The responses surprise me from audiophiles.
Unless one has studio monitors, I would assume it would be highly dependent on the speaker set, amp, placement, etc, etc.
In other words, the answer would seem to me to be: It depends...
This is, in fact, the answer.. As someone who installs home theatre systems, and them calibrates the audio, along with screen calibration - it really is a unique setting for each individual space. I could tell you the setting in my Marantz receiver, but they are set based on my speakers and room, an dbe completely useless to anyone else but my system in that room, as it is now.
These are the rules I go by:
1. Buy the best equipment you can afford, which you perceive to sound great.
2. If you use speakers, then experiment with their room placement as best you can.
3. Adjust sound volumes from within the game to mix as you best perceive it.
4. As a last resort, if you perceive an unbalanced audio spectrum then apply careful and moderate use of equalisation.
5. Human hearing and perception changes over time, so you'll eventually go back to step 1.
I'd say one more thing too, although this is very much personal opinion: Avoid applying equalisation just because you can.
While this seems fair enough, th eproblem is, most people are clueless as to what something "should" sound like, and even what sounds good. this is also true for video - the number of people I see going into hi fi stores, looking at the big screen TV's saying how "amazing" the imag elooks - when in fact, th econtrast is way too high, the screen is so bright it'll cook a duck at 100 yards, the colours are set so high that the reds are bleeding like crazy, greens look unnatural, and let's not mentiont he fact that most TV's overscan, so that lovely 4k content is cropped by 5%, and then rescaled, which kills the detail, and destroys th epoint of buying such a hi resolution screen to begin with.
Audio is the same (people usually like the bass way too high, treble also overdone, with no mid range...).
Sadly, people need to sit down and listen to properly set up equipment to understand what good sound is. Sadly, most people prefer to suck up the marketing departments ideas of "good" when it comes to audio and video, not the people who actually know...
