In my opinion it all depends hugely on your favoured types of music.
For example, pop music with the tendency to have synth bass could indeed be overbearing with B&Ws default bass, but large scale orchestral music (e.g. Mahler, Bruckner symphonies) have relatively soft bass compared to the volume of higher pitched instruments. Having a bit more oomph from the double basses and low brass is absolutely fine. If the double bass players in reality could get more volume out of their instruments they would definitely do so in the climax of a Mahler symphony
Similarly, I love listening to string quartets and the truth is that the entire Px8 raised bass curve is completely irrelevant.
Of course, something with powerful synth bass can sound overpowered, but there are plenty of fun modern tracks where the extra bass is a bonus. I was listening to a selection of Kpop yesterday and didn't once feel the need to reduce the bass EQ below the -2dB I have it set to.
Another silly example: I like to use The Prodigy to test out hifi systems. Breathe from Fat of the Land is really fun to examine bass output (I remember how much I struggled to place my Rel subwoofer using this among other things years ago). I find that it sounds very good on the Px8s. I don't detect any bloat there, just good solid and crisp bass.
Do you have an example of the type of music you listen to where bass bloat is a significant problem?
