Hello, my system doesn't provide a balance audio reproduction. My headphones have so much bass than needed, I think this affects all the frequencies like mids or highs. So I did some research and look for some audio test to do an eq preset. So finally, I have my preset done. I reduced about 4 or 5 db the bass frequencies especially 125 hz. The mids are untouched but I improved the high frequencies about 3 or 2 db. Now, I get a better and less muddy sound. My question, how this affects the overall quality besides balance and the sound profile. Is it as effecitive as having a flat sound without any eq outside of the box? How soundtage and imaging could differ with the new changes in frequencies?
