From my experience, blanket statements should be avoided at all costs.
The fact that "your speakers" and "your amplifier" worked in "your listening space" with "your music", doesn't mean much when you change all the parameters and certainly shouldn't be the basis of a recommendation to someone else.
In my case, the increased power from 50WPC to 200WPC made a significant improvement. My speakers have an efficiency of 85dB.
