Yes, you need EFI/RFI shielded cables. 2 twisted internal conductors covered by a shield (an aluminum foil covering then braided wire over the aluminum). Connect the shield to the - side of the RCA at the source end only and leave the other end disconnected.
Remove Radio Station Background Noise
What is the best way to remove radio station sound from the TT feed to the pre amp?
When I turn the volume up to about 50% I can hear radio station noise if my ear is next to the speaker.
I started using clamp-on ferrite chokes that clip around the cables from the TT to the phono preamp to eliminate the noise. I wanted to know if there is a better solution or if the ferrite chokes compromise the sound.
The TT is a VPI Classic 3. The phono preamp is a Sutherland PhonoBlock and the pre amp (DMC-30SV) and amps (DMA-400) are Spectral Audio. All cables are MIT Oracle MA-X.

Dear @bigby : Really good system you own including your Benz Micro cartridge.
Well, obviously that something in your system is " acting " as an atenna when using the low level signal of a MC cartridge.
" or if the ferrite chokes compromise the sound. "" No, normally does not degrades the quality sound and you can try changing a little the TT orientation/position and the IC cables too. Sometimes these works, you can test it.
Regards and enjoy the MUSIC NOT DISTORTIONS, R.
