i doubt one could detect the difference between pure gold and pure copper, assuming connectors and all other materials were the same.
This is exactly the case with Jade Audio cables. JD uses the same manufacturing process in all his models for insulating the lines, wrapping them in the jacket and terminating to the connectors. Provided the listener compares all Jade models with the premium connector as standard on the Hybrid, the only difference between the Gold, Vermeil and Hybrid models is the wire material itself. And the sonic differences between these 3 models is significant in frequency extreme levels AND portrayal of space.
Mr Tennis, before you doubt any more what many of us have experienced with this product line, contact JD to hear these differences for yourself.
