Honestly, in my limited but enthusiastic experience with the ES520, it's more "reliable sidekick" than "glamorous rockstar." While it won't replace the nuanced touch of a concert grand, its weighted keys and realistic sound dynamics hold their own for home or gig use—your living room might just become the next symphony hall. Not a complete letdown for your hard-earned cash, just don't expect Beethoven to personally applaud your performance.
