$1000? Apart from oud oils, I'm not sure there's anything > $1000. Therefore:
JAR Eclair (or Bolt of Lightning): striking tuberose. Most other JARs would fit the bill (eg Jardenia cheese gardenia, Jarling heliotrope bomb, etc). This may actually get close to the limit, I believe it's under $1000, but only for 30ml. But it's very concentrated, and you only need a drop. The other JARs should be below the limit.
Parfums MDCI: Enlevement au serail (sadly discontinued) or Promesse de l'aube. Superclassical.
Lutens Sarrasins; one always needs a Lutens paris exclusive.
Malle Portrait of a lady: sheer power.
Amouage Gold man: power oriental. (but subject to testing. Amouage has reformulated most of the stuff).
Of course, most BNers would not understand your problems. You can do what museums do. Keep a core of best of lot on constant display, and rotate the others, periodically moving some pieces into storage and bringing out others.
