Review on 🔊 Fosi Audio BL20C 320 Watts Bluetooth 5.0 Stereo Audio Receiver Amplifier 2.1 CH Mini Hi-Fi Class D TDA7498E Integrated Amp U-Disk Player for Home Passive Speakers Powered Subwoofer - Power Supply Included by Rachel Johnson

I chose this amp over other amps and bluetooth receivers as I have seen a flatter response than others (approx 20Hz-20kHz +/-1dB). The power output met my needs too, and the EQ and aux channel were a bonus. Haven't tried the extra channel yet, but when I turn the frequency knob I can't hear it doing anything with the crossover. You may need to hook up a subwoofer to hear the difference, idk. I wish the EQ had a notch and a pronounced mid so you know exactly where the mid is. In addition, the crossover frequencies should at least have a common name so that you have at least a rough idea of what frequency they cross at. All in all a pretty good amp. Definitely worth the price. Excellent, quiet, clear sound, powerful amplifier at a small price. Pretty loud at 11am with my 6 ohm studio monitors.
