I operate with a 5.1 "Yamaha RX-V365" which has 5 x 100W power. The stereo operation is functioning properly. The speakers emit a clear, crisp sound, which comes across in quieter and louder setting unadulterated and naturally. At a party in my apartment I have well turned up (to -6 dB on my amp) and you really had disco feel. Rich bass and clear treble and Mittten still an apparent lightness of the boxes in this volume.
Magnat Surpreme 200 are simply top class for the price!
