Review on HiLetgo Channel Digital Amplifier DC9 14V by Shawna Lamb

I don't have any equipment to measure the amplifier's power or flatness behavior, but the sound sounds great in my subjective test. I have enough volume with two speakers that when the input volume (output from computer or my phone) is cranked all the way up I can't turn the amp volume all the way up without the volume becoming painful. It offers sufficient volume for a normal-sized room. I think it would be nice in a bigger room. With the input turned off and the volume maxed out, I might only hear a little noise if I bring my ear close to the speaker, which I find quiet enough. I couldn't find any documentation, but the inputs and outputs are clearly labeled and I had no trouble connecting them. I hope to use it to create a portable speaker system.
