One idea I had for diy making similar cables or products is to coat the metal in the end plugs with some carbon nano liquid and then use a Telos QBT cable run-in machine. Basically this machine runs such high voltages into the cable that the metal liquifies (using my own words) and then solidifies again. But if you put nano liquid on the conductors then perhaps some of this carbon based superconductor liquid will “absorb” into the metal conductors. Repeat the process over and over for greater absorption. Try different nano liquids with different compositions, like silver, for different effects. Not sure if this would work, but it might be possible. For greater effect coat the entire conductor in a nano liquid, then electroplastic it with such a machine. I read that synergistic research uses a Telos QBT machine, but I cannot confirm this. Who knows, maybe it could work. It would be worth a try.
Interesting thoughts! Some years ago a company released a hi-fi specific contact enhancer that I bought and tried. I was frankly stunned by the results. The uplift in clarity was something I’d never heard before, so all the hi-fi related parameters as well as naturalness were radically enhanced. The stuff was extremely expensive, but the effects it brought were more than worth the cost of entry, based on the audiophile value scale where sound improvement has a monetary worth.
The stuff had a peculiar, very pleasant ‘scent’ and was highly volatile, so given my access to some very sophisticated analytical instrumentation, I ran a small aliquot through a GC-Mass Spectrometer. Turned out the stuff was a Fluoro-carbon, basically a fluorinated hydrocarbon similar to ‘Freon’ with a little Lemonene to provide the smell. The scent of Lemonene is also known to be very relaxing and ‘euphoria producing‘, in a mood rather than psychotropic drug way (The same way certain light wavelengths and essential oils can modify mood).
So I bought 250ml of analytical grade solvent for about 1/50th of the price and cleaned my system. The difference it made was transformational.
So, given what we know about taking complete plugs and cables and transforming their sonics without dissassembly or anything destructive like heat that would damage delicate materials, the treatment is something that is external and fairly benign. The manufacturer talks about Quantum effects and indeed the company had Quantum in its name, so I would assume that part is genuine. There’s a lot of Quantum stuff that’s really just everyday electromagnetism. The treatment isn’t patented, so there’s a good chance it’s based on already known effects, just not previously applied in the audio sphere. So some kind of surface treatment, coupled with some adjustments at the electro-magnetic atomic structure would fit the bill nicely.
I‘m afraid I don‘t buy the part about liquifying metal as that would require a lot of energy that would affect the less robust parts of cable and plug structures, but a technique to modify the surface conductivity of the cables and plugs is certainly very feasible.
QSA fuses are another good subject for study. They appear to be unchanged from regular cheap-as-chips fuses, yet have the ability to transform the sound produced by a hi-fi. I have already demonstrated that simply cleaning a fuse’s end caps with nothing more than a highly effective, low residue solvent can bring monumental changes, so I tend to favour the concept of surface treatment combined with some sort of electro-magnetic conditioning. A deep clean, followed by surface conductivity enhancement and some form of electromagnetic conditioning would for sure make a very large, even profound difference to how a cable or plug sounds.
