Review on 🔊 Fosi Audio DA-2120A Bluetooth Amplifier Stereo Hi-Fi 2.1 Channel Wireless Stream aptX, 24Bit/192kHz Class D Compact Mini Power Amp with Integrated USB DAC Coaxial Optical, Subwoofer Support & Remote Control by Dustin Schultz

Compact, I tried Bluetooth (connected to my phone easily and reliably, despite asking permission to access my call log and contact list - right? Spyware? But it still worked when I denied those permissions ) and I tried AUX. The sound is good and I bought new speakers to make it shine. I will change this to five stars if it still works in a few years. In practice, however, the guarantee is only 30 days (Revain return). I really won't pay for international shipping to get warranty service in China. The company has several good products. If success continues to increase, they should consider signing a contract or opening a service center in the US. This would make their guarantee much more useful. Overall I really like it and the remote works well too (you can use it to adjust bass and treble). Lots of noise/volume with my new speakers.
