The modules are Gemincore amplifiers in class D (switching, not digital!) Super simple to implement: it feeds, the branch (you can put in a box too). The power output depends on the supply voltage and goes up to 120W / 8 ohm, dual 4 ohms. 1000 W peak and 15 A of current. Enough to play with the dynamics. They are of French design and manufacturing and implement original scheme.
I use these modules since their release. It was the slap when I discovered: A sound monstrous, the spectrum is reproduced with finesse, the image is very precise and dynamic to cut the breath.
The current capacity and the damping factor is very high, hence the very firm and serious down very low. The image does not float like a lot of class D amps and never feel tension on the peaks of modulation. It goes up very high and very fine through a transparent medium, open: happiness.
I tried many things before that famous little known amps (A. .. 75 something) to the big monsters audiophiles transistors, lamps, class A, class AB and D. If Gemincore does not surpass in some of the big musical monsters to several thousands of €, he plays at least in this court there, with the advantage of a huge power reserves and a relatively compact (food substantial forces) and in addition, it does not heat (try working next to a 30 watt lamps or simply to live in the summer ... or to incorporate it into a passive speaker). Okay, I admit, I'm bitten, especially by the quality / price / performance, ease of implementation (they offer to those who hate the soldering iron versions of old devices mounted as Swiss) and reliability.
