Cardas Caps Worthwhile?


Has anybody tried covering unused rca jacks on their preamp or a/v receiver with Cardas Caps? Another snake oil remedy or sonically worthwhile? Thanks, Ed

Installing these was one of the first tweaks I tried along with isolation and power conditioning. Not to mention the interconnect and speaker cable changes I've gone through. Possibly 10 to 20 upgrades in the last two months. And you know what? There have been so many, I can't even tell what difference most of them made.

The only difference I can be sure of was the change my new speaker cables and speakers made. And the best I can say is that the cummulative effects have been very good. I just wish I knew which products actually helped. Now I'll have to take them out one by one just to be sure.

The only contribution I can be sure the Cardas Caps have given me is "peace-of-mind", and "Oooh, those are cool looking". Or maybe that should be "delusion-of-mind".

In Discover Magazine they once ran an article on the reason why pizzas stay hot so long. They said it was because the tomato sauce was good at trapping and retaining heat. Maybe I'll stick a couple slices on my amp.
Gunbei, I like your response. The scientific method is too much for me too. I think a lot of it is just "peace of mind". I had a $1000 Essense Power Distributer at one time. I still don't know if there was an audible difference with it. I did like knowing, however, that all that RFI wasn't getting into my system.
Postes: Let us know your preamp make and model. I heard somewhere that the caps are likely to be inaudible on balanced units but might help single-ended ones.
It would be somewhat surprising if the caps made a large sonic difference in any system. It would imply that you live in a horrendous RF polluted environment. I use the product and I cannot honestly say I heard a positive sonic difference. At the same time I can say that the Cardas caps did not screw up the sound of my system -- which is more than I can say about some other tweaks I've recently tried. At a little over $2 a cap, if the only thing they do is keep the unused connectors free of dust, I think they're a reasonable value.
