+1 on Balanced interconnect/short speaker cables, @ozzy .
Rumble from a turntable is most likely due to poor isolation. Either the turntable itself, or equipment being influenced by vibrations.
Also, improperly set up subs can accentuate rumble.
It's hard to pinpoint without knowing what is in your system, how you are placing equipment, as well as how your room is set up.
You can post images in Virtual Systems. It would help alot.
