Is powerfull Amps only for low sensitivity speakes?

But a powerful solid state amplifier allows you to use mostly far better inefficient speakers and avoid the distortion and non-flat frequency response of many tube amplifiers. Anyway, we are not going to persuade each other.

I am very sorry you seem to be substantially misinformed on this basic principal there is no defined and verifiable factual correlation between speaker efficiency and speaker quality there are outstanding examples of each general type of speaker system of course you may prefer inefficient speakers in your Music Reproduction System to satisfy your own biases and that of course is completely fine but to claim that it is for inherent advantages of said inefficient speakers is mistaken, misleading, and a misrepresentation of clearly established fact. 

Clearthink would you please do something about your grammar? It might just add some clarity.

Well williemj I thought this was an audio group not a grammar group but since your raise dthis matter why don’t you issue me clear instructions on precisely how you would like my language to correspond to your considered ideal of how people here should communicate in the forum. Go ahead I’ll listen and take notes because obviously you have superior intellect on all things and not just audio but also now grammar. Of course it is patently clear that you are grossly mistaken about the inherent superiority of speakers of high efficiency and so I rather assume you now take issue with grammar and I suppose once this issue with grammar is resolved to your complete comfort and satisfaction you'll then raise another completley irrelevant issue such as the proper way I should brush my teeth or tie my shoes.

I reject the notion that inefficient speakers are inherently superior sounding. Not based on my listening experiences. In terms of sound quality there is much overlap between various categories of speakers . Low, moderate or high efficiency,  excellent sounding speakers exist. 

Now someone may prefer lower efficiency speakers and of course that’s fine. I just find that people who post very generalized blanket statements do reveal a lack of knowledge for a given topic. Ironically their blanket statements are presented as indisputable fact which they most clearly are not.
