Hey everyone! Sorry it took me so long to record a clip with the rectifier running through the same impulse as the axe fx model.
Here it is:

I used the slave out feed from the recto plugged to input 1 left (rear), and bypassed all blocks in the patch except for the cabinet (which is the same one used in the video).
The first one is the axe fx II, the second one is the real rectifier, which sounds a lot thinner now. I'm guessing that the speaker resonance simulation on the amp block gives the model more body (Mikko, please correct me if I'm wrong!). The model also sounds smoother to me.
I think that in this case, using the same IR, the Axe Fx wins. I'll try to do the same comparison this weekend, but this time I'll plug the axe fx to the rectifier's power amp and mic both of them up using the same mic position. This should also be interesting.
