Given the OPs listed favorites, I'd suggest Peteris Vasks, Kalevi Aho, and Aullis Sallinen. I also second the recommendation of The Ligeti Project Vol. II on Teldec.
Schoenberg's Verklärte Nacht and Gurrelieder are late Romantic works, which may or may not be to your taste. I would however urge you to hear the Chamber Symphonies.
I hope the thread does not get off topic, with every composer who lived into the 20th Century being recommended.
