I am happy with this mini amp, the sound is good with HIFI speakers. It's really nice. Although I expected a little bigger. In short it has done its job BUT I remove two stars for a power problem. Indeed this has taken an electrical connector for USA or China (I know not), there are fortunately short mini adapter except that there is a loose connection in it so it sometimes cuts is very annoying. I spent 15 minutes to find the right position and hold it with rubber bands in a certain sense. In short I now affects most, but Koolertron could provide a European catches connection anyway! Otherwise it is a universal power input then you can always buy one for less than 5 (that's perhaps what I will do).
