Small size, good looks, simple functionality, and excellent sound - a great combination. The amp looks and feels solid, no issues with the build quality and craftsmanship. The inputs look nice and the potentiometer feels sturdy. I installed the amplifier for a short test with the following setup: 19 V PSU, 2x 50 W 4 ohm bookshelf speakers, RCA in from a laptop. It sounded good - audio is clear with no noticeable distortion or noise. It was able to get very loud. Currently, the mids are strong and accurate. The highs are solid and clear. Lows/bass could be a little stronger and more rounded, comparable to my old low end Pioneer Hifi amplifier. I got a reasonable volume with this setup, it was the good time to replace the old setup with a new one. The amp didn't get warm to the touch during the 30 minute listening session. I'm pretty impressed with this little amp - great price for such a class d amplifier and I recommend it. Let's hope it will stay functional for a long time.

知人から、少し古いYAMAHAの小型スピーカーを貰ったので、echo show 5(第二世代)の音楽を鳴らすために購入。Bluetoothオーディオトランスミッタを接続して、echo show 5やスマホの音楽を流していますが、BGMで丁度良い心地良い音楽が聴けます。小型で場所を取らずに、シンプルな操作で良いです。

This is a good little amp for the money. Works fine, the supplied power supply is onlyrated for 89 watt output so I figure its only putting out 40 watts per channel not 50.However However all the other amps at this price have about the same power supply.It has plenty of gain, I got full power out driven by my mini PC, TV, Tecsun radio,pixel 6a phone through the usb c to rca adapter and an old Samsung tablet.There was no hiss listening right at the speaker with the gain full. I looks fine and seemsto be built well. The speaker connectors are ok a little small but perfectly usable.This amp is very small with an aluminum body. I would recommend it to a friend lookingfor a small cheap amp.

Sonido limpio y agradable
2026-01-08    -Javier Jiménez

El equipo es de buena calidad. Tiene un sonido limpio, la música se escucha genial y sin ningún ruido de fondo, con un completo silencio en vacío. En mi caso, con altavoces de 6 ohmios, tiene potencia de sobra para un salón de 20 m2, para mí es suficiente no pasar el potenciómetro mas o menos del primer cuarto de su recorrido. La verdad, me ha sorprendido, los amplificadores tipo D tienen mala prensa entre algunos audiófilos, pero a mí, me ha parecido que tiene un sonido muy agradable. Muy buena relación calidad precio, por poner una pega, no parece tener protección antipop y si lo dejas encendido y lo activas directamente desde el interruptor de una regleta, por ejemplo, puedes escuchar ese temido pop que podría llegar a dañar tus altavoces.

Un buon amplificatorino, molto compatto, ma efficiente, come mi aspettavo che fosse. Acquistato per utilizzarlo in una multiamplificazione, ha buona potenza , discreta qualità audio, considerato la fascia di prezzo, direi tutto sommato più che valido.

I love this little amplifier to drive bookshelf speakers. Everything you need, nothing you don’t. Built solid, sturdy connections and switches. I’ve recommended this product to my friends irl because it’s a well made product and a great value.

Vrai ampli de puissance sans souffle qui va plus fort que sa taille le laisse supposer. Boitier solide. Attention pas de réglages basses aigus. Tu peux acheter les yeux fermés

The power supply that comes with this is rated for 19V×4.74A=90.6W, and the efficiency claimed in the Texas Instruments data sheet for the TPA3116 chip is ">90%", so I have a hard time believing this thing really puts out 2x50W.But also, I don't actually care. What actually matters to me is not the rated output, but how much noise and distortion I get at the volume settings I actually use. My old boat anchor of an amp (Sherwood RX-4109) could output some kind of sound at 2x100W, sure, which is way more than I needed, sure... but even though I only needed to turn the volume dial up a little bit, that was enough to produce a nasty background hiss.Compare that to this tiny newfangled thing. I cannot hear any noise or distortion from this thing. At any volume. Sure, maybe it doesn't do 50W per channel. Maybe it does 40W. But you can use that entire range.And you don't have to. At least I don't. I have it hooked up to a Scarlett 2i4 USB audio interface and a pair of 4Ω bookshelf speakers. Even with delicate music recorded at low line levels, I have simply no need to turn the dial beyond about 20%. I'm listening to a Bach flute partita now and I can hear the flautist breathe.Now the actual drawbacks.* This is purely a power amp. It gives you no control over balance or tone. With a single pair of decent (flat frequency response) bookshelf speakers positioned sensibly, it works just fine, but there's no way to adjust it. Doesn't bother me but I thought it worth mentioning.* The only indication of the volume setting is a slight slit in a uniformly black knob. I can't see it in low light. That said, I put some paint on the knob and wiped off the excess. The paint stuck in the slit leaves a nice mark and now it's fine.* The external power brick shows no evidence of having been tested by any reputable testing house. No UL, no ETL/Intertek, no TüV, no nothing. The serial number returns no Google results. This worries me. I would gladly pay a little extra for a power supply from a reputable manufacturer like Meanwell or XP.* Balanced inputs would be nice.
