Here's a two-channel mini Class D stereo amplifier (TPA3116 50Watt) that packs a clean, mighty punch & fits in the palm of your hand! Fosi Audio has been highly praised in the home audio DIY community.
"It's little. Even smaller than it looks in the picture. But it packs a clean and mighty punch for an audio amp that fits in the palm of your hand! I picked up this simple, inexpensive 50wpc amp for use with a pair of Micca bookshelf speakers in my garage. It needed to drive the Miccas loud enough to listen beneath hearing protection, something my Lepai 20wpc x 2 channel couldn't do without tripping its output limiter circuit. But the Fosi Audio V1 can! Not only that, but its a dynamic, punchy, cool-running class D design that sounds vivid and engaging, tangible, and accurate (i.e. without the hearing protection on). I've long disliked class D amps that struck me flat and grainy, but it seems these days are coming to an end. It's got cute little low-profile banana-plug compatible binding posts and a simple, 3.5mm stereo input jack, plus a volume/power knob, and that's all. Takes up almost no space on my garage tool shelves-- less than the Amazon Echo Dot playing through it! A 36w power supply brick and some on-board capacitive reserve seems to provide enough to get the job done. The verdict? I like this thing and I recommend it wholeheartedly.
- This is a SUPER SIMPLE 2 x 50 watt-channel analog stereo amplifier that has no built in DAC, media player, card reader, remote control, multiple input selector, nor bluetooth receiver. That's all left up to the devices you plug into this thing. It is a solid, space-efficient, cool-running, lovely sounding power amplifier that drives your monitors in a sweet and satisfying way.
- The binding posts are rather close together, this thing being as small as it is. You can hardwire the binding posts by unscrewing them to expose wiring holes, but they're rather fine so don't bring your roll of 14ga lamp cord. The holes are also vertically aligned so that straight pin terminals would stick out above and below the top and bottom of the amp body and interfere with it sitting flat. I recommend banana plugs, which will plug in snugly, protruding plainly backwards from the amp without freedom of movement that would allow one terminal to short against adjacent ones."

1. Please plug the power cord into the amp THEN the wall, plug the audio cables into amp THEN switch on.
Some customers may see some slight sparks flying when they plug the power supply into the amplifier, because they use it in wrong way, you need to connect the amp to the power supply first, then plug the power supply into the 220/240v AC outlet, don't worry about the sparks, because this is class d amplifier, the capacitors need to charge when the power in, it's normal and safe.
