I have not yet read anything good about nickel being a good conductor. They main reason it is used is to prevent corrosion. "Buyer beware", if you decide to purchase a nickel product, I am sure every one would be curious to here what you think. You should look into companies that offer 30 trials, then you could test it on your system.
Is nickel any good 4 speaker cable or power cords?
There is a brand call Canary Audio they use nickel plated copper for their power cord. I heard that nickel is no good for audio because of their low conductivity, but don't they carry more current than silver or copper? Is nickel a good material for audio stuffs? I am not quite familiar with metallugy but info would be appreciated =) Thanks
