Hi Bullitt,
Like david_ten, wondering what specific sound qualities you noted in this comparison.
Also, when you listened in the corrected vs. uncorrected comparison, did you change your speaker position?
A bit surprised you were reluctant to post--I think most of us really enjoy reading what others enjoy with their DI's. Oh, there have been a few cranky posts but far far more civil and helpful ones.
Thanks for posting and look forward to a few more details.
