The first clip is Axe then amp. The second clip is amp then axe. Or maybe it's the other way 'round
In the "Questioning" thread I posted the waveform of the Axe-Fx followed by the real amp. I then posted the clip for that waveform. Do you hear a difference?

Here's the same clip but with the parts reversed:

I think it's the other way round. The first part in the first clip sounds more dynamic and natural. The second seems to have less dynamic range with a slightly muddier low end. The first part also has better blended early reflections, which makes me think it's miked. If I'm wrong, then bravo!
The second half of the first clip is crisper and clearer to my ears. Ten years ago, in the days of the Boss GT-8, I would have said this was due to odd number harmonics caused by transistorised clipping. With the sound clarity that has come with recent software released I would not know which is which. Whether I like it more of less depends on context. The crisper sound might stand out better in a mix, or it might grate on my ears.
This best sums up my experience. There may be a small difference but maybe a slight turn of the knob could minimize that even further. Nothing to agonize over, at least for me.It seems like an auditory illusion to me. When I listen to them consecutively the first clip sounds better to me; more clarity, more open, and less compressed then the second clip. However, if I jump back and forth to the same spot in each clip they sound the same to me. I believe it may be because the clips seem to end on higher frequencies than they start, so the beginning of the second clip appears to sound a little duller and more compressed when compared to the end of the first clip. But, when I jump back and forth to when they should be playing the same frequencies they sound the same to me.
Could even be all Triaxis or all Axe-fx....
As soon as you ask if people can hear a difference, a lot probably will.
It's the way our brain works. As soon as you get a piece of information, your brain processes it and clouds your judgement.
