beyma 10p40 minimal amp?

I'm not an expert but looking at specs I found that the UcD180 Amplifier Module is a 180W/4ohm power amp module. I don't know but the Ucd400 module (400W) looks more convenient for the 300W driver if pushing to much from it.
The HifimeDIY T2 Amplifier, Tripath TK2050 T-AMP is a 2*[email protected] or 2*[email protected], so weaker in comparison, but for testing I think they are very fine...
