I love Ambre Sultan. More interesting to my nose than L'Eau d'Ambre. Sultan also lasts longer for me. I get a solid day out of it (true of most Lutens for me). If you like amber, MPG's Ambre Precieux is another great one to check out. Montale's Blue Ambre is good too - similar to Ld'A but more complex and bit edgier, less of a "comfort" scent.
