Hi Xicu,
Do not sell or change your speakers yet. I feel your Yamaha AV receiver is not up the task driving your MA Bronze 5 well.
You are located in the Netherlands, Find a dealer with these speakers and demo a stereo amp. Hifi Studio One in Leiden or Hobo is a dealer.
PLease try NAD/Marantz/Cambridge/Cyrus amplification.
