I read this "quick fix" by this guy on the above page. It consists of wiring a 100ohm resistor and extremely high value capacitor in parallel with your speaker drivers. He says that it gets rid of RF noise that can alter the audio signal. It kind of makes sense, as the VC of a speaker is virtually infinite resistance at RF frequencies. But would it actually change the audio signal reaching your speakers? My guess is no, because RF is way out of range of audible sound. Several other people it seems have tried this, and claim to hear a difference. I think it is probably the placebo effect. Kind of like high end speaker cables! :-) Anyone else have any ideas on this? Thanks

I suppose there is probably a quirky amplifier somewhere with high enough output impedance that it might pick up RF through the feedback loop. But the output of a good amplifier should act as a direct short to RF frequencies picked up by long speaker wires and voice coils.
