Just talked to a friend about the Pure Cabinet feature and he told me that Axe (which he's using) has a new beta firmware as well addressing the very same topic.
The description is rather short:
Added “Dephase” control to Cabinet block. This parameter controls a sophisticated process that removes the “phasiness” from IRs and can yield a more “in the room” experience. Note that the processing required is extreme and the control can have some lag and this will also add slightly to preset change time.
Interesting that the 2 firmware versions show up at the same time...
