Newbie question, what are Litz cables???? i know OFC is oxygen-free copper... perhaps the copper is vacummed and the cable hot plastic injected in the copper wires during vacuum?
I see on sony specs that they say OFC-Litz.... i think also says so on the XBA-H3 user manual
EDIT: REading the manual of my XBA-H3's it says both cables are OFC-Litz, and the supertweeter diaphragm is made of aluminum
A quick google search (since I was interested too):
The term litz wire is derived from the German word litzendraht meaning woven wire. Generally defined, it is a wire constructed of individually film insulated wires bunched or braided together in a uniform pattern of twists and length of lays.
