Default Re: Connectors made from exotic materials.

Audio is full of snake oil for sure, and cables being a particularly fertile ground for this.

But you have to be a bit careful about saying that rf ingress has no impact on audio.

One particularly audible example is the zzt-zzt... sound from your speakers when your mobile phone does a station seek.

Now sure the RF level in those circumstances is pretty high, but nevertheless that is 800MHz or thereabout being picked up in cables and then demodulated by semiconductor junctions in the audio amp.

There are other examples, but that is the most obvious and immediately audible. Even the BBC is not immune to this, with the characteristic sound from an interviewee's mobile phone in a R4 studio on occasion.
