I took a look out of sheer curiosity.
"... it transforms ordinary materials into superconductors, ensuring flawless electron flow, heightened conductivity and a sonic purity..." - that triggers alarm in my head right away (I have MS in EE).
You cannot transform ordinary metals into superconductors unless you lower surrounding temperature to a quite low levels.
The most conductive metals are silver, copper and gold, respectfully.
True, metal conductivity can be improved a bit using very special treatment. The question is - do we really need to?
Let's talk about power cable. 12-gauge wire resistance is 0.01588 Ohms per 10 foot. Accordingly to the law, 10-foot round trip with a 5-amp load (that is 120V x 5A = 600 Watts) has a voltage drop of approximately 0.16 Volts. Assume your magic tecnlogogy gives a 100% of improvement. That is 0.08 Volts loss. Do a math, convert it to power. Does it really makes a difference on your AUDIO signal? If you think "yes" - go and buy that amazing cable.
"QSA, a proprietary marvel born from 22 years of intensive research and 4 years of rigorous testing... QSA technology remains a closely guarded secret" - wonderful. I am not asking for secrets. Why do not provide your "rigorous testing" results and show exacly what is impvoved?
Truly, I never saw ANY testing/comparison result from any magic cable maker. Please show me, if you find any.
Again, if you are confident that magic works - go for it.
