Any speculation on what QSA is doing with their fuses? Not that it really matters - as long as they sound great...but Graphene - perhaps? I mean SR, PPT and myriads of others are using it...there is certainly something going on here - I can hear the improvement when applied properly.
From a Science article...substance perhaps?
One of the biggest finds is that, using Weyl fermions, the researchers will be able to create fast-moving electrons with no risk of backscattering, or loss of electrons in a collision. Backscattering makes electronics less efficient and creates heat. Weyl electrons are able to avoid collisions and eliminate backscattering.
Essentially, what this means is that the Weyl fermions could provide a better flow of electricity and assist in the creation of more powerful and efficient electronics, especially in computers.
It's interesting as others have found purity of copper sounds better - and they have suggested that the improved lattice structure helps with flow...and sounds better...perhaps graphene.
I am auditioning some new "gear" / "Tweaks" right now. But when this trial has passed, I will move on to these fuses and outlets...
