As someone who also enjoys music in this vein, I'd recommend trying Ravel, Mompou, Janáček, Satie, Delius, Busoni, Milhaud, Fauré, Schubert, Liszt, Domeniconi, Sibelius, Ligeti, Messiaen, Xenakis, Martinů, and Scriabin among others I'm forgetting (in roughly decreasing order of likeness). Like you I don't get much out of most earlier classical music, with the major exception of Bach, or out of totally atonal stuff either.
