The Morrow cables all use solid-core conductors (which is very good), but they are all silver-plated. If the sound turns out to be too bright with too much upper mids/highs push (after 200 hours burn-in of course), then I would go with some of the Audioquest interconnects that do not have silver-plated connectors, such as the Big Sur series. These use really nice copper solid-core conductors.
