Power Cord for Accuphase Amplifier

"Please keep in mind, after you scratch contact surface, contact resistance could dramatically  increase, and then plugging “new fancy” cord will give you relief for few days.. then you need to try to “improve” sound again, by buying new PC :-) "

- maybe in micro circuits, chips and tiny components, but in IEC plugs & receptacles, I don't buy it ... 

Cheap chinese rubber power cords with molded plugs don’t scratch IEC connectors. But the good wattgate and furutech gold plated plugs do. And who inspects IEC connectors in their components under  the microscope? 

@audiophile1 "And who inspects IEC connectors in their components under  the microscope? “ ppl who care about value of their gears? 

I guess I do not value my gear or anything else I have at all, simply because I don’t own a microscope. I use high quality power cords. I do not use hospital grade outlets as they strip the plating off the connectors on the power cords. The connectors I use are either gold or rhodium plated and they’re polished smooth to avoid scratching IEC.
Stop using cheap chinese power cords and you won’t need a microscope 

@audphile1 "I use high quality power cords” 

understand! the problem with “high quality cords” is a different understanding of key performance and reliability metrics. for example extreme high contact pressure and the same time small effective contact area plug will cut through noble tin (few um) plating layer, thus exposing contact base metal for oxidation. reputable interconnect manufacturer checks contact integrity after series of plug/unplug iterations (x100 times), which helps valued gear to work longer time at the same performance level. “scratched” IEC plug can cause short time phenomena of “hearable” PC replacement SQ improvement, and which is unique to each case. 

ideally IEC receptacle should be replaced together with PC using the same brand/design/series plug, latest rhodium plated contacts are very good to consider, specially for aged gear!

Got it. Thanks!
