RCA Caps


Is anyone using RCA caps (plugs) on their unused audio connectors?

I'm considering going with either Telos or Cardas.

I like the idea of keeping dust out of these while benefitting from EFI/RFI rejection.

I have been using the Cardas for years. I wish I could afford them for the S-Video and all my XLR ins/outs that are unused, but as you have seen they are not cheap. For the SE caps there is a brans out there that has a little knob on them, if you can I would get those as the Cardas caps can be a pain to get off on SE jacks that are close.
I purchased the generic RCA Caps from Parts Express. I can't tell the difference between them or the Cardas ones visually. I've put them on varying pieces of equipment in my mostly mid-fi solid state systems and I haven't heard a difference either way with them in place. I've put them on preamps, CD players, integrateds even on a subwoofer amp and I could hear no difference. I agree with Theo to look at the caps with the little knobs on them. The generic caps I have can be hard to remove if your RCA jacks are in a tight space.
I bought a set of 10 pair of caps from Vintage Audio Lab off of eBay for about $20 shipped. Not really sure I can tell a difference, but better safe than sorry. Especially since it was only $20.
