Powered speakers show audiophiles are confused

Arguably the highest quality audio systems in the world right now are Level 5 Audionote, and they design every speaker, external xover, transformers, and dampening feet to match. 

And its true that audiophiles like to tinker with matching gear - because even a modest amount of matching gears at the audiophile level will vastly outperform Genelecs and lower end integrated stuff like that. So, its worth it.

What you said is not wrong, but it is also not the whole story. 

"this concept is much more important to sound quality than the vibration systems we often buy."

This is true when the transparency of a system is very low, like powered Gelenecs with something like Mogami cables. But once you move to very high levels of transparent high-grade audio components, you will begin hearing substantial effects of having the components inside the speaker versus outside or even the sound of a connector. It's not a black and white argument, it's relative to many situational circumstances. Similar to saying "I have a Prius, and all these Forumla 1 engineers who talk about the importance of aeroyamics is simply irrelevant. The difference in horsepower is far more important than the shape of a car." On a Prius, that is absolutely correct. 

Therefore, please avoid black and white thinking in audio.

"If you like to tinker, great. Tinker with the front end. But why tinker matching amps, drivers, and speaker cables when the engineer who DESIGNED the speaker can do it for you at a much lower cost?"

Because it will sound way, way better than integrated junk on the market. How can you not understand that concept? Maybe you’ve just never tried or heard it.

Theoretically when all things are designed with each other, the quality will be the top. But only something like a $1m Audionote system can do that. The products you're talking about (mainstream studio monitoring stuff) is complete crap sounding and matching up some audiophile cables and amps will sound far superior if you know what youre doing.
