Unfortunately, I can only make the comparison from memory, since it's been over a year, since I had the 009S at home.
At that time, I made a direct comparison to the Utopia.
The Utopia was my winner.
And the LCD-5 has replaced the Utopia.
I
clearly consider the LCD-5 an upgrade to the Utopia, so I can only conclude (as I said from memory, that the LCD-5, is also an upgrade to the 009S).
Perhaps the text that I wrote at the time of the comparison of the Utopia to the 009S is interesting for you.
A few hours of listening later:
First of all, looks and touch quality.
The Utopia clearly has the edge here.
If I spend 4000 € on a headphone,
i expect to be able to feel and see that in some way.
That is given with the Focal, not with the Stax.
Before i come to my sound impressions,
i must mention again that both KH are set according to Oratory's EQ settings (Harman target).
Without this, the 009, would be completely unusable for me.
Very bright, strongly mid-emphasized, and extremely low bass.
So I would describe the 009
"stock" describe.
In other words: my personal nightmare.
Adjusted according to Harmann, both headphones are on par.
Both are a hi-fi revelation in my opinion.
The Stax completely stress-free, extremely high-resolution, and indescribably musical.
The Focal equally stress-free, incredibly dynamic and energetic, and almost as finely resolving.
The biggest surprise for me was that the Utopia showed the 009 what to do with female and male voices.
These sounded more harmonious, more present, more engaged, and above all more emotional on the Utopia.
In addition, the Utopia has a better "grip" on S-sounds.
The decisive factor for me is ultimately which HP can convey more emotion,
and there the Utopia is my personal winner.
Whether Mark Knopfler or Xavier Naidoo, they "had" more feeling on the Utopia.
But as I said, actually, both are on par.
Each track brings new insights.
The trumpet on track #3 sounds sharp (almost squeaky) and unnatural on the 009, despite EQ.
Quite different on the Utopia.
Here it sounds much more natural, balanced, with a pound more substance.
