I received my SEG back from Stan with the Supercap upgrade and found the sound quality, out of the box dull and lifeless. It took about five days to really sound better but it was worth the wait. Bass noted are not deeper but there is more bite or attack to the presentation. Greater sense of 'being there'. A nice improvement.
