Will not really work as there's no poweramp emulation in 11R.
So adding the Triaxis preamp in front of whatever amp will cascade 2 preamps, will no sound good or at least will not sound better.
Years ago, a friend of mine tried my 11R connected to my tube preamp into 4x12" Celestion G12K100 cab and he said it sounded totally insane. He used to have a Triaxis
