AK55 is not 900 watts, not even 500 or 100. It is comparable to my old Pioneer amplifier with effective 40+40 watts and can drive a pair of high-power Allison speakers. The sound is purer than expected, as long as the bass and treble controls are at maximum or almost. It allows karaoke with 2 microphones, reads MP3 files on a USB stick, and connects to Bluetooth easily. At home, with a good pair of speakers, it is truly extraordinary. Excellent value for money

It’s amazing that you can buy an amp at this price.
Discussing build quality and sound quality is meaningless when considering the price.
I purchased it for use with Bluetooth connectivity and am very satisfied.
The source is a PC or smartphone, and the output is an old Bose Wave audio speaker.
Since it was impossible to replace the capacitor of the Bose Wave, I only disconnected the speaker cable externally and connected it to the amplifier.
The power of the amp is sufficient and I am very satisfied with the results.

Delivered more than I expected for its value, clean sound without background noise, was able to power some Sansui SP-X9 without any problem. I just got them today and I hope they won’t get damaged for any reason. According to reviews, they continue to work well despite months.

Well, in principle, I have it connected to two speakers from an old mini system, it sounds very good and loud. We just need to see the durability. The best connections are optical and Bluetooth.

I am really happy with this purchase. The amplifier works perfectly with my passive speakers and offers powerful, clear sound with good bass and treble. The Bluetooth connection is stable and fast, the FM radio sounds great, and the auxiliary input allows connecting any device without complications.
What I liked most is the remote control: you can have the amplifier hidden in a cabinet and control it effortlessly from the sofa, which is very convenient. Furthermore, it is very easy to set up, even if you have no experience with audio equipment.
The design is compact and discreet, it doesn’t take up space and blends perfectly into any environment. The quality-to-price ratio is excellent considering all the functions it offers. It is ideal for both home use and small karaoke or audio systems.
In summary: versatile, powerful, comfortable, and of good quality. Highly recommended purchase!

This is an excellent piece of equipment, easy to set up and the sound from my speakers is now superb due to the treble and bass . The lcd display adds a welcome touch of class all in all this is really good value for the price paid and i would recommend to anyone who needs to enhance their sound system .

I am very satisfied with the ak55 amplifier. It works as intended. The quality of the sound depends completely on the speakers you use. Bigger three way speakers produced better sound and more bass than other smaller, two way ones. You will only need an active subwoofer if your speakers are not so good.
The amplifier is very efficient. With volume at 25% the power consumption was just 1.5w and it was loud enough to enjoy at 1.5 meters distance. At 50% it made highs at 4w and was very loud without distortion. Talking about 70w + 70w makes no sense. I have also tried a 12v, 1.5a power adapter and it was more than enough, unless you want very loud music for bigger spaces.
Connectivity and remote control response are great. My only complaint is you need to click the switch to 0 to really disconnect the static from the speakers. Standby is not enough.
I have connected it to the tv via optical cable and the sound is quite good. Very fast delivery. Recommended seller.

Very well-designed small amplifier. Works perfectly. Power: ok – Fm: ok – Blue: ok For the price, you shouldn’t miss out on it!!! The remote control works perfectly even at a distance of more than 3m.
