Melbguy1, I believe sabai is sharring his exsperience with IEC's, which BTW are made different than the recepticles, The GTX-D as you said is pure copper at the base metal, then plated with Rhodium or gold, David, to mass the confussion more, I researched these recepticles more on audiogon past threads of the GTX-D recepticles, there seemed to be alot of members that had gold and went to Rhodium with satisfying results, However, the ones that did had tube equipment, to bad we cannot rent these things like cables and find whats best for our paticular systems, that would be great wouldnt it david?
