Noise from emmlabs CDSD with certain CDs

I am wondering from other emmlabs CDSD owners, how often do you encounter trouble playing certain CDs with loud spinning noises from presumably unbalanced discs ? THe sound starts off loud on the first few tracks, but usually deceases as the disc plays later tracks. I seem to be noticing this happen with more new CDs lately than I remember when I first got my system last year. Any solution ?? While I am used to this with my cheap Cambridge Audio CDP, is this to be expected with a transport of this cost ?
