OP - I too am running Totem Forest Signatures and using Audio Envy's SP14 ribbon speaker cables made with OCC copper and an active ground. Good luck in your search.

Speaker cables with good timbre
As the title says, i would like to hear recommendations on a pair of speaker cables, copper, that have a very good midrange, imaging and truth of timbre or faithful reproduction of instrument sound. As i get older i started to realize i value those characteristics the most when i listen to recorded music. Thank you in advance.
