Cardas Machined RCA Caps.???


I have seen many ads about the benefits of using these caps to avoid noise on the non-used RCA inputs...Somebody even posted an anouncement today at Audiogon.
Has someone ever tried these caps? Is it really beneficial and acoustically audible?
What do you think?

I haven't noticed any sonic differences. I purchased them mostly to keep dust out. They are easy on the eyes as well.
One needs to be careful constructing shorting plugs. Some preamps get very unhappy when shorted. As mentioned earier... the Cardas Caps are "non-shorting." Be sure to check out the XLRs as well. They are another fine product by Cardas.

Someone wrote in the AA forum that you can test your system by putting Al foil caps on your un-used inputs / output.

If you notice a difference you can decide if you want to spend the money for nice looking caps.

I started with these when I was experiencing a problem with my phone pre amp. They may have cut down on the RF noise but I won't swear to it. I will say that the other two benefits are (one) no dust can get in the jack and (two) they look so cool! Small investment and decent returns, it's a tweak, tweaks are more than not, a waste of money, but fun.
