I got a DA sprocket and it's still pretty noisy. Sharp teeth shoulders that need to wear in. The Surly cogs are much smoother. EAI swankypants one is machined with perfectly smooth shoulders, and a titanium nitride coating. That coupled with the KMC swankypants ti nitride chain would make it whisper quiet.
