XLR & RCA caps

I don't hear any sonic benefit from using these but I think its a good idea to keep things covered as exposed connections will oxidize over time.

I agree. I use Audio Additives caps from MusicDirect

I have a lot of stuff. I bought 100 caps from a nice seller in Taiwan (who since has vanished from eBay?)
I have to say the addition of over fifty caps to the backs of all my stuff did result in a tiny improvement as a 'blacker background'
The most visible improvement was on my plasma TV, which i added caps to all the unused inputs with RCA connectors.
Audio and video. And on all the unused DVD player connectors.
The screen definitely gained a smoother appearance. less noise/grain.
I wanted to buy some of the XLR caps from that seller, but discover he is gone.
So yeah, i am happy i bought the covers.
I also use power conditioners. The main one a Furman REF 20i and Pangea power cords.
Other things which improve grain and stuff.

Agree with the above. I have used the Cardas RCA and XLR caps for years, (ever since they have been available).

Agree as well. I use Cardas rca and xlr caps. Can't say I hear a difference but like the fact that dust does not get in these openings of my pre and cdp. This is a tweak to buy when you are in the mood to tweak, don't want to spend alot or be disappointed if the tweak does not improve your sound.

I have the cardas caps on rca females on my pre-amps; no change in sound I can detect
