The amp was easy to install and worked right out of the box. But I immediately noticed a mild background hum when it is in the idle mode. When connected to an audio source, the sound quality is reasonably good, with a very good range of bass and treble control. It easily powered my 100 watt speakers and produced clean audio. As stated by others, the remote control buttons have to be pressed hard and the range is not very good. The power button on the remote does not actually turn off the power, it just mutes the sound, but the background hum is still there. There is a power switch on the front panel of the amp that disconnects all power to the unit. Digital audio files played through the USB port come through much louder than analog inputs through the front aux jack. The LEDs that show output level are annoyingly bright. With all that said, I am enjoying the amp as it now fills my needs. I opened the unit and unplugged the wires going from the audio level LEDs to the rear board, no more annoying lights. I found that rotating the volume knob to the mid range reduced the background hum. I further reduced the hum by replacing the 3300 uF power supply filter caps with 6800 uF. The hum is now barely noticeable. For the price, this amp delivers good sound and is well put together in a compact package. If you can live with the mild background hum it is otherwise a good value at under $60.Read full review

Just blew up as soon as I plugged it in. First, I thought some kind of bomb went off. It blew out with loud noise and some smoke and burning smell. Never got to use it at all.
