I used the Audience AU24 speaker cables, (bi-wired) for my Revel Studio speakers, (the Salon's little brother), and always thought they were very good, especially for the price. (I paid about $400, used, for each of my two 2-meter pairs).
My two cents worth.
Good luck in your search for, (your friend's), speaker wire.
