Uninvited radio station interference

I've just set up a tri amp tube system using horns for the midrange (2"TAD drivers), and have aquired a couple of radio stations through them. The amps, Cary 805b, have had the grounds lifted, the speaker wire is zip cord (waiting on final configuration before spending the money on better), the I/C's are stealth M7. Any ideas on where to start looking for the cure to radio interference? The zip cord? Thanks for comments.

While it may solve your radio problem, I am not so sure if lifting the ground on your preamp is a good idea for electrical reasons.

You may now have a system that is not grounded to anything anywhere. It could be a shocking experience if you become the ground if/when you touch the wrong thing.
