I've got the SEi version. It was upgraded by Gary from the original. The difference in the sound is as Gary states: it's warmer and even more natural-sounding. After listening for a while my feeling was that the cap upgrades got the sound closer to what I hear from vinyl playback. Not as good but definitely in the same neighborhood. An absolutely worthwhile upgrade. Gary doesn't disappoint. No drama, no nonsense. Just great service and honesty.
