Cardas Caps Worthwhile?

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.

The homemade version helps. It reduces noise level tremendously. Yes, I live in a horrendous RF polluted environment, NYC. Even when people walking in the room, the noise level changed, NOT ANYMORE!

It all began 3 months ago when I installed my preamplifier into my system. The annoy HUM jumped out from speakers! Moved cable TV to the other room and cheated all, except one, plugs, the noise was reduced but still noticeable. Last week, tried to cover all unused RCA connectors with surplus interconnect cables without connecting to anything. I AM PACIFIED AT LAST.

I am open to any suggestion(s). But if you have the same problem as I did, try inexpensive surplus interconnect cables that come with TV set or DVD player for temporary solution first before spending money on Cardas RCA cap.

I use small rounds of kitchen tin foil on the back of my Musical Fidelity amp (which fall off if you fuss around too much), for dust and air grunge protection. I wouldn't mind having the Cardas Caps instead, but am too cheap.

Hi Dekay, maybe you should buy one set at a time as I did. I only need one more to be complete. It is nice to know that no gunk can get in those rca connections, and the slight hum I still have in my system was reduced about 50%, so I considered that a bonus. Maybe the last set will make a difference. I'll post back here when I get them. I just ordered them, and expect them in about 5 days. I know that if I took the say... $150 total cost of 4 sets that I could probably get something that makes a more obvious difference, but purchasing them one set at a time, I hardly notice the expenditure. That Musical Fidelity amp is a class piece. Treat it to a nice, new, shiny new cap.
