Perhaps there and with loudspeakers lacking sensitivity and having lower-than-4-Ohm impedance dips.
The audio market will respond with what people want to buy. I don't know if there is a 'problem' with 'HiFi' as much as a problem with audiophiles not knowing what they want and driving the market on that basis.
Not knowing what you want is as much an issue as lacking a reference to guide you. Do you carry a steady notion in your head of the sound you seek, or do you have a reference against which you can compare what is before you?
It can take a while (years) to learn or discover one's preferences that will stand up over time. Do you have an idea of what you want and take time trying to find it? Or, do you discover what you want by going through different systems and components until you hit on it? I suspect the latter is the case for many. If you allow others to tell you what you want (dealers, media) you may find yourself bouncing around from gear to gear.
The most important question for every audiophile is “what exactly I need?” .
I think it takes minimum 5 years to find the right answer.
Finding the answer is not easy and In this way Magazines and industry are not helpful.
There are many audiophiles who (even after 30 years) change their expensive equipments every 6 month and claim the new equipment is better.
