I am wondering about AC plugs myself. My question is the interaction of differing material? So a Furutech gold plated GTX.. Do I 'need' to use a gold plated plug? (Currently I have two Wattgate copper unplated plugs in the gold plated wall GTX. I am buying a silver plated Wattgate since the wire I am using is also silver plated copper.I wonder about the galvanic corrosion? between dissimilar metals in contact inside the connection? (apparently this is NOT a problem, since no one writes about it in this context.) (An aside.. Adding a wrap of teflon pumbers' tape around the base of each plug blade then squeezing it down to 1/3 height, SEALS the plug to the duplex. keeping fresh air out and lessening oxidation of copper and silver metal parts)
I was interested in the Oyaide Pallidum 9.3x 10^6 /platinum 9.4X10^6 plug until I see it has much less of the conductivity of Silver 6.3x 10^7 (copper is 5.98X10^7 very close behind silver)Rhodium is 2.23x10^7 BTWAfter years of using cheap duplex, I just have gone 'all in' in high end duplex.. The most interesting thing to my mind full of economic stuff is the cost of high end duplex. Compared to cables, which can range from a few dollars to $multiple tens of thousands per meter pair! ditto speaker cables and powercords. duplex are NOT expensive. The best cost less than $300. Which is only the price of a moderate cost pair of IC. Though if you add in carbon fiber covers.. can double the cost. But STILL dirt cheap in the grand scheme of uber $$$$ wire stuff. So for high end audio, the one place where high end money driven madness has NOT struck is duplex outlets. So with all that in mind I jumped in and bought a dozen Furutech duplex. 7 gold, 5 Rhodium, Planning mass burn in, daisy chaining them all front to back... for a month.(note I am not fussing about trying every outlet from Tesla to Blue whatever.)
For the cost of two pair of the sort of IC I am now using, I can have every important outlet in my system/conditioners and such high end duplex. Plus the Furutech GTX gold is on sale as low as $108. once 'in the basket' at a reputable dealer! ... the GTX DRhodium NCF is down 15% off.
