My Marantz PM-KI-Pearl came with a full set of these plugs for use on any open/unused IC connections. I have not done a comparison yet to see if they make an actual audible difference, but from what I've read they are supposed to help lower the noise floor a bit. They are installed.
Are these plugs of more benefit to entry-level high-end gear or does it also make a difference with SOTA equipment?
I'd love to hear your thoughts on this.
