Why the SIVERY spades on new HOLOGRAM?

Hi,fellow Acoustic Zen users:
Has any one of you noticed that the newest version of
Hologram II cable have the "SILVERY"(silver?)spades
other than the "GOLDEN"(copper?) ones they used to have
AZ said they have dropped the "golden" spades for good,
there must be some benefit to the change,right?
Who can tell?
its 'back to the future'. the gold finish was added to audio equipment in the late seventies and has been with us ever since. pleasant to the eye, it has never been sonically different than the old silvery finish.
