AIYIMA T9PRO JAN5725 Vacuum Tube Amplifier 100Wx2 TPA3250 Stereo USB DAC Amp QCC3040 Bluetooth aptxHD COAX/OPT HiFi Home Audio Digital Amplifiers with VU Meter(32V power supply)

I recently decided to upgrade my Aiyima T9 amplifier to the newer T9 Pro model, and I must say, the improvements have exceeded my expectations. Not only has the upgraded sound quality impressed me (better quality components, better tube’s and more control over the audio), but the added Bluetooth 5.1 capability and overall build quality have made this a worthy investment. In this review, I'll detail my experiences with the Aiyima T9 Pro and explain why I think it's a an amazing retro style tube amplifier and a fantastic upgrade for anyone considering it. What’s in the Box: Aiyima have provided lots of extras in the box with the amplifier, include a nice USB cable (the T9 Pro has an upgraded DAC - one that is easily the equal of a dedicated DAC of a similar price) and an optical cable (I have being using the T9 Pro with a Wiim Mini Streamer via Optical) and a USB key (with Windows drivers for the DAC - not needed on a Mac). You also get the 2 separate tubes and this should be inserted into the amplifier - it’s actually allot of fun connecting everything. Sound Quality: The sound quality of the T9 Pro is a noticeable step up from its predecessor (and that means an upgrade over most amplifiers at this price point). The Aiyima T9 Pro has noticeable better “harmonic” sound than the T9, I believe this is the mixture of better internal components and provided tubes (see the comparison diagram attached) and the better default tubes provided in the box. I found this lead to a much wider sound stage and better a better separation of individual instruments, which makes listening to my favourite tracks an more immersive experience. Not only comparing the sound to the T9 but comparing the T9 Pro to my much more expensive Denon AmplifIer is a joy (with the same speakers and subwoofer), have given me a newfound appreciation for my music library. Bluetooth Capability: One of the standout features of the T9 Pro is its new Bluetooth capability. The T9 Pro offers a seamless wireless connection, and I haven't experienced any drops or interference while using it. This feature has made it incredibly easy to stream music from my smartphone, tablet, or other Bluetooth-enabled devices. Plus, the T9 Pro supports aptX, ensuring high-quality audio streaming. Build and Features: The overall build quality and the retro look of the T9 Pro is another aspect that has impressed me. The chassis feels sturdy and gives the amplifier a premium feel. The front panel features a sleek and modern design, I love the new digital display that shows the current input source and volume level and the Volume. While the VU meter on the righthand side provides a lovely retro feel to this amplifiler. The control knobs have a smooth and responsive feel, making it easy to adjust the volume and fine-tune the sound to my preferences. The T9 Pro offers multiple input options, including Bluetooth, USB, AUX, coaxial and optical. Moreover, the T9 Pro has a new built-in DAC that is much higher quality that before (I believe the term is transparent with up to 24bit/192Khz), which can significantly improves the sound quality when using super high definition digital sources like USB from a computer. I believe this DAC is close to start of the art for DAC’s so no real reason to get a separate DAC. Some Pros and Cons compared to other ampfliers: Pros: 1. Love the upgraded sound - better internals / more power / better tubes 2. The digital display is fantastic compliment to the VU meter 3. I love the bass and treble controls 4. The remote is great and you can tweak the bass and treble easily with the remote control. 5. Even though it has the same ampflieri chip as the original T9 I believe the better components and the better power supply provided means it plays louder if you want Cons: 1. Compared to similar sounding but more expensive amplifiers it is missing a headphone jack and Phono MM inputs (for turntables with pre-amps) 2. The bluetooth while perfectly fine is not as good as the digital inputs IMO - I would rarely use bluetooth but it is nice to have feature Conclusion: In conclusion, with the Aiyima T9 Pro amplifier I believe almost everything has been improved over the original T9. This is now a viable amplifier alternative to much more expensive €300 or €400 amplifiers. The lovely “warm” sound provided by the tubes added to the better internals has been a fantastic upgrade from my previous T9 model. I wholeheartedly recommend the T9 Pro to anyone looking to upgrade their amplifier or wanting a versatile and high-quality audio solution.

This thing is tiny but I love it. I run two 100W active speakers from a company called Celestion. One thing I would say, it gets quite warm especially if you have the sun shining on it. I t wont be such a problem in Winter but I recommend buying this one: https://www.amazon.co.uk/dp/B0C23XMG9V?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1 The amp is so tiny it sits right on top and the fan will keep it absolutely chilled. Bluetooth is super, I was anxious to use it and thought I'd get digital artefacts but the sound is crystal clear and it connects instantly. It does come with an optical cable, that would have been my next choice if I was unable to use BT. I love the look of these tubes protruding. Sound is amazing. Hope it doesn't break once the warranty expires :/

This is a supremely excellent tiny Chinese amp. There are a good range of inputs, including Bluetooth. It comes with a half decent remote. It fits on my work desktop perfect. It powers some Wharfedale 9.1 speakers effortlessly. It provides a spacious and detailed sound stage, with outstanding clear base response. The best thing about it? There are actually several things.... Firstly, it sits there about a fifth of the size of a regular amp taking up an absolutely tiny space. Its attractive looking; copper rings around a 70s style VU meter and an 80's style led display. There are also valves that light up a nice orange, especially in a darkened room. I honestly don't know what those valves do... but I do know that the unit will work without them, but they don't sound half as good... The big thing? I reckon I've got a decent HiFi system.... that fits on a very limited desktop space! Secondly, beyond the small scale beauty of its looks , its seriously connectable. I've teamed mine with a switching preamp so I can get more RCA inputs. But it also comes with optical, coaxial, USB and BT inputs for your digital sources. Also a nice remote thats more than a credit card sized piece of naffness you often find with stuff from China. Thirdly.... the sound! I remember, in my 20's, taking out a loan to buy my first HiFi rig. Memorable! I went to a local store, listened in their listening rooms, considered and deliberated, and finally invested. I think if I was to evaluate and reflect back in time from my first act of commitment to audio, then amps basically are about as good as they always were . Sources (CD, Phono, computer etc) haven't really changed, especially in the digital age, and are about the same in terms of accurate reproduction. (Many talk about warmth, created by valves, created by phono..... I don't subscribe... digital is fine..). BUT...speakers are vastly, VASTLY improved. Nowadays I don't need to take out a loan to buy HiFi. Nowadays I've realised that being an audiophile is not a technical thing; its about finding YOUR music and enjoying it on a system YOU enjoy, That's all there is to it! Don't spend thousands! Don't feel you need to! This little beast will help you out. It looks great, it sounds great. It will connect to whatever you need it to. It will not let you down in terms of quality. It comes with a big 32 volt power supply. You will not believe the power this delivers from that power supply if that is your thing. At lower levels it is as clear, accurate, warm and harmonious, like the sky on a beautiful spring day...

This product has both excellent sound quality and total versatility. It can be used with an analog line in from a cd player or analog phono stage or it can accept a digital input from a cd players co-ax out or optical out or you can plug in a small digital audio player via its usb. The T9 pro uses its internal ESS 9018 Dac to convert all of these digital inputs to analog and then outputs this via its poweramp to the speakers. There seems to be a synergy between the input valve stage and the output class D Poweramp which sounds so luscious but at the same time detailed and involving. The inclusion of tone controls for bass and treble allows for easy adjustment in tonality but does not detract from the sound quality in any way. It sounds great with the tone controls both set at zero. Overall the sound is big and very 3 dimensional. This has to be the best bargain in HI-Fi for £178. An excellent product and highly recommended.

Powerful for its size 100w per channel, well made. Music a clear and crisp with plenty of punch. A joy to use.

WOW. So glad I went for the Aiyima T9PRO. I had been torn between the Fosi Audio MC331 or the Douk Audio ST-01 PRO. I spent over a week watching YouTube reviews and finally decided to get the Aiyima T9PRO and I’m very impressed so far. I have a humble set up consisting of a Audio Technica LP3 turntable, a Fosi Audio Box22 Phono pre amp, and a pair of Wharfedale Diamond 9.1 speakers. The sound levels are great and the Bass and Treble controls work fantastic. So far I’ve used the RCA and Bluetooth inputs and both work fine. I had read reviews about the VU meter not responding at low volume levels on the Fosi Audio amp which is one of the things that swung me toward the Aiyima amp but I haven’t had this problem and there is a VU meter sensitivity adjustment screw on the underside of the amp. The remote control is great too giving you full operation over volume, bass, treble, audio input selection and power on and off.

Pretty bad.. NOT A 200W AMPLIFIER. Not loud at all. Only have Bluetooth working (which is lucky) none of the other inputs seem to work. Instructions are sparse and difficult to follow.. For the money, IT'S NOT WORTH IT!

I've been shopping around for a while for a small but functional amp, as an upgrade to my workplace system. I'm not an audiophile but am a musician, so good sound quality is really important to me. The original T9 caught my eye and I decided to bite the bullet with the newer T9 Pro model. I've got this paired with some Monitor Audio 50 speakers, and have to say the sound quality is absolutely first class for such a tiny amp! The bluetooth works flawlessly and I've also tested direct input via Windows 11 and Tidal masters, with brilliant results. Just remember to change your audio settings in the Windows control panel to get the maximum bit rate, which will be displayed on the amp. It even comes with optical and USB cables, and the Windows driver on a free 8GB memory stick! It's tempting to look at second-hand amps when starting out in the world of "real" hifi but I wouldn't bother. Just get one of these and you won't look back.

Amplification convenable. A moyen régime, beau son. Belle présentation. Originale. Bonne Hifi

Der Aiyima T9 Pro ist der Nachfolger des beliebten T9. Was der neue All-In-One Class-D Amp von Aiyima kann und ob der Aufpreis zum erfolgreichen Vorgänger gerechtfertigt ist, möchte ich in diesem Review etwas näher beleuchten. Nachdem an meinem TV die Soundbar nicht mehr funktionierte (mal wieder wegen einer ausgefallenen Billig-Fernbedienung Made in China), musste Ersatz her. Da eine vernünftige Soundbar schnell einige hundert Euro kostet und selbst dann klanglich nur ein Kompromiss ist, habe ich kurzerhand ein Paar Elac Debut 2.0 B6.2 liegend in meinen Fernsehschrank gepackt. Die kosten nur den Bruchteil einer ordentlichen Soundbar und klingen auch ohne zusätzlichen Subwoofer bereits richtig gut. Aufgrund der Größe der Boxen war nur noch sehr wenig Platz vorhanden, so dass eine Kombo aus kleinem Amp und Pre-Amp schon problematisch wäre. Damit war klar, dass eine All-In-One Lösung wie die T9 Brüder genau richtig wäre. Meine Wahl fiel dann auf das neuere Pro Modell. Zunächst die technischen Daten des T9 Pro: Chipset: TPA3250+Jan5725+QCC3031+ES9018K2M+SA9123L+OPA1656+NJW1194 PC-USB sampling rate: 24bit/192khz, 16bit/192khz, 24bit/96khz Bluetooth/optical fiber/coaxial sampling rate: 24bit44.1khz/24bit192khz/24bit192khz Bluetooth chip: QCC3031, Bluetooth 5.0, stereo, support IIS, SPDIF, HFP, TWS, aptX, aptxHD Tube model: JAN5725 (can be replaced with: 6AK1П, 6AK5, 6K4, EF95.6J1, GE5654, etc.) Speaker impedance: 4-8Ω Output power: 100W*2 (4 Ohm load) Signal-to-noise ratio: ≥102dB Frequency response: 20-20kHz (±1.5dB) Total harmonic distortion: 0.03% (1kHz 1w) Input mode: RCA/Bluetooth/PC-usb/optical fiber/coaxial Working power supply: DC18V-32V, 3A or more Size: 290x240x90mm Im Vergleich zum Vorgänger hat sich damit einiges geändert. Beide basieren auf dem TPA 3250 Chip und klingen entsprechend ähnlich. Das war es aber auch schon fast mit den Gemeinsamkeiten. Optisch fällt natürlich sofort das Display des T9 Pro auf, das es beim Vorgänger nicht gab. Auch sonst ist die Bedienoberfläche neu gestaltet. Die beiden Potis für Bass und Treble fehlen, der Lautstärkeregler (der noch einiges anderes kann) wurde verkleinert, damit alles mit dem wieder vorhandenen VU Meter noch auf die Vorderseite des sehr kompakten Amps passt. Ob einem die orangen Akzente gefallen, ist Geschmackssache. Weiterhin fallen sofort die neuen, kürzeren Röhren vom Typ JAN5725 auf, die weniger weit als beim T9 aus dem Gehäuse ragen. Das macht sie mechanisch etwas weniger anfällig für Grobmotoriker und Leute mit schlecht erzogenen Haustieren und ist grundsätzlich zu begrüßen. Auch im Inneren hat sich einiges geändert. Neuer Bluetooth Chipsatz, neuer USB Chipsatz (mit bis zu 192KHz Abtastrate) und auch sonst ist vieles aktualisiert. Neu ist auch das mitgelieferte Netzteil mit jetzt 32V 5A, das entsprechend etwas mehr Leistung verspricht als beim Vorgänger. Dazu muss man allerdings sagen, dass der T9 Pro die auf dem Papier versprochene Leistung von 2x100W an 4 Ohm mit diesem Netzteil nicht erreicht. Da die Kühlung des Gerätes aber aufgrund der kompakten Bauweise ohnehin mit dieser Leistung überfordert wäre, ist das kein echter Nachteil. Das mitgelieferte Netzteil passt gut zum Konzept des T9 Pro und liefert im Alltag ausreichend Leistung für die meisten Anwendungen. Ich habe nie wirklich Leistung vermisst. Wenn es aber mal etwas zur Sache gehen soll, muss man den Volume Regler des T9 schon deutlich aufdrehen. Die Leistungsreserven der stärkeren Amps aus dem gleichen Haus (A07, A07 Pro, A08 Pro, A200 usw.) in Kombination mit einem leistungsstärkeren Netzteil hat man beim T9 Pro natürlich nicht. Trotzdem liefert er mit dem mitgelieferten Netzteil etwa 2x75W an 4 Ohm und 2x50W an 8 Ohm. Großes Plus beim T9 Pro ist der integrierte DAC mit umfangreichen Eingängen für RCA, USB, Bluetooth und beiden Digital-Ins (Co-Ax & optisch). Gerade wenn wenig Platz zur Verfügung steht, ist der T9 Pro jeder Kombo aus Amp und DAC überlegen. So viele Anschlussmöglichkeiten gepaart mit ordentlich Leistung in so einem kompakten Paket sind ein nicht von der Hand zu weisendes Argument für den T9 Pro. Selbst ein Aux-Out zum Anschluss eines aktiven Subwoofers ist vorhanden. Die Lautsprecher werden entweder angeklemmt oder (vorzugsweise) mit Bananensteckern angeschlossen. Bedient wird der T9 Pro wahlweise per Fernbedienung (die leider typisch für Amps Made in China sehr einfach gehalten ist) oder direkt an der Front mit nur einem Bedienelement (Poti mit Druckknopf Funktionalität). Langes Drücken schaltet das Gerät ein und aus, wobei das Poti die Lautstärke regelt. Ein kurzer Druck schaltet die Eingänge durch. Per Doppeldruck wählt man die beiden Frequenzbänder des EQs aus und das Poti regelt diese dann. Das funktioniert in der Praxis wunderbar. Trotzdem hätte ich gerne auf den VU Meter verzichtet (er funktioniert eh nicht wie bei einem klassischen Amp) und den gewonnenen Platz für zusätzliche und größere Encoder genutzt gesehen. Kommen wir zum wichtigsten Punkt eines Amps - dem Klang. Ich habe den T9 Pro mit Bananensteckern und 2.5mm Kabel an meine Elac Debut 2.0 B6.2 angeschlossen. Schon beim Fernsehen macht die Kombo richtig Spaß. Kein Vergleich zur alten Soundbar. Die Omaha Beach Szene aus Saving Private Ryan klang sehr eindrucksvoll. Die Detonationen im Hintergrund waren fast schon zu realistisch und erzeugten eine tolle Stimmung. Filmmusik kommt jetzt ebenfalls ganz anders zur Geltung. Epische Soundtracks wie Conan der Barbar laden zum Eintauchen in den Klang ein. Bluetooth funktioniert problemlos, allerdings habe ich zT. auch die in anderen Reviews erwähnten leisen Störgeräusche in einem der Kanäle. Das fällt allerdings nur bei Stille oder sehr leisem Ton auf. Da ich Bluetooth als Bonus-Feature ansehe, kann ich damit leben. Andere Aiyima Geräte zeigen dieses Verhalten aber nicht, hier sollte nachgebessert werden. Ein sehr nettes Feature ist auch der USB Anschluss, bei dem der T9 Pro am PC als USB Soundkarte funktioniert. Nachdem der Treiber installiert ist, läuft alles sofort absolut problemlos. Egal, welchen Eingang man nutzt, der T9 Pro klingt immer sehr transparent mit fein gezeichneten Höhen (ohne aufdringlich zu wirken) und einem ausgewogenen Bassbereich, der bei mir keinen Wunsch nach einem zusätzlichen Subwoofer aufkommen lässt. Klanglich braucht sich der TPA3250 vor seinem beliebten größeren Bruder, dem TPA3255, absolut nicht zu verstecken. Was der kleine Amp für unter 200 Euro an Klang produziert, kann sich mehr als hören lassen. Damit verdient sich der T9 Pro locker die vollen 5 Punkte. Auch wenn der Aufpreis zum Vorgänger nicht unerheblich ist, sehe ich ihn aufgrund der durchweg höherwertigen Bauteile als gerechtfertigt an. Der T9 Pro ist ein ausgezeichnet klingender, extrem kompakter kleiner Kraftzwerg mit kompletter Ausstattung für unter 200 Euro und eine klare Kaufempfehlung.

Liten men ganska kraftig

Mi sono preso un po' di tempo prima di scrivere questa recensione per poter testare al meglio questo gioiellino. A dirla tutta non me l'aspettavo così piccolo, ma la cosa che mi ha veramente impressionato quando l'ho tirato fuori dalla confezione è stato il peso... insomma solido, compatto e con un bellissimo aspetto. Confesso che prima di provarlo avevo qualche dubbio sul fatto che potesse pilotare le mie vecchie Pioneer S-X450, casse che in effetti con il mio amplificatore precedente qualche problemino me l'avevano dato. E invece con mia somma sorpresa è andato tutto liscio, un'ottima resa a qualsiasi volume, mai un clipping ed una purezza di suono che veramente non mi aspettavo. È ovvio che non siamo davanti ad un componente adatto ad audiofili accaniti ma vi posso assicurare che fa una gran figura. Mi sento veramente di consigliarlo a chiunque cerca una buona qualità ad un prezzo più che accessibile

Very nice warm sound, though treble can be increased to your liking, multiple input points, good quality remote, high quality product according to price point. Must buy. The tubes provided are appropriate though could've been better for much better sound, like those suggested in the product details, though it would've increased the price, so no complaints at the price point. Compared to A08Pro, T9Pro has more melodic and warm sound though the chipset of A08Pro is better and newer and A08Pro supports higher power and hence higher volume and thus A08Pro is better for much higher powered speakers as it also supports 48V power supply. The T9Pro does not support 48V power supply hence will not be loud enough for high power speakers, but sound will be good enough.
