Review on Q100 2.1 Channel Hi-Fi Bluetooth 5.0 Power Amplifier Class D Mini Stereo Audio Amp Speaker Subwoofer Wireless Receiver 80W+40Wx2 Dual DSP (Black): The Ultimate Wireless Audio Solution for Crystal-Clear Sound by Louis Loebis

Good: Decent sound. I use it to power a set of bookshelf speakers and it connects to my TV, making it basically a soundbar killer. I turn the volume up to 12 (goes all the way to 31 but there's a lot of distortion) then my TV outputs the volume, essentially turning my TV into a preamp. Appropriately, there were no problems with it. The fact that it comes with a more powerful power supply was the reason I chose it. I never use bluetooth. Bad: The display is stupidly bright, and by the looks of it, it's impossible to turn it off. The only other bad thing is that it's not the cleanest sound. If you turn it up past 18 you can definitely hear some hiss in the dialogue, so I keep it at 12 to keep the audio clean as the input ramps up. Other thoughts: I never use a subwoofer output, but if it's working well, as it should, then this little amp is definitely worth considering rather than a soundbar. Update: Less than a week later, the right channel sounds weaker than the left. I'm tired of changing channels and of course the right channel uses less power. Update 2: The company helped and said that the warranty covers my defects, anyway I replaced it with Revain, this device gave me no problems. , It sounds good. I'm increasing my rating to 4 stars based on the company's willingness to help me.
