???Cartridge break in???

I just fired up a Nottingham space deck (with space arm)with a dynavector 20X cartridge. My first impression, after all of 30 minutes? Deep, subwoofer bass is not there. Very sharp , thin compressed high end. Somewhat narrow soundstage; I have Audio Physic virgos and know what the hell a soundstage is. Is this the newness of the cartridge? Or something with analog itself? What are the general characteristics of analog vs. digital? What is gained, and what is lost? thanks..........Mark
