So I got caught up in the general view on this thread that the NiceHCK Black Cat cables were very good value at their discounted prices, which totalled for a 4.4mm MMCX and two 4.4mm .78mm, 2 pins, at under £50 for the three (the two pins were more expensive than the MMCX). They are good strong, well made, cables.....BUT what the F does NiceHCK BlackCat Zinc Copper Alloy Oil Soaked mean. Even if whatever is true, are they soaking it in oil like a 'Confit' duck leg. Zinc/Copper alloy for a cable...anyone heard of that before? They are well made and work well BUT why oil soak?
Zinc-copper.alloys, aka brass are hardly known for the use in wires/cables.
Two main reasons for this is 1) alloy resistivities are significantly higher/inferior (as high as 4-5 times of that of pure copper); 2) brass is much more prone to corrosion degradation compared to copper.
So two reasons for using Zn-Cu that I can possibly think of:
I..Zn-Cu look gold-like. But then they still corrode, so the black shearth was used, and no golden anymore, with the metal appearance being irrelevant.
2. NiceHCK making a pun of audiophiles, first starting with "lantanide" alloys, then this brass, not much different from those "proverbial hangcoater wires"....
Then "oil soaking" is quite legitimate, which may come as a surprise to many.
This treatment was scientifically developed to improve corrosion resistance by precluding oxygen from geting in contact and oxidizing the wires. In UK, they even used mineral oil to protect some underground cables (brought quite a bit of problems in a long run, but still there...)
"Black cat" clearly shows that with the nice looking connectors, audiophiles can buy just about anything inside (and no need to pay for palladium even)- the beauity is skin-deep clearly.
These all the arguments above will bring my main point that if $25-75 cables will be sold as nice jewelry - with well designed comnectors, nice looking connectors/plugs, beautiful patterns of the cable insulation, including personaly artistic and national/cultural designs, and finally nice comfortable fit, accomodating different prefernces - everyone can benefit greatly
(I will happily get more on top of my 75+ cables)
