If you're interested in music rather than just showmanship, a better example of highlights for the organ, played as written and in excellent sound is available here .

Although SACDs don't necessarily sound better than CDs(it's been shown that converting excellent-sounding SACDs to the CD standard made no audible difference), many do because of superior recording, mixing or mastering(even on hybrid discs the mastering for the layers isn't necessarily done equally).

Enjoy the music, not the equipment.
