  • Bluetooth 5.0 Amplifier: Featuring two Texas Instruments TPA3116D2 chips, the BT20A delivers powerful and...

Our top pick for overall audio quality and budget is the Fosi Audio BT20A. This mini stereo amplifier packs powerful performance at a great price.

The 100W x 100W mini amp had no distortion, even at max volume. The sound quality was clear and impressive at every turn of the dial. 

As one of the most powerful options integrated amps on this list, it runs well with tower speakers and desktop speakers alike.

The BT20A gives you the choice to connect via standard RCA or Bluetooth 5.0. The RCA connection gives a slightly better sound, but the Bluetooth provides great quality with an expansive 50-foot range. 

Connect to any device that has Bluetooth, including an iPad, any phone, a laptop and more. The unit will automatically connect to the last Bluetooth device it was connected to. 

This can be both good and bad. If you live alone or are the only one connecting your device, it’s a great feature. However, it can be a bit frustrating if you have multiple people connecting. 

You may need to hunt down the last device that was connected and shut off the Bluetooth. We recommend using the RCA for a permanently connected device instead of the Bluetooth option.

Convenient bass and treble digital sound control features allow you to fine-tune your sound, and it fits well with desktop or bookcase speakers. 

While its multi channel amplifier design wasn’t our favorite, it still looks good as a desktop audio amplifier. That said, it’s easy to hide somewhere while still producing top quality if you don’t want to look at it.

For audio enthusiasts who want a balance of cost and quality, this integrated amplifier is your best bet.

2. Nobsound 100W Power Amplifier

The Nobsound 100W Power Amplifier has dual 50W x 50W output and is perfect for your indoor passive speakers. In fact, we didn’t notice any difference in sound between this and a full-sized amp. 

We put this high on our list of the best mini stereo amplifier options because of its impressive amount of connections as well as its crystal clear sound. 

We didn’t notice any distortion, even over Bluetooth. No pops, crackling or hissing. It only produced good, crisp audio quality. 

Though it lists outdoor use as an option, we wouldn’t recommend it unless you had a smaller, semi-enclosed space. Of course, your experience may differ depending on your sound needs. 

If you’re not looking for anything super loud, this could be a delightful addition to your outdoor space, especially if you have an outdoor WiFi extender to enhance your music streaming capabilities.

The Nobsound supports RCA, AUX, Bluetooth 5.0, TF Card and USB audio input options. It can handle anything you want to connect it to, whether it’s a phone, tablet, computer, TV or CD player. 

Better yet, it even supports WAV, APE and FLAC formats on the TF Card input. We liked that it gave so many options while maintaining a high standard of sound. 

However, we did find that the physical connections performed slightly better sound-wise than the Bluetooth connection. Fortunately, the difference in quality was negligible.

If you’re looking for a high-quality, multi-functional mini stereo amplifier, this one can compete with the heavy-duty options. 

It’s important to mention that the design and feel leave something to be desired. The device is lightweight and almost feels cheap, but the quality outweighs the design all day long. 

For the price, the sound and the sheer number of features, the Nobsound is an excellent option.

We absolutely love the sturdiness and look of the Loxjie.

Beyond its looks, this home integrated digital amplifier it packs a punch with a high power fidelity Class-D power mini amplifier chip. The Loxjie A30 is one of the best-performing devices we found. 

It’s not quite as powerful as the Fosi BT20A, but it still works for whatever you may need it for. Its huge sound has no distortion, no hissing, and clear highs as well as confident lows.

In addition to all of this, it also has Bluetooth connectivity. This means it has streaming capability.

We’d recommend this to anyone whose needs fit within the device’s limited functionality. Nevertheless, it boasts a minimalist design with maximum sound.

This budget unit is probably the most compact stereo amplifier. It measures just 3.5 inches across. However, it has more features than most of the larger amps. 

With Bluetooth 5.0 capability as well as RCA, AUX, USB and speaker/headphone output options, there isn’t much it can’t play surprisingly well. 

At a fraction of the price of almost any other stereo amp out there, you’ll be impressed with the quality.

The Douk wasn’t as clear at the highest volumes as the other devices on this list. That said, it had enough power supply for indoor passive speakers. Its 50W x 50W output makes it competitive with other mini amplifiers. 

If this fits within the needs of the sound output you’re looking for, this device should definitely be a contender. 

We loved that you could tuck this little unit away as well. It is a great choice for those with little to no shelf or desk space who still want a smooth sound experience.

While you likely won’t expect much from this little unit since it doesn’t feel or look like it’s going to perform well, it will blow you away with its quality.

It’s also the first device on our list to feature a remote control. This may end up being a crucial feature depending on what you’re looking to use it for. Control the mode, volume, bass, treble and more.

The Bluetooth feature has a respectable 40-foot range. However, the device you’re connecting with needs to remain within a sight-line. It is not as clear if people, items or walls are in the way. 

This device manages an impressive amount of sources well with clear sound. It is a great machine if you’re looking for some fun.

While this mini stereo amplifier does come with a remote, it’s relatively useless since it only works when using USB or FM radio. If you’re hoping for control while using anything else, you’ll have to adjust it manually.
