Cardas Caps on unused digital jacks?


I have used them on all of my unused analog RCA jacks. I have one pair of unused XLR jacks that I plan to buy Cardas Caps to cover.
But what about the digital jacks. I have not used caps on any of them. Should I be covering them too? How about the unused "video" jacks (all kinds) on the digital transport. It is the EAD t-7000 so it also plays LD's, which I don't do. The EAD drives my D to A via AT&T glass.

Opinions are appreciated.

I cover everything with those nifty little dudes. I tape three of them together for my unused balanced ports :)
They were a little tight when installing on some of my gear. When I finally took them out, the tighter ones left surface scratches on the jacks.

So if you have the urge to buy some, make sure you expand the caps to prevent scratching your jacks.
If it's all or mostly about keeping the jacks clean...why not use those soft-plastic thread-protector tips every hardware store sells for about 8ยข apiece?
Cardas caps are to prevent EMI/RFI intereference to enter the chassis thought the so called "darn little holes" in the middle of the RCA jacks. I used a total of 46 in my system and some equippment might not sound as good if you use some, and of cause some do. If I have to use them to cover ALL the RCAs I will br broke... do some blnd test to see if they help, then use... Also, they can be also as long as it's a RCA jack.
