That's not correct, the new FW V5 "Default" preset is close to the old "Music" preset.
All FW V5 presets gained some more bass.
The chart show the difference New Presets relative to Old ("Music"), not absolute values.
- The orange curve shows the global equalizer change that affects ALL new presets,
- Green is the new V5 "Default" compared to the old "Music".
So if you liked "Music" before you can use "Default" now.
If you liked "Default" or "Flat" there is no equivalent.
The bass boost mainly results from the better channel matching,
Before the right channel was weaker in the bass range because of different acoustics of left and right cup.
The bass boost does not sound overwhelming and does not reach into the midrange.
In fact 200-500Hz is slightly dialed back.
I can hear the little bump at 700Hz in a few flute and recorder pieces. It can give a tiny bit of a honky sound, this was not audible in Pop music.
The 1dB reduction above 4kHz softens the sound, on cost of some sparkle.
The effect is bigger then the graph might suggest, because the new bass characteristic contributes to this.
If you ask me which FW I like better I am ambivalent. The changes aside described above clearly are a step forward.
The new characteristic fits to a lot of the music I listen to.
If we now get at least one preset (I'd change "Flat" which is 99% the same as "Default") with more sparkle I would be completely happy.
To show the improvements in the channel matching Old FW left/rigt (blue)
FW V5 left/rigth ( red traces) - much closer match.
