Just spoke with John Schafer from Wadia, He has this to say. Significant improvement over the 581SE. It has better all around dynamics, but more importantly better image deliniation from quieter sapces (darker some may say, but not correct if there's info going on arong performers, instruments etc.) It picks up the micro dynamics so well that it gives the information of what's happening around the images (if the recording is up to it. Most aren't even close)Pace is improved. It is overal more involving.It's advanced technology over the 581. I'm swapping into one after I sell my 581SE.
