I think the way to appreciate a really fast player is to "stand back" and let the piece as a whole wash over you. I am very fond of Claude Monet's paintings. If you look at them up close, all you see is a lot of comma-shaped marks. Stand back and the picture becomes clear. With music, it's obviously a mental "standing back" , but the principle is the same. All the notes together are meaningful; if you try and follow each one, you're lost. But not everyone can like everything, of course.
