Fosi Audio BT20A Pro 300W x2 TPA3255 Bluetooth 5.0 Home Audio Stereo 2 Channel Amplifier Receiver Mini Hi-Fi Class D Upgraded Integrated Amp for Speakers with Bass Treble Control

I needed to gift a stereo system and I really didn’t need to think about which amp I’d pick up. It was almost a given. The Fosi, suffice to say, didn’t disappoint even when paired with speakers I originally didn’t mean to buy (I was looking for the Klipsch RP400M but couldn’t find them anywhere). And once I set the system up, the BT20A simply rose to the occasion, bad room dimensions and all. My only niggle, the volume increase is not linear. Turning up the knob doesn’t do much until about 25% up and then at 60% begins to amplify the sound exponentially. And it also does not have the resistive/expensive feel of the volume knob on the BT10A that I use as a personal desktop system

Awesome product with superb sound quality. This can beat the amplifiers costs more than 10 times of its cost. I was not so confident to buy a class D amp as i always felt that class D amps lacks musicality. But this one made me a fan a Fosi audio. I am ordering P3 preamp now and wish to to try the ZA3 model too. Kudos to fosi audio for bringing quality products for affordable price. I am following fosi audio for new releases and their models will always have a place in my youtube channel techavmallu as reviews and ownership experience.

Delivers Great sound.

Excellent product

I paired it with Jamo C91 bookshelf speakers and I am just amazed how well it works. Truly recommend it!

Fosi audio BT20A pro is a class D amplifier with a small footprint. Small means very small as the size of my palm. It can produce a clean sound and a sound pressure above 100dB i guess as my Onkyo does. The bass is so powerful even if it produces 60-70 watts @ 6 Ohms. It will outperform 1K amplifier with its 200AED price tag of performance .

I recieved my package on the product box only and it is open.
