Getting FM from my speakers without a receiver???

Bad amalgam fillings you say? Would be cheaper to replace analog gear than pay $$ to my hi end dentist. I am researching wiring upgrade presently and that route sounds like it would improve the sound quality anyway.
The station is Fm and they do not broadcast a duplicate signal on Am to my knowledge.
What could I place over cables to shield them?

Do you have any gear with a switching powersupply?
Such power supplies operate NEAR Intermediate Frequencies of both FM (some) and more common AM radios. I have no basis for thinking this could actually happen.
As for shielding, a better cable would work better than either copper foil or mesh around wires. It would be a mess to boot.

Have you tried a power conditioner? This goes back to my first line in this post... It may be coming in over the power lines, though the phono pre seems 'the magic bullet' .

post if you find the final root cause / solution

Yes, all gear is connected thru an APc power conditioner.
Thinking about a wiring upgrade for the Basis TT, since this would improve the sound and perhaps provide shielding that is not on the current cable.
