Audio Speaker with Bass Treble knobs& 3.5mm Line Output,Supports 24-48V

As a happy owner of the A07 I was interested in getting the A07 Pro for my family. So far I’m quite pleased with the performance of the A07 Pro. It still sounds excellent like its predecessor but with bluetooth and tone controls, I find it more convenient to use than ever. In my listening tests, I found it presents a very full sound, with clear separation, and relatively wide soundstage for the size. Imaging performance was decent too, particularly with some tracks like The Adults Are Talking by The Strokes you can clearly hear the direction of the instruments and vocals. I find the A07 Pro and the A07 to be quite similar acoustically, though I found the A07 Pro’s treble seems a smidge more pronounced. However, overall they are very close and the tone controls on the Pro mean you could easily adjust the sound to your liking. Regarding the Bluetooth, I’m happy to say it is as impressive as the RCA input, to the point where if you didn’t tell me it was Bluetooth I probably would never have guessed. I tested it with my iPhone 12, and at a decently high input volume, this thing rocks (and with decent speakers it obviously beats the pants off of any portable bluetooth speaker). The only potential con you should be aware of is that it doesn’t support the LDAC codec, but it doesn’t matter to me personally and to my ears the Bluetooth already sounds great. One nitpick I have is that I do wish it had a tone control bypass switch. It would make it easier to switch between using the A07 Pro’s tone controls vs an equalizer, and some people just don’t prefer tone controls whether for latency concerns or other possible reasons. Overall though, the A07 Pro is a great little amp. I think Bluetooth makes it very easy to use especially for usage with a laptop or phone, and tone controls are handy to have. It's also worth noting this one comes with a slightly beefier power supply compared to the A07 (36V 6A vs 32V 5A). For the sound quality and added convenience, the A07 Pro is a pretty nice value option and I would definitely recommend it to people who are looking for a great sounding amp, especially for those who want to use it with portable devices. I would particularly recommend it to audio enthusiasts who might be looking to get something high quality for their family who would appreciate the convenience of Bluetooth.

I recently acquired the Aiyima Pro A07 amp to power my bookshelf TV fire stick and echo dot configuration, and I must say, it has taken my audio experience to a whole new level. This small but mighty amplifier has exceeded my expectations and proved to be the perfect match for my speakers, not only in price but in performance. The Aiyima Pro A07 amp effortlessly complements my Polk ES15 speakers, unlocking their true potential and delivering an immersive soundstage. Whether I'm indulging in my favorite music playlist or enjoying movies and TV shows through my Fire TV Stick, the combination of the Aiyima amp and Polk speakers creates a sonic experience that is simply breathtaking. One of the standout features of the Aiyima Pro A07 amp is its versatility in connectivity. It seamlessly integrates with my Amazon Echo Dot, serving as the backbone of my smart bookshelf audio setup. With the ability to connect multiple devices via a line-in or via Bluetooth, I can easily switch between sources and enjoy a seamless transition in the audio output. The amp's compatibility with the Fire TV Stick using it in the Alexa "home theater" setup ensures that I get the most out of my YouTube and Amazon Prime Video sessions with crisp and clear sound. The build quality of the Aiyima Pro A07 amp is exceptional, boasting solid construction that exudes durability. Its sleek and compact design makes it a perfect fit for my bookshelf setup, while the user-friendly controls, which include treble and bass controls, are easy to use and feel solid in my hands. Overall, the Aiyima Pro A07 amp has exceeded my expectations and brought my audio setup exactly where I wanted it to be. Its seamless integration with my speakers, Amazon Echo Dot, and Fire TV Stick has enhanced my listening and viewing experiences with easy voice controls for music playlists and video. If you're seeking an amplifier that delivers exceptional performance and versatility that fits in a smaller space, and fits within your budget, but has sound and power that goes well beyond what you would expect for that price, look no further than the Aiyima Pro A07. It's a great little amp!

This is my review for the AIYIMA A07 Pro. I have had this amplifier for a few weeks now and I am loving it. It is a class D stereo amplifier so in terms of its power delivery capabilities, it is absolutely amazing. It provides a very transparent and large sound stage where you can clearly and distinctly hear the clarity and focus of instruments. I absolutely love the bass and treble controls as it allows me to dial in the sound signature of my Jamo S801s and S803s just right. The Jamos have a bit of v-shaped response so the ability to dial the sound to my liking without needing an EQ app is great. I am pairing the A07 Pro with Fiio K3 DAC and it delivers really nice results; the sound is crisp, the vocals are bright, and the bass is punchy. I don't have a subwoofer so I am not using the line-out so can't comment on that. If you are looking to have your desktop passive speakers powered with a small-footprint amp that doesn't heat up and delivers up to 300 Watts per channel (overkill in my opinion), this will get the job done and more. One thing to note is that unlike the A08 Pro, the A07 does not support the Sony proprietary LDAC codec however I think the lower cost makes up for it. I also wish the tone controls were detented like the A08 Pro so it is easier to adjust the levels of both bas and treble. If you like tinkering with the inner hardware, you can also upgrade the op-amps (5 of them). It is fairly easy to get inside and swap the op-amps if you know what you are doing; watch a few videos if you need to before you try. This in my opinion is an excellent choice for anyone getting into HiFi music listening.

I bought this because I have a A07 and wanted one with Bluetooth for my in-wall JBL speakers. I'd been running a 20w x2 with Bluetooth 2.1 setup but it wasn't enough for the speakers and the Bluetooth always had interference. So I upgraded to this and have my Echo (gen 4) connected to it. I figured with the extra (awesome) power and upgrading the Bluetooth, it'd help a lot. In terms of audio quality/power, its a giant step up. The speakers rock and really came alive with this. But the Bluetooth still has interference. I'm trying different channels on my home router as that can cause interference but it still crackly at times. I have a remote switch for it so I can reboot it. Once rebooted,it'll be clear for a day or two and then the interference comes back. A bit frustrating. The amp still sounds amazing and has great controls. Really love that. Worst case, I figure out a way to hardwire in the Echo for better quality. I was just hoping the Bluetooth would do fine.

For video context, my workplace sounds like a plane engine going on all the times and need hearing protection and most bluetooth speakers like jbl boomboxes get completely drowned out. This little amp driving with some 88db sensitivity speakers(which is quite low, sensitivity rating determines speaker loudness, wattage ratings dont matter) keeps up quite a bit as you can see in the video a 400 dollar jbl boombox would not even be audible in a video. Used the line out with a male 3.5mm aux to dual male rca connector to hooked it up to a Klipsch r-sw12 subwoofer. Works flawlessly. 3 ohm performance - I connected two pairs of dayton b652 which are 6 ohms each wired in parallel which gives 3 ohms final impedance. If you have the bass up to half way while volume is 100%, the amp will overheat and start cutting off. If you use bass or treble adjustments you'll need to get your max volume down to 60% or lower, whatever it takes to keep the amp running slightly warm and not hot. You can push the amp harder if you have a dedicated cooling solution like some fans or surrounding heat sink. This is of course pushing the amp far beyond the manufacturer rated limits of 4 ohms. I would definitely not push 2 ohms on this amp, it'll just overheat before it can get loud or play long enough. At least the amplifier has good protection circuitry to cut off before severe damage happens. Yes I've tortured tested this amp to a large extent and it survived with flying colors. With 8 ohms, 6 ohms or 4 ohms speakers the amp doesnt struggle at all. Also the bluetooth connection is very stable, on my s20 phone it auto connects to aptX and it sounds massively better than my coworkers iphone 13. The iphone 13 maxed out was missing like 2 clicks of volume slider in comparison to the samsung and lacking severe detail in midrange and treble like several wet towels were thrown on my speakers. Sucks to not have aptx and Ldac which is why I havent jumped ship from android yet. Bluetooth range is quite nuts. Farther than my best bluetooth headphones/earbuds. I got up to around 40 meters before it had issues and it was still playing and connected through walls as well.

I chose this amp for its power, a healthy step up from the others in this niche, the Bluetooth capability, and the bass and treble controls. It is now the muscle behind my Workshop Stereo. I like that it has no cooling vents on the top surface to trap shop dust, too. It's powering my Dynaco A25 speakers, from Denmark, made in about 1964! They are famous for their rich open sound, flat response across frequencies, and beautiful cabinet and grille cloth. Classics from 62 years ago! My dad bought 4 of them for his HiFi system in our family home in the Hollywood Hills. Classics that I’ve held since 1975! Now they sound absolutely fantastic powered by the clean and punchy amp, contoured perfectly with embassy and treble controls and the adjustable crossover at the back of both speakers. They are 8-ohm speakers and absolutely BLAST clean sound when pushed. The Bluetooth receiver allows me to stream podcasts, NPR, Spotify etc. if I am not using my Pioneer 100 Disk CD Changer! (A Craigslist score, that came with over 500 disks!!!) get this tiny amp. It ROCKS!

My intended use for this amp was for rear home theater speakers in a 5.1 configuration, taking advantage of the aptX low latency feature. The styling is very clean and inobtrusive. The blue LED emits a faint glow to let you know it's on and connected to AUX or bluetooth status. The build, knobs, and switches are all very solid. I tested it on ELAC UB5's a very demanding low sensitivity 4 ohm speaker and found it up to the challenge and able to play at louder volumes w/o distortion than my 100W Fosi mini-AMP with perhaps a little more oomph on the bass. The sound is clear and crisp with no audible noise or hiss, even while adjusting volume and tone. The included 36V x 6A beefy power supply brick, at most capable of outputting (P=V*A=216W) = 2 x 108W, was never more than mildly warm, even when playing music at loud levels for extended periods. Similarly for the amp itself, mildly warm but never hot. I'll probably keep it on most all of the time. Wattage measurements using KILL A WATT showed idle power of 8W and high volume, higher than most people would ever listen to, of only 10W. I can't imagine how loud you would have to play it to hit 50W sustained and above. I personally can see no reason to bother to connect this to a larger power supply. I had no trouble pairing it with a Samsung Galaxy S9+, 1Mii transmitter, and Trond transmitter and was able to confirm aptX & aptX HD support. It immediately connected to the last paired device when turned on. There were never any noticeable clicks, pops or dropouts with the transmitter around 15 feet away. To pair with another device, I power cycled and unplugged it and then went through pairing again. I also tested the AUXIN port streaming music from Spotify to a Google Chromecast Audio port and it also sounded great. I could not differentiate the quality between it at bluetooth aptX HD. Some missing features that may be important depending on application include: - simultaneous pairing with multiple devices - headphone jack and/or USB connector - esp. for gamers - indication and/or control of aptX, aptX HD, aptX LL, SBC - remote control - esp. if not in a convenient location These mini-Amps are great for applications like home theater (both front and rear speakers), bookshelf speakers in the living room or kitchen, in a dorm or apartment, or desktop computer speakers. Paired with a modest subwoofer, it's all of the audio that most people will ever need in a nice small package. Disclosure: I received this product for free in exchange for writing a thorough review. That said, I have no hesitation giving this product 5 stars and recommending it for the above applications and many others.

I've tried it with both my 2.0 systems and was very pleased. I noticed no difference in sound quality compared to my Yamaha receiver. The Yamaha has much better EQ, but I got close enough with the Aiyima's knobs. My big problem is the Bluetooth. It worked fine for about a week, but now it's broken. If my phone is next to it, BT works fine, but if I'm standing next to it and holding my phone the signal is trashed. I tested it against a standalone BT receiver to confirm the results. Edit: Yima customer service reached out to me after seeing my review. They've been denying that the Bluetooth is malfunctioning despite video clearly showing the switch set the Bluetooth, the antenna installed, and audio cutting out. They asked for the video, and now they don't seem to be able to understand what they're seeing and hearing. I have added it to this review.

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.

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.

Bisogna sempre confrontare le prestazioni con il prezzo pagato. In questo caso il rapporto qualità/prezzo mi sembra decisamente buono. L' ho collegato alle mie Sonus Faber Concertino le quali, pur non essendo certamente un Top di gamma, hanno una presentazione musicale assolutamente piacevole; il risultato è stato al di sopra delle mie aspettative. Ho altro materiale migliore con il quale confrontarlo, sia a valvole (Balanced Audio Technology) che a Mosfet (Hegel) che pilotano altre Sonus Faber di livello superiore e devo ammettere che questo "cinesino" , sempre che non gli si chieda troppo, restituisce una ottima immagine stereo, una buona dinamica, percussioni credibili e una gamma sonora notevolmente estesa. Il tutto con l' alimentatore di serie fornito; c'è da considerare che esiste uno spazio di miglioramento lavorando su un' alimentatore più capace. In ultima analisi questo esemplare mi ha pienamente soddisfatto.

Mit dem A07 Pro bringt Aiyima den Nachfolger bzw. das erweiterte Modell des beliebten A07 heraus. Im Gegensatz zum minimalistisch ausgestatteten Vorgänger gibt es jetzt zusätzlich noch eine 2-Band Klangreglung und Bluetooth. Ansonsten sind die technischen Daten dem bereits sehr belieben Vorgänger ähnlich. Wer den A07 bereits kennt, weiß, was ihn hier erwartet - viel Klang und Leistung zum kleinen Preis. Zunächst möchte ich auf die beiden Neuerungen des A07 Pro eingehen. Die neu hinzu gekommene Klangreglung ist besonders interessant, wenn man den Verstärker ohne Pre-Amp direkt an einem Endgerät ohne Klangreglung betreiben möchte. Die beiden Regler für Bass und Treble sind Aiyima tyisch aus Metall und funktionieren bestens. Die Regelung ist fein genug für gezielte Eingriffe ins Klangbild und bietet ausreichend Regelweg für die meißten Fälle. Kleinere Raumprobleme, Eigenheiten von Lautsprechern oder auch die Anpassung an den eigenen Geschmack sind damit schnell und gezielt möglich. Dazu passt dann auch die neue Bluetooth Funktion, mit der man den Amp z.B. direkt mit dem Smartphone koppeln kann. Das funktioniert in der Praxis problemlos, die Verbindung ist stabil und die Reichweite sehr gut. Auch vom Nebenzimmer ist bei mir der Empfang jederzeit gut. Die technischen Daten im Einzelnen: Chipsatz: TPA3255+NE5532+QCC304X Bluetooth: 5.2 Bluetooth-Unterstützung: 16-24 Bit 44,1-48 kHz Unterstütztes Format: sbc/aac/aptx-ll/ aptx-hd Chips: Austauschbare Operationsverstärkerchips: SRT3609SM, OPA2604, OPA2134, LM4562, JRC5532, OP275GSZ, OPA1612AIDR usw. Verzerrung: 0,002 % Signal-Rausch-Verhältnis: 90 dB Frequenzgang: Bässe ±12 dB Höhen ±10 dB Eingangsempfindlichkeit: 0,84 vRms Lautsprecherimpedanz: 4-8Ω Ausgangsleistung: 300 W * 2 Eingangsmodus: RCA, Bluetooth Ausgangsmodus: 2.0 Lautsprecher + Aux Arbeitsleistung: 24-48 V Gleichstrom Beim Klang ähnelt der A07 Pro dann erwartungsgemäß sehr dem Standardmodell. Der Klang ist insgesamt sehr offen, weitgehend neutral mit sehr schönen luftigen Höhen und sauberem und druckvollen Bass. Der im Vergleich zum A07 etwas geringere SNR Wert fällt höchstens im direkten 1:1 Vergleich auf und ist in der Praxis vernachlässigbar. Dafür punktet der A07 Pro mit der Klangreglung, die den Verstärker natürlich klanglich flexibler macht. Egal ob Klassik, Jazz oder auch elektronische Musik oder Heavy Metal - der A07 Pro reproduziert alle Stilrichtungen sehr souverän mit reichlich Leistungsreserven. Es gibt deutlich teurere Amps, die dem A07 klanglich nicht das Wasser reichen können. An richtig guten Lautsprechern hat der A07 Pro noch die eine oder andere Überraschung zu bieten. Insbesondere die Mitten machen dann richtig Spaß und klingen nochmal spürbar luftiger als beim bereits sehr guten Vorgänger. Das Sound Staging bei guten Boxen ist ebenfalls erfreulich groß und offen und lässt einen deutlich teureren Verstärker vermuten. Mit dem mitgelieferten 36V Netzteil liefert der A07 Pro zwar nicht die in den technischen Daten angegebene Maximalleistung. Trotzdem ist reichlich Leistung vorhanden, die in der Praxis auch mehr als ausreicht. Jedenfalls beginnen meine Ohren bei wenigen Metern Hörabstand zu den Lautsprechern bereits zu klingeln, wenn der Lautstärkeregler noch reichlich Luft nach oben hat. Dazu bleibt der A07 Pro mit dem 36V Netzteil auch bei höherer Lautstärke noch kühl und zeigt keinerlei Anzeichen von Überhitzung, wie es bei stärkeren Netzteilen der Fall wäre. Auch sonst gibt es am A07 Pro nicht wirklich etwas zu kritisieren. Die Verarbeitung ist Aiyima typisch gut, die Endocer laufen sauber und leichtgängig. Mit dem Stahlgehäuse und dem ordentlich dimensionierten Kühlblock hat der A07 Pro ein Gewicht, das vertrauenerweckend wirkt. Die beiden klassischen Hebel zum Ein-/Ausschalten und zum Wechsel der Klangquelle funktionieren tadellos und lassen das Gerät ebenfalls sehr wertig wirken. Der Aiyima A07 Pro ist ein gut verarbeiteter, sehr gut klingender Class-D Verstärker mit ordentlichem Netzteil und reichlich Leistung für kleines Geld. Was will man mehr? Damit verdient er sich problemlos 5 Sterne. Ich kann das Gerät wärmstens weiterempfehlen.
