I have a Saturn + the Rega DAC. I performed extensive A/B comparisons of the Saturn through the Rega DAC against the pure Saturn into my LFD amp and Harbeth Compact 7's. In every instance, the pure Saturn came out ahead. Before buying the Saturn, I was planning to use a Music Hall CD 25.2 through the Rega DAC for CD playing but experienced a lot of jitter issues. So now I am quite satisfied with the Saturn for CD's and the Rega DAC for all the computer based music.
Given my experience, I would say that all the opinions that an Apollo + Rega DAC are better than the Saturn are inaccurate and probably more speculative than actual testing based.
