There is a very famous recording of this Prelude by Horowitz produced in Moscow Conservatory in 1986. I urge you to use the best speakers or headphones to compare sound of this piano with that recording. Mind that Horowitz's recording is made in one of world's best sounding concert halls on the best equipment and mastered to perfection.
This video is home simple stereo recording, no sound processing of any kind, raw sound.
