Count me with the Sain Line fans. I do also use the Synergistic Red fuses in my ARC ref6/ref75se combo, but the Sain Line cords are a more noticeable improvement. I did not really get a boost from the fuses, but YMMV. I have tried some other cables, but the Sain cables don't really change the frequency balance like some others, they just reinforce the natural ARC sound.
