I’ve used Acoustic Zen Satori shotgun biwires in my system forever. Very neutral and natural sounding with great tone, detail, and soundstage. Had some others come through the door but the Zens always stay in the end. Easy to sell if they don’t work for you.
That said, I like @millercarbon recommendation above and would strongly consider that as well.
