Simaudio I3 SE..... anyone have one?

I have seen so many reviews on the I3 but nothing on the I3SE. I was wondering what people thought on the differences between the two or the I5. I have both the Dynaudio C1's as well as the focus 140's and listen to mostly rock, acoustical and jazz. Thanks!
I talked to adriene from sim having an i3,thought of having it upgraded.said definate differance in power transformer as well as some circutry,but not quite the i5?that leads me to believe that the i5 is way to go.Having just bought the i5.3 player i5.3 amp is my next upgrade.The i3 itself played my dyn 52,s and 1.3se,s beautifully.I listen to mainly jazz.
