Shorting plugs

I had my spare RCA sockets on the preamp shorted and thought that I didn’t need to worry about the XLR and AES/EBU connections.Wrong assumption! Shorting the latter resulted in a significant reduction of hash and increased clarity in the treble as well as more precise positioning in the sound stage. Everything matters and as tweaks go this one is value for money.

As I am only shorting inputs the warning on shorting RCA outputs is certainly apposite, thanks to all

@antigrunge2 and all

What do shorting plugs do and why should I try them?

Thanks

They are shorting the positive and negative poles on unused inputs thereby preventing EMI/RFI incursion into circuits

They don't objectively do anything but drain your wallet.

A bit of a know-it-all without personal experience, are we?
