Do "Cardas Caps" make a difference?

Hi FZXguy. This is one of the first tweaks I ever purchased, and have used them whenever an RCA jack needed covering. To be honest, I don't know what if any effect they have regarding EMF shielding, it's more a matter of peace of mind for me. However, I do like the idea of covering up something that is vulnerable to dust, corrosion and any household nasty that can make it's way into a small crevice.

Fzxguy, can't speak from personal experience but I had done a bit of research into these a while back and I did not find a single user who said it made a difference.

I agree and if you are truely happy with your system and are looking for that last tweak, this should be it. I am not moving pieces around anymore and have isolated all and just ordered my sets. BTW I think they are going up from $3 to $3.75 each. I heard an improvement using a Shakti stone but I want the piece of mind if I don't.

I got a set in an auction and was able to cap unused RCAs on both my ARC CA-50 and my BAT VK-30SE (in another system), but was unable to hear any difference in either system. Like the other poster, I like the idea of neatening up my equipment and insuring against that stray RFI.

You will gain more ( on most systems ) by using / building "shunts" than by using "shields". The parts can be procured from Rat Shack and will set you back WAY less than what a set of the aforementioned "caps" cost.

The difference between shunts and shields are that shunts can only be used on unuesed inputs whereas shields can be used on any unused rca jack. As such, you can shunt the unused inputs and shield the unused outputs for maximum effectiveness. Sean
