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?

I made up shorted RCA's (guess these are shunts) for the unused inputs on my Radio Shack battery powered phono preamps (two used as dual mono's, thus unused inputs/outputs on each unit) and soldered 100 ohm resistors across RCA terminals and placed them on the unused output's of the preamps. The results: even quiter phono stages (these battery powered units were very quiet to begin with) and just better overall sound. As far as the Cardas Caps go, I have never tried them and instead used rounds of tin foil (on unused inputs) in the past. There was no difference in the sound, that I could hear, but I figured that they would help block dust (especially on my Musical Fidelity amp which is not a lot of fun to open up). I don't bother with them on "open" tube gear.
