help with humming noise?


I recently bought a nak ca7 and pa7 as a second system.when i hook those two components together, the speaker emit a humming noise. yet when i try cd direct to amp - no noise. then i use my ML 336 to ca 7 no noise. ml 380s to pa7 no noise. they are all using same source and ic/speaker cable.
I am confused
what's the problem ? more importantly, how can i fix it?
