RCA Caps


Is anyone using RCA caps (plugs) on their unused audio connectors?

I'm considering going with either Telos or Cardas.

I like the idea of keeping dust out of these while benefitting from EFI/RFI rejection.

Georgie Boy, if I were you I'd seriously consider modifying your post to say, Cardas caps do nothing for the sound that I'm aware of. There, that's more like it!

Another solution is to chew a piece of gum along with shreds of aluminum foil and copper shavings. Once chewed, remove the metal reinforced gum and stick it on the unused RCA plugs. Done!

Yeah, but you have to be able to walk and chew gum simultaneously.

I have had better results with Telos Gold RCA caps over Cardas. In A/B comparison, Telos caps further lowered the noise floor.  

May be I should try RCA shortening caps next....

Please note, I have taken great care of lowering noise floor and cleaning up AC signal in my dedicated room by deploying the Nordost QRT system. Our homes incoming AC aren't as quiet as we'd like to believe 😉
As long as you're going to put caps of some sort on your unused RCA inputs, might as well make them shorting caps. Why spend more for non-shorting Cardas' than for cheaper true-shorting caps? Seems obvious to me, a no-brainer if there ever was one!
