Rogue Audio's owner recommended Darwin ICs to a reviewer which led me to buy three sets and I couldn't be happier. After the first two sets I moved up to his higher end line for my SACD player and there was a noticeable improvement. His basic line is no slouch either. I don't know if he's found better but chances are it'd be a sideways move, depending on your other gear.
All the best,
Nonoise
