Horowitz is able to play everything more than well.... But Scriabin music ask for a magician dedicated to him in a total devotion ( like Wagner and Beethoven ask for total devotion)...
He is not my favorite in Scriabin, for example Igor Zhukov is better for Scriabin but who know him ?
Physical time has nothing to do with musical time, physical time is measured metronomically or with an hour glass or a watch...
Musical time cannot be measured by a metronome, there is a "beat" in it that swing for some heart as another heart and cannot be measured... Musical time result from the encounter of the heart of a musician with the heart of another musician ( a collegue, a meastro, a composer ) then cannot be measured, it surge one moment to the next imprevisible...
It is like that Scriabin must be played... Scriabin ask for another musician because his goal was awaking humanity... On this he differ from Bach who serve God, and resemble Beethoven more than Wagner ( Wagner use an ideology on which and from which his music is born).
I discovered also that Liszt also like Scriabin is almost impossible to play for the same reason ...
I begin suddenly to be moved by Liszt now who became one of my God thanks to very few pianist able to play it...
Scriabin is born not only from Chopin but from Liszt like a blacksmith in his forge, scuplting iron in the form of blooming flower.
Here what Debussy has to say about his contemporary Scriabin:
«This is a recording from one of Debussy’s concerts. He performed this piece after traveling to the Gobi Desert. Debussy remarked once during his tour: "Even composers like Liszt, Beethoven, and Chopin could not reach the complexity brought by Alexander Scriabin." "I have never seen such genius in a piece."»
listen to Debussy playing Scriabin:

I must add about Debussy that i discovred him with Ivan Moravec, a god pianist also who put me to ecstasy able to play the "cathédrale engloutie" so well i see the cathédrale before me appearing... Since i bought all albums of Moravec...He is my third God pianist.
Even with the bad recording we can hear that Debussy get scriabin right. it is incredibly moving ..His playing is delicately chiseled with a timing sense extraordinary which prove out of any doubt that he understood Scriabin and not only loved him.
Compare to Sofronitsky interpretation the God pianist of Scriabin in his daughter opinion and in the mind of all Russians :
Sofronitsky and his volcanic playing :

Now listen Scriabin himself as "recorded" by mechanical method :

Scriabin is the greatest pianist with Liszt ( i discovered Liszt with
my second interpreter with Sofronitsky/Scriabin)
Is this extrapolation close to what you were getting at?
BTW, I will be listening to Scriabin this week. I have a feeling that Horowitz is not on your list of people who play him well.
