Do "Cardas Caps" make a difference?


A new inexpensive, and quite compelling, tweek are the caps George Cardas makes to cover unused input and output jacks, therefore rejecting stray EMF. This is a logical tweek, and I trust George's integrity here, but my question is: How noticeable is the improvement? Can everyone who has tried them hear a difference?

Is this what Sean is talking about? I have a YBA Integre DT amp in a small system in my home office. If the tuner is on I can hear the radio faintly as I go by an unused input when turning the input selector knob on the amp. If the CD player is also playing I can hear both (or just the CD player if the tuner is off). If I go by a used input where the component is plugged in and is not turned on, it is dead quiet. Therefore, when an RCA cable is plugged into that input, I do not get any sound if that unit is off, which is desireable. So a cap would do nothing, because it just covers the hole, but a shunt goes in the input and will cut-off the noise? A trip to Rat Shack is in order then! Thanks!
