Do you think that applies universally to all music playback on a particular system or does it vary album by album?
It varies quite a bit from song to song.
If you have an fairly accurate system, and listen to a variety of tracks you will find yourself wanting to change the eq from song to song-ESPECIALLY on the low freq side of things.
On one song the bass is fine, on the next it is to loud, and then it is to quiet.
You have to remember that songs are mixed on different qualities and timbe of speakers.
So what sounded "right" to the mix engineer may not sound right to you.
If you find you have to turn the bass down-then that is a good indication that "mix system" had the subs that were set to low for the mains.
So the mix engineer ended up turning up the bass freq to make up for it.
The same goes for the upper mids. If the mix was done at low level-and you turn it up, they can get a bit harsh.
While if the mix was done at a high level-the mix person probably pulled back the 3-4KHz region to keep it from being harsh.
Hence the reason I insist on having the system flat-so that it is a "white canvas" upon which the mix person can "paint" whatever sound they want-without having to "counter" some particular/predetermined curve.
The problem is that most systems are "evaluated" using prerecorded material-so the "tone" of the system might be "preset" for a particular style of recording.
It could be very different with a different recording.
That-and many people simply get "sucked in" to "the latest presets"-so they MUST be better-without even doing any real evaluation.
They just "follow along with the flock" and don't want to give any real opinion-for fear that they might be ridiculed.
If you don't understand what is really happening-how can you make any useful decisions? HENCE the reason to gain some understanding of what we deal with all the time.
Or just keep "regurgitating" what others tell them.
I know this offends some people-but they simply cannot think or make decisions for themselves. And manufacturers know that.
I better stop now before I say something that will offend somebody
Sometimes the truth hurts
