Capping unused rca & xlr connectors???


What is this supposed to accomplish? Probably subjective but is it snake oil or does it provide quantifiable benefits?

Thanks

It is customary to short any unused RCA inputs on preamps. This prevents pops and clicks when switching your source selector between actual sources that are plugged in. Also prevents unused inputs picking up stray RFI. You can use pre-made shorting plugs or make them yourself. I don't recommend the Cardas caps because they don't actually short the input, but only shield the hot signal socket from RFI.

Unused XLR inputs do not require this treatment since they are balanced and self-cancel any noise.

You said that you don't recommend the Cardas Caps....what
pieces do you like for this purpose?
