Someone did a performance analysis of it a few year ago, and here are his conclusions:

“3. From a sound quality perspective, I don’t think you could go wrong with any of the “sinc” resamplers and DSD modulators I tested out. While I remain agnostic around which DSD/sigma-delta modulator is “best”, I accept that people can have subjective opinions on this since there are real differences in distortion and noise levels between the different settings. Perhaps certain settings could lead to more “euphonic” output depending on one’s gear. But I believe sonic differences would be at best subtle though based on my own listening and what the results tell me.”
