Nope. Harman bass is extremely overblown compared to a neutral curve. People like bass. That doesn't make it accurate to reality.
I'm not saying DF -10dB is better. It isn't! Diffuse field is insanely bright as a target. Harman matches closer to reality if that bass shelf is cut down by about half or so, then it's pretty close to a set of speakers.
The Etymotic curve is more or less Harman with flat bass, and sounds... right.
I think the main confusion is the term "neutrality".
what does it actually mean?
old school audiophiles seem to have a broken definition for that, and I will explain why it is broken:
"a perfect speaker in a room is neutral because it will reproduce the music like it was being played live in my room".
as good as this sounds, it is a totally flawed concept since no music in history ever was recorded to use the ambience of your (very bad) room.
stereo recordings started with the idea of reproducing the recorded(!) ambience and reproduce it at home.
like what happened in several other art forms, reproducing reality made way for abstract creations and nowadays music is created with an artificially created ambience.
in that sense, neutrality can only be defined as: "distorting as little as possible what is in the recording".
so it is mathematically impossible for a speaker that is perfect in an anechoic chamber to be neutral in a room. for this to happen the room would have to be neutral.
the real question is: should we care for neutral? most probably shouldn't. what sounds good should be the goal. And if the majority of people like the bass boost, then this is the best target for the majority......people should just forget about "neutrality" when seeking preference.
