Found this amusing:
Was reading about protective "XLR Caps" product manufactured by Vincent Audio.
Are their claims true?
So my several un-used XLR connections will potentially compromise performance of my AV pre-pro?
Description from Audio Advisor catalog listing (quote):
"Safeguard Your Unused XLR Inputs
The rear panel of an AV component is literally a backdoor for airborne EMI and RFI noise. These kinds of interference can sneak into your AV system through open, unused XLR inputs on your components, compromising performance. And unused XLR inputs are also susceptible to incursions by dirt and dust. And who wants to plug your gear into a dirty connection?
They Protect Without Shorting
So what’s the solution? Vincent Audio’s High-end Connection Caps fit over unused XLR inputs. Unlike traditional shorting plugs, these caps do not short the inputs, and many components don’t like shorted inputs. These durable, high-quality caps are made of gold-plated brass with a Teflon inlay.
XLR Connection Caps come two to a box, and oh, what a box it is. The attractive latching presentation case is practically worth the price all on its own.
Choose Female XLR Caps to protect male connections. Choose Male XLR Caps to protect female connections."
