Review: Great Little Amp - For the price, it's amazing
Review: A100 vs Loxjie A30 - I bought this due to the efficiency of the the new chip and due to having USB audio. I also purchased a Loxjie a30 (almost double the price) . The biggest issue of the A100 is when using USB audio, if you software mute your computer or accidently turn your volume down to 0, it triggers the physical mute on the device. If you turn your volume back up on your computer, it doesn't un-mute. In order to get back sound you have to press the mute button on the device TWICE, and it takes a few seconds. Very annoying and finicky. The Loxjie A30 despite having the same chip is more efficient. It uses 1.5 watts idle and 2 watts during desktop listening. The a100 uses 2 watts idle, and 5 watts during use. The A100has a blue light that never turns off. The loxjie can go completely dark. The A100 does have a a few pros over the Loxjie. - buit in power supply - easier to change inputs - easier (when placed below your desk) to see/change volume - When unplugigng usb the Loxjie will slightly buzz the speakers. The A100 is silent Besides that the Loxjie has more advertised features that you pay for. Remote, color screen, optical in, equalizer. metal body, higher quality bluetooth, & higher quality DAC (though I couldn't tell the difference). If it weren't the the mute issue I would have kept the A100.

### ⭐⭐⭐⭐⭐ Excellent sound, super efficient
*by S***L on January 18, 2024*

I recently decided to update my entire desk setup by going minimal and power efficient. I got rid of my old gaming PC and my receiver and replaced them with a mac mini m2 and this amp. The new setup works just as well if not better than my old setup. I was hesitant to move from class a/b to class d but this new generation of class d amps sound great. It might be imagination but my BIC speakers sound a bit more punchy compared to using the old receiver setup. Could not be more pleased. There's no more waste heat that's always coming from the top of my receiver and the mac mini sips electricity at less than 5 watts during normal usage. This cut my computer usage power budget by 80%. EDIT: after using for a few weeks, I have noticed that with the volume past 50%, the amp is very noisy. So noisy that it clips without any input. I wish they just didn't allow that volume to be set, I have never actually turned it up past 25% when actually listening to anything because of how loud it gets. In the meantime, maybe avoid this amp if you have muscle spasms or if many other people have access to the volume knob. I can see these blowing out some speakers if cranked to 100% while music is playing. It clips pretty badly - yet somehow low volumes are completely fine.
