grover huffman cables

Does anyone have info regarding these cables, Are they silver copper any listening experience with them. thanks for any help
Old thread but the current Grover Huffman cables are copper, silver and aluminum.
What the aluminum does in there I don't know. The price of admission is very reasonable so I might give the ICs a try.
the aluminum came about when grover listened to some jps labs cables which use an aluminum alloy in there cables and he liked what he heard.

One additional bonus item to shout about. Grover is a great person to deal with. He replaced a broken speaker cable pin connector by sending me the newer version of the same cable!

I was jolted by the experience.
