I bought this because it was on sale and so far, I am very happy with it.There's no denying that this faces a lot of competition at full price (~$75 USD is what I see) -- even from the brand's own line up! Personally I was considering other options even at $50 USD since there are other options using the same chipset (TPA3166) or other TI chipset.Having said that... I'm using this to power a pair of bookshelf speakers on my desk about 3 feet away. I got annoyed by the pink noise/static of the previous amp that this replaces. Now, I was able to force the unit to create a lot of static by disconnecting the source from it and cranking all the dials to the max as a stress test. But with normal usage that isn't a problem.I can probably hear very very faint noise with my ears right next to speakers after dialing in it at about 75 dB peaks listening to music (tone control at about center/"+0" and volume control several clicks left of center) with source connected but paused (Android tablet with volume set a little over mid way/before it turns red). Definitely discernible noise with source disconnect and my ears right next to speakers. In neither case was I able to pick up any noise at my listening position.If I listen carefully with volume maxed and source pause there is faint noise but not a problem for me and hopefully people would be way more than 3 feet away in that case. It does suggest you might want something else if you plan on using this in a very large room and would really need to crank it.The unit and knobs seem well built and feel sturdy. It isn't heavy at all but for its size my brain is constantly expecting something much lighter.Getting to acoustic performance... this sounds good to me subjectively. No discernible flaws while listening to music and watching YouTube. However, REW measurements (take with a grain of salt since is not completely calibrated) show roll off below around 270 hz (part of it I know is from my speakers from around 130 hz) and and peaks and valleys from around 600 hz to around 1 khz and around 1khz to around 2 khz. Bass control is able to help a little with below 270 hz. Mid control doesn't seem to do too much for around 600 hz to around 2 khz.This is all with line inputs (RCA) so I can compare things using the same speakers driven by an older Yamaha AV Receiver (using same external DAC: tablet -> USB C -> DAC -> RCA). I did test it a little with aux input but I'm not sure what's causing more noise there. There is never any noticeable noise when there is music/content playing.Now... the only thing missing is... will have to see if this stands the test of time (what this replaced did not).Update #1: I found one song on a streaming service and I never noticed the issue on AVR setup before despite having listened to song a number of times. On the Aiyima, the harsh vibration of some sort was pretty apparent. Not sure why I didn't noticed it before on the Aiyima... maybe it is because it was towards the very end of the song and I skipped the end? I know it is a repeated section and tempo and beat is just ramping down so totally didn't expect issues there? The saving grace for the Aiyima is if I am right next to my speakers with my AVR I can hear same harsh sound but it is quite faint (so I can see why I never noticed it with AVR). Feels like the class D amp is not very forgiving of poor source/issues inherent in source/recording (compounded by fact I am using it for near field listening).

Great and easy to use, wish it sounded slightly better. But the tone controls make it very usable. Recommended

Acquistato per "ingannare" un impianto stereo Trevi TT 1072 DAB, che ha i cavi delle casse molto corti. Avendo provveduto a creare delle prolunghe in modo da posizionare gli speakers dove più mi piaceva, mi sono accorto che in questo modo la musica arrivava alle casse con qualche secondo di ritardo. Con AIYIMA A01 TPA3116, l'impianto stereo viene ingannato e non c'è più alcun problema di latenza. Mi piace davvero tanto perché è piccolo, potente e affidabile. Consigliato.

J'ai acheté cette amplificateur pour redonner vie à de vieux haut-parleurs 100w 6ohm, qui m'ont toujour bien rendu une qualité sonore incroyable et cet amplificateur, leurs rend justice !Très bonne appareil, construction solide comme un "tank" comme nous les aimons.Je suis vraiment heureux de mon achat :)

Works well with a pair of klipsch bookshelf speakers I had. I used the line out to connect to a mono aux to rca cable for a subwoofer. This lead to the subwoofer only activating with left channel signals when in stereo, something to keep in mind if you plan on doing the same. It was easy to setup and is surprisingly small for its 100 watts of power to each speaker. It has a metal construction and is well worth the 100 dollars it costs. My only wish is that it had Bluetooth, other than that, a perfect product.

Package contains the amp, a psu, and clear (though brief), setup/use instructions.Lets start at the bit that matters - sound quality. I can't find anything to complain about here. The output is clear and well balanced having treble, middle and bass adjustment - all of which work effectively and appear (to my ear), to adjust the ranges they're designed for. Very nice to have some middle adjustment (or any adjustment at all for that matter), rather than the usual treble/bass.The amp is quite compact, and the pots work smoothly and affect the sound output only in the way they're designed to - no scratchy, cheap controls here. The three-way switch (off/RCA/Aux), also operates nicely and soundlessly.I've switched to this from a cheap combined blutooth and amp device which, while decent for the money, is audibly inferior to this Aiyima power amp (for instance, the volume pot is pretty scratchy on the cheap and cheerful device).Only thing to keep in mind is if, for instance, you connect your phone to the aux-in via the headphone-out (should you still have a phone that has a headphone socket), remember that you'll need to turn the volume output down on the phone to avoid over-driving the amp. This goes for any device that you connect to the aux-in via a headphone socket and does not indicate a problem with the amplifier. Not an issue if you're using the line-out of whatever your sound source is.That's it. The price is pretty good and the sound output is even better. Very happy with mine, to the extent that I just bought a blutooth receiver to use with it. Might be time to look at some new speakers too...

Der Winzling kam heute an. TV und werLautsprecher angeschlossen, kein Problem. Der Klang ist, für mich, ziemlich gut. Höhen , Mitten und Bass sind separat einzustellen, schonmal gut. Ich hatte das Gerät bestellt, weil man einen Subwoofer anschließen kann. Nun habe ich leider nicht darauf geachtet, dass ich ein chinch auf 3,5mm Klinke Kabel benötige. Wird halt noch besorgt. Bin soweit zufrieden. Für jemanden der nicht krass audiophil ist, oder als Übergangslösung durchaus zu empfehlen. Preis-Leistung geht für mich in Ordnung. Update: nachdem ich den Zwerg jetzt einige Monate im Einsatz habe, bin ich immernoch begeistert. Dranhängen habe ich den TV, zwei Teufel Ultima 20, einen Klipsch Subwoofer ,und das Set Up funktioniert wunderbar. Sound und Bass sind sehr gut. Einziges Manko, wenn ich einschlafe und der TV abschaltet, "klopfen" die Boxen immer wieder. Also, wenn kein Signal mehr kommt? Keine Ahnung was das ist, damit kenne ich mich nicht aus. Ansonsten Kaufempfehlung.

Esta bien construido, agradable al tacto en todas las ruletas y enchufe, sonido limpio y agradable, recomiendo que este conectado a un buen dac o fuente de audio ya que necesita una entrada de audio ganancia buena ya que si lo conectas al movil directamente por cable al ser la señal pobre no podras disfrutarlo como se merece.
