Relatively small, yet powerful!
Awesome amplifier, for it's size you'd never expect it to get this loud (if you supply it with a high enough voltage, it needs power to create power, preferably 34V!)

Easy to set up a pair of channels in bridge mode, it literally has banana plugs for it.
That makes it very easy to make a 2.1 setup or a 3 way active speaker (sub/low, midrange, tweeter), or 2 2-way bi-amped speakers

it isn't super quiet so on high efficiency drivers you'll definitely hear some white noise

The default program in SigmaStudio the amp comes with has a low volume cutout, so under a specific volume it wont play

Thanks to the inbuilt DSP you can very easily tune it to your room or even improve the overall response

using REW (Room EQ Wizard) and a measurement mic you can measure the response and save it, which you can then import in Sigma Studio to have it as flat as possible, after that you can apply your own EQ and have it tuned to your preference dependant on what a kind of sound you want.

Very powerfull amplifier!
This is a very good and powerfull amplifier. The integrated DSP allows you to tune your speaker very nicely. For programming the DSP please use SigmaStudio and not their own Miumax software. The Miumax software cannot write the config to the amplifier itself but only store it in the ICP5 programming module. So you have to keep it connected which causes a very loud pop when you turn on the amplifier and causes crackling/popping noises at a louder volumes.
If you use Sigmastudio, you can write the config to the amplifier so it will be saved if you turn off the amplifier.

The amplifier itself is build very nicely. I can't hear any hissing noise when it is turned on! It also does not give a feedback signal when you connect to it via bluetooth or power on the amplifier. For me this is a good thing, since i don't like the feedback tones and voices that most chinese amplifiers have.

Overall, for the money this is a very good amplifier board with a lot of functionalities!
