hiccup, I understand I'm a bit of a zealot when it comes to EQ. For me, it's like tweaking the colors of a painting in Photoshop to personal
No problem, surely everybody is entitled to his opinion.
But I think the examples I presented are much closer to facts than opinions. (in my opinion ;-)
The analogy to Photoshop:
A (semi) professional will also adjust his monitor to get things displaying correctly using contrast, gamma, colour correction, etc.
He will also run into sub-par quality sources once in a while. Perhaps the camera that took the picture was not adjusted properly when the picture was taken. Perhaps it was processed inbetween by somebody with a badly calibrated display, or it was optimized for print instead of for monitor display, etc. etc.
All valid reasons to make adjustments to photographs sometimes too.
(The life of a zealot will surely be simpler in this regard.
But he might miss out on some extra enjoyment... )
Your advice of lowering frequencies instead of increasing is certainly a good one.
But when you take human nature into account, if a person hears too little bass to his taste, his impulse will be to turn up the bass.
So realistically, that's just what any regular person will do.
And it's not a problem, as long as he understands he then consequently should lower the pre-amp slider.
