I love Genelec speakers (I spent 200k +) but they are only the example of a speaker with the design concept of making an amplifier with a speaker in mind. Meyer Sound is probably the best example of this, Meyer Sound is more of a concert speaker but they sound great. A perfect amplifier only amplifies the weak original signal, it shouldn’t have a sound at all but since the very complex load the speaker gives to the amp the pathway to simple amplitude multiplication is impossible to do unless that amplifier is designed to understand the particular speakers impedance loads and the unique ways that speaker deals with frequency and how fast all this can happen among other things. I’m sure Genelec didn’t make my "The Ones" speakers with perfect amps because they of course have to keep their prices down like everyone else.
The point is that everyone knows curated speaker and amplifier design is proper but very few are doing it because the community of audiophiles are really out to lunch (I am one) we worry about very esoteric things where there are huge design concept that make great difference in proper sound.
