Tarun doesn't really contradict anything I say. Thing is modern European speakers are not that sensitive, neither that efficient - a consequence of balancing design and sound quality.😂 Only slightly pompous....
I agree more watts is a good thing but how many do actually need?
As you well know it very much depends on the type of music you listen to and especially it's recorded dynamic range. Also the sensitivity of your speakers and your preferred listening levels. Bass heavy techno has about 50 times the power requirement compared to a classical string quartet.
Which is why I find myself drawn more and more to Klipsch speakers, and they've just launched updated ranges.
