What are small gold colored "caps" that came in bag with perfect path products?


I recently upgraded my Pre/amp/CD player and cables so I'm just now getting around to evaluating some perfect path products I bought.  In the bag with alpha e cards and thing you plug into outlets are several small gold colored objects looks like a cap to something, but it is not obvious what.  Anyone know what these are ?

Thanks for your time.

"....In other words the CD player is connected to the system, but not selected, and yet listening to the turntable the sound was better with these things on the CDP!...."

How can you put the caps on the CD player output if it's connected to the system? 

Because for like 20 years now they all have lots of extra plugs for surrounds and crap. You can see both the grounding and the cover type here in image 9, they're alongside the modded RCA outs that are connected in this photo.

Technically of course even with the interconnect disconnected the player is connected to the system as long as the power cord is plugged in. That's the way components work with power, neutral comes back to the conditioner, same conditioner everything is plugged into, everything is connected together. Same reason doing something on the panel or anywhere in the house affects the system. So its nowhere near as mysterious as I let on. That was just my usual trigger trolling. Usually catch at least a few bottom feeders, thought I had one but no, your question is legit. Oh well. Its a numbers game. 

Thanks for the opportunity to link to my system yet again. Eventually someone is bound to notice hey, that millercarbon guy he has a system, but the guy who posts 5x as often doesn't? ??? Never know. Could happen.

That's true for receivers but NOT true for CD players.
Just cover the open RCA jacks with copper foil. Also, is anyone suggesting something other than RFI/EMI rejection is going on here? For example, if the caps are used to cover unused RCA jacks on unplugged components.
