I think Doug's answer sums it up best. Classical music does place more demands on the playback system. Noise of any sort tends to be exaggerated during quiet passages which are common with classical music.
I too did have problems with classical stuff. I solved them by :
a) changing my cart - the old one after 7 years of use tended to be noisy
b) getting a better RCM - the PRC 2.5
c) getting classical LPs from better sources and/or better quality - very few VG+ more NM or even sealed copies
Although my system still picks up noises, after vigourous cleaning, 2 rounds on the PRC with a alcohol/detergent then wash, I am quite certain the LP is cleaned to its best extent possible and hear more of the music than noise. The PRC managed to save some really dirty stuff and restored them to good health.
