I hate to thread hi-jack, but let me ask a quesiton. I'm going to go ahead and say the AD/DA converter in unit makes the biggest difference in the reamp you did, correct?
I did a comparison of direct to amp and a reamp with the firepod and there is barely a hint of difference, where in your case the AD/DA of the two units (firepod and profire) sound completely different... this seems kind of strange.
Sure you didn't leave an eq on for something similar on one of the clips? I'm not protecting my firebox, because your little shootout almost made me toss mine out the window- but after my own test, I'm still standing by my presonus stuff.

Again, beyond dead, I don't mean to hi-jack since you inspired me to do this shootout in the first place.
