What artist wants playback to be anything other than sonically extraordinary?
Most commercial pop records have levels that are clipping and the artists dont care. All they want is the loudest mix so that it stands out. Quantity over quality. These pop recordings are enjoyed by millions of people on their ear buds or phones or laptops. Sound quality does not enter the equation. As long as it sells its considered a success.
Most artists and musicians are not audiophiles. Ive said this before. They do not belong in our world nor do they understand it.
Studio monitors are tuned in a certain way to focus in on certain areas of the mix. The NS10 is tuned to the mids. ATC are also similar in that respect. That is why every monitor sounds different.
An audiophile speaker is designed for pleasure only. If mix engineers wanted to use audiophile speakers they would. But they dont want a good sounding speaker they want a bad sounding one. Hence the emergence of the studio monitor market.
If ATC were that good they would be the only choice. But there are dozens of monitors on the market and every engineer uses multiple monitors because each monitor is tuned to different parts of the spectrum.
Theres plenty of complaints about ATC online you just need to do your research.
