Effective 1 August 2015 we switched to 115V wall plug with Rhodium plated contacts, matching the Rhodium plated contacts on our IEC plug, both precision-manufactured in Japan. Rhodium plated contacts are a top to bottom sonic upgrade with absolutely no down side. We can not explain it, but we are convinced the Rhodium plating caused lower audible distortion and increased listening pleasure. I now happily invite direct comparison to mains power cables up to $1k MSRP and up.
Schuko plugs with Rhodium plated contacts appear to be available for moderate cost, and we shall employ only such type for our 230V clients.
We invite owners of our earlier mains power cables to return for plugs with Rhodium plating, a good value upgrade for $15 per plug + return shipping.
One month trail with full refund minus shipping for all standard terminations. All sales final for custom terminations (noted in product descriptions below). Returns require client to contact vendor for RA #, pack properly, insure for full original value, and pay only return shipping and insurance fee.
We generally recommend matching the metal plating of all connector contacts for analog signals. Mismatched plating contacts increases potential for electrolysis. We heard mismatched contact plating solely and directly cause audible hash and grunge. (We corrected the error in this case by making special adapters to match contact plating on both sides.)
We can not more strongly recommend annual application of Caig DeOxit Gold contact cleaner and treatment on all accessible contacts including AC mains plugs, IEC, and duplex outlets.
All products below are neutral, transparent, and suitable for wide array of systems because they lack the ubiquitous tendency to act as a system EQ.
