Guys let me sum up things a bit. My opinion is really an objective point. This has nothing to do with the personal sound preferences. I'll give you an example. The other day my band recorded a demo in a studio. We got at the end a mother CD with our tunes and straight off I put the CD into the Hi Fi. A few days later the radio station played our demo. I know the sound simply because I created it with my friends. The CD has up until today no comparison to the sound from the radio. Even the recorded boradcast from playing our music on a station sounds better today than the Hi Fi playback - no matter on which Hi Fi we played it on - I mean the music from radio broadcast was the most similar to the real sound from our demo . Do you get it ? I wish most of you could listen your favourite CD played in a studio and then on your Hi Fi....That's why I am saying that source of our Hi Fi is stripped the fundamental compression and expander tools - exposing certain frequencies much more than others. If you adjust generic treble / bass that is ok but also that is no solution because you in turn put a veil on other frequencies.Still better than no adjustment. It is not so much about the scale itself it is about the given frequency spectrum that needs to be entirely exposed - just do yourself a 40Hz up to 20Khz sound test from YouTube for example. You will easily hear how many frequency dips your system has in certain passages. These dip passages in case of a radio broadcast are compensated to the listener by compression and expansion.
