I have a CAT sig. mk. III and although I have only heard a BAT preamp once( I dont remember which model ) it has been my impression that the CAT gives one of the largest soundstages around. This is all also dependent apon one's other equipment, speakers, room set up, etc. The CAT also has a rich prominent midrange. A great preamp for Jazz, classical , voice , etc. Also one of the better phono-sections. Hope this helps-Jim
