Review on 🔊 LOXJIE A30 Desktop Stereo HiFi Audio Power Amplifier & Headphone Amplifier with Remote Control, Class D Amp Chip, ES9023 DAC Chip, Multiple Input Options - USB, Optical, Coaxial, RCA, Bluetooth 5.0 by Mark Turner

I loved this amp so much I bought two. The former uses the analog inputs and drives a pair of three-way bookshelf speakers that come with the Aiwa stereo system. The second uses an optical input and drives a pair of Polk Audio LSiM 703 bookshelf speakers. Both setups sound great. I tested them with music I was familiar with. Everything sounds as it should with the default EQ, so flat. They can also be very loud, much louder than is comfortable, and I didn't hear any distortion. I didn't check the Bluetooth or USB inputs, as well as the headphone output, as I don't plan on using them. FYI, you can change the color of the LED bar and have it turn off automatically after a few seconds if you want. You turn the amp on and off by pressing and holding the volume knob for two seconds. It also remembers the power state when not plugged in. In other words, if you plug it into an extension cord and turn it on, then turn off the extension cord, the amp will automatically turn on when you turn the extension cord back on.
