Combine equal parts water and sugar in a small saucepan. Bring to a boil, stirring to dissolve the sugar. Let cool, and then chill before use.
Fill a large pitcher with ice, and then add the brandy, liqueur, lemon-lime soda, Cava, lime and orange juice. Stir. Add simple syrup to taste.
Garnish glasses with orange and lime slices and cherries.
