comparison of 508.24 VS.accuphase65,75,and emc-II

I listen to classical music and find the meridian to be a bit brittle and lacking in bass.My system includes a meridian 568 processor,ML prodigies,theatre center speaker ,script sides and REL stadium III sub.The main speakers are powered by a pair Classe 201 and the center by classe 150 in mono,the side use and old ampliwire.The system is located in my highly damped bedroom.I listen to most cd music in stereo only mode.I amlooking for a more open music specially when it comes to orchestral reproductions.Any recommendation will be appreciated.
