Precautions for use:

1. Do not use cheap audio signal lines These lines are not shielded by themselves. High-frequency noise will be introduced.

2. The correct order of use is to connect the power supply(Can use 19-24V laptop power) and the power amplifier first, and then let the power supply be connected to the mains Power socket .

The wrong way is to first connect the laptop power to the mains mains power socket and then connect the laptop plug to the digital amplifier.

3. Use a power supply with as much current as possible. If you only use 2-3A power supply, the output performance will be greatly limited.

4.To have enough audio input and sufficient supply voltage/current, There will be enough output power.

5.The power supply voltage is higher and the relative power will be larger. The speakers with different impedances will have different output power.

6.In the case of sufficient voltage and current, the larger the ohms of the speaker, the smaller the relative sound power. Please pay attention!

Works well.
Somebody gave me an old Sony 5.1 speaker system from a TV set. I used the speakers along with the AIYIMA amp to make a 2.1 speaker system for my laptop, to use as a music station. I needed something to use in the room where I practice dancing tango.The unit comes in a nice package, and seems to be built well. One thing I really liked is the use of rotating knobs. I bought a Bluetooth speaker before this and you had to hold down the buttons to control the volume. I found that system to be problematic. Also, its nice they give you control over the sub frequency cutoff.I used the optional power supply, although I was tempted to use an old laptop supply. Also, I used the hard wire connections instead of Bluetooth.The combination of the amp and speakers won't win any contests for volume or clarity, but I am more than satisfied with the overall power and room filling sound for my purposes. I don't hear any noise or weird sound artifacts.Th unit runs a little warm, just so you know.I have not tried the Bluetooth feature yet.For the price and size I don't think it could get much better.

I use this with speakers on my desk and am quite happy with the ease of use toggling between desktop PC and phone, which I do multiple times per day. They quickly connect and provide a very stable connection with AptX support. They have no issue whatsoever powering my speakers (Micca RB42). I'm not currently using a sub, but plan to eventually pick up a passive for these to make use of their 2.1 functionality.

4.0 out of 5 stars performance as expected. Nice customer service
Reviewed in the United States on December 31, 2022
Color: A03 Black+DC 24V AdapterVerified Purchase
Update:
About 40 days after the original review below, Aiyima customer service reached out to me, which I neither expected, nor had I requested, willing to address the "problem", which was probably mostly due to a poor choice from my side of the amplifier to meet my needs, rather than anything wrong with the product itself.
This shows to me AIYIMA's / seller's commitment and support for their products, and gives me confidence to buy their products again in the future.

Original Review:
got it on sale, to drive a pair of jamo s803 bookshelf speakers + a tiny 6.5" sub in a small office room.

I had also tried a Fosi Audio BT30D: on paper the two are the same (2x TPA3116 chips, same audio power and same power supply specs). As expected [TPA3116 dual chip with a low-power DC power-supply] there are compromises in performance: when going to moderate/high volume: the AIYIMA (this one) has a distortion at low frequencies (bass) and loss of clarity at high frequencies, and it loses all its oomf/loudness-on-stereo-channels when I connect a small passive subwoofer (6.5" pioneer); the FOSI equivalent maintains the stereo channels' power and clarity, but could hardly drive the added subwoofer. Both are as-expected and good choices for desk/office amp to drive bookshelf speakers.

Construction seems robust overall, and gives a quality feeling; BT connection is good with laptops and alexa echo dot as sources. For the moment, I just dropped the subwoofer, and for driving only the two bookshelf speakers this amp sounds really good.

I connected this Aiyima amp to a pair of Infinity Primus P163 bookshelf speakers and honestly, the sound came out even better than my Denon home theater receiver. I was kinda skeptical if this tiny unit could run these speakers plus a subwoofer and it had zero issues running them all together. Make sure to get a decent 24v power adapter to unlock the full potential of this unit.
While I love the size, look, and everything, Bluetooth function is probably my favorite feature. I have a projector in the master bedroom and unless I routed the audio cable access through the ceiling, there was not an easy way to set up these bookshelf speakers by the projector screen. And this amp's bluetooth functionality solved that issue. If you're a Roku user, I highly recommend trying out Roku app's private listening feature. Just connect your phone to this amp's Bluetooth and turn on Private Listening on your smartphone Roku app and voila! You should be able to listen to whatever's streaming from Roku to your speakers.
As of now, I'm using this connected to Echo dot. While I love Echo dot, listening to music through Echo dot's speaker was never a good experience and now I can truly enjoy listening to my favorite music through REAL speakers.

Color: A03 Black+DC 24V AdapterVerified Purchase
I bought this amp a couple of months ago to power some floor standing speakers i had. So far the amp works great, all the switches and knobs to their job and it delivers more than enough power for my speakers.
Pros:
• Super easy to set up and pair Bluetooth
• Switching from aux to bluetooth is super convient
• Deliver more than enough of power (make my 90rms/150max towers clip)
Cons:
• Power supply hisses constantly when the amp is off & speakers hiss when the amp is on and nothing is playing, i might've just received a defective amp or power cable (I tested the speakers on another amp and they dont hiss so its has to be a problem with this amp)

I have a vintage car and wanted to retain the old school look of the interior - broken AM radio and all so I bought this to stream music from my phone in my car. I paired it with some JBL GTO series component speakers and an 8" compact Rockville sub under the drivers seat. All told about $200 and holy mackerel!!! Once I dialed in the sub frequency and gain, I could not be happier with the results!!! I hid the amp in my center console so to look in my car toy wouldn't know there was a modern streaming sound system hiding away that just ROCKS! I bought a 12 to 24 step-up converter to make sure I was getting everything out of this little amp but that peice of crap burned up the second I put power to it. I didn't feel like waiting on another one so I just wired it up without it and turns out I didn't even need it because this thing sounds amazing and is PLENTY loud. Can't say how it sounds hooked up to any other speakers but this particular setup is just mind blowing how clean and crisp the highs are and how low the bass kicks and did I mention - PLENTY loud! Couldn't be happier!

1.0 out of 5 stars POWER SWITCH IS DEFECTIVE!! 2 of 3 failures within 30 days of each other!

Actual package was not taped or shipped in an open box that could have been tampered with or damaged. The controls are not aligned straight and appear staggered. It comes down to how the potentiometers seems soldered as crooked soldering will result to staggered knobs.

—————

Update:
After a little over 2 weeks and “minimal” usage, the power switch behaved like the other reviewer that reported the same issue. Hopefully, this wasnt the same unit being recycled by the seller and marked as new and not used/refurbished. If this happens again, both of these amps (I purchased 2 of these) will be returned.

Es lo que yo esperaba por la potencia nominal del amplificador, coneté dos bocinas de un antiguo sistema de teatro casero que conservé y el Subwofer del mismo, satisface perfectamente mis necesidades de audio, sonido nítido, claro y sin ruido, el amplificador no se ha calentado durante las sesiones de uso que le he dado y los bajos realmente se sienten y escuchan, en verdad estoy muy satisfecho con su performance, y por favor no se confundan, si quieren mucha más potencia, busquen un amplificador de mucha más potencia para evitar ulteriores quejas
