The Hifiman is the most comfortable. Followed by the Utopia.
From the sound of course all three are absolutely world class.
Where I felt the change from the Utopia on the LCD-5 as an upgrade.
The weakness of the Utopia is the sub bass, and the very slightly metallic timbre (cause of this is in my opinion the beryllium).
The weakness of the LCD-5 is its rather aggressive midrange and treble.
I don't mean the tonality, which I always adjust according to Harman anyway.
It is a basic characteristic.
This has also ensured that I sold it again.
Even if I try hard, I do not find any significant weakness of the HEK.
It already brings a lot to the table, which for me makes the perfect headphones.
The strength of the Utopia, is a very intimate presentation, which is especially beneficial to vocals.
The strengths of the LCD are its incredible resolution and a unbelievable bass
However, in my opinion, at some point a level of resolution is reached, where even more becomes counterproductive, as it becomes too exhausting for the brain.
No one needs more resolution than HEK, or Utopia.
If you now add the price, the HEK is clearly my favorite.
The HEK's greatest strength, compared to the other two, is it's ability to just make everything sound good, as mentioned several times before.
Another example from yesterday:
RZA - In Stereo.
One of my favorite albums from my youth, which I listened to yesterday, for a long time again.
I can not repeat it often enough, it's just incredible, even this junk recorded album, sounds pretty good on the HEK.
So I do not know this album at all.
What more could you want, than a magician, who makes your favorite music sound good?!
