AIYIMA T9 PRO 200W Bluetooth Amplifier HiFi Digital Class D Power Amp 2.0/2.1 Channel Vacuum Tube DAC Amp with VU Meter & Bass Treble Bluetooth 5.2 Coaxial Optical PC-USB inputs (AIYIMA T9 PRO)

I've been doing a lot of research on small class D amplifiers and after too many hours I settled on the T9 Pro. I am using my PC as the source and wanted an amplifier with an integrated DAC so that I could output the signal digitally via an S/PDIF cable and let the amp convert the signal to an analog one. I also have a fair bit of high res audio files and am glad the amp can process up to 24 bit 192khz signals. I am using the T9 Pro to power a pair of KEF C55 speakers that are quite large bookshelf speakers with dual 8" drivers with the top one having an integrated tweeter. They are rated to 150w at 4ohms. Now with all the preamble out of the way... all I can say is WOW! It is beyond impressive that such a small amp can effortlessly power such large speakers. The sound quality is phenomenal! I started with a 24 bit 192khz version of Louie Armstrong's "La Vie En Rose". I was blown away by the trumpet during the intro. It felt like he was right in front of me playing and the separation of instruments and sound stage were both really impressive. Once the vocals started I was also really blown away by the clarity. I next played around with a mix of different genres (I have a pretty diverse taste in music) and I felt that it could handle everything from classical to rock. The bass felt a touch low for my taste but the included remote makes it a breeze to make adjustments to bass and treble. This will be up to personal preference of course. The T9 Pro ships with a 32v 5 amp power supply which equates to 160w. If you are using this with a computer, make sure to set the S/PDIF output to 24 bit 192khz so that you get the best quality possible (if you are playing high res audio). In summary, I cannot recommend this amp enough, the value is superb for what you get. As a note, my main home theatre setup is powered by a $3,500 Onkyo 7 channel integrated amplifier so I have a great reference point at a much higher price point. It really speaks to the efficiency of class D amplifiers and the quality of the Texas Instruments chipset in the ability of this tiny amp.

Excelente equipo, brinda un sonido extraordinario. Lo recomiendo ampliamente.

I have had this little amp for many months. It’s fantastic and a great value. For a while, I did feel as if I wanted it to get better volume without maxing , but I was able to remedy this. After looking everywhere to see if I can plug this into the A07 max and basically use it as a pre amp, i decided to try it myself. I also got the upgraded power supply for the A07. (Makes a huge difference). I also upgraded the tubes in the T9 pro with the $25 riverstone audio pair from amazon. IT IS WORTH IT. Essentially, my T9 pro is being used as a pre amp with tone control and DAC into the A07 with upgraded power supply. This opened up the sound stage, gives me the volume and adjustability I wanted, and looks cool with a small form factor. I also have the x2 pre amp for my turntable with upgraded tubes. All in all for a pre amp, upgraded tubes, upgraded power supply, t9 pro and A07 max, you have a full set up that you can have a turntable attached and television. It worked great with my a/v switcher too. At one point, i had my TV, a cassette deck, and my phono pre amp all hooked into this thing running through Kef q350 speakers. it is extremely fun messing with all of the items like a lego set. THE SOUND -Turntable Get an external pre amp. The sound is crisp, and clear. Beyond impressive for its price point. It is a little thin on the bottom mid range and upper mid range, but the dynamics are awesome and you can hear the instruments in the music. I test everything with “Rhiannon” from Fleetwood mac, it really sounded awesome. I do not find that it adds to much distortion or clipping even when volume is maxed. -TV Through the optical table, it sounds great. I sometimes like just playing my playstation through a simple 2 channel set up in my small media room. It’s easy to switch from the remote and adjust the treb and bass as needed while sitting in the couch. -BLUETOOTH My 1 knock. The bluetooth on this thing sucks. The connection is fine and if you just have background listening it’s whatever. But it is VERY thin sounding. Still a great feature to have. I think you would be better set getting a blue tooth adapter. OVERALL Awesome little amp with great sound and looks. Sounds even better when paired with A07 max and upgraded power supply. For the average listener, so worth it. I mainly listen to my music on a vintage pioneer amp, but I still put this on regularly. For someone starting off on a vinyl or hifi journey, especially with a tendency to hyper focus, save and get higher end equipment. You WILL keep adding little parts to this that will rack up to be the same as just getting a few mid range pieces.

I agonised over selecting an amp that would do the job and I am really happy with my decision. This amp is running a pair of B&W 686 S2 desktop speakers and I am just loving the sound this little amp drives out. Bluetooth connection is solid. I have not bothered to use the other inputs at this stage. The remote is a nice touch also, and makes using the amp a breeze. The controls on the amp are also nice to use…I am very happy with my purchase.

En las especificaciones de la app, indica que es de 200 watts de potencia. El manual que trae el producto dice 100 watts.. El prodicto es bueno; sin embargo, si se nota la baja potencia
