I forgot to mention I used some modelling amps before, a few of them I'm still using (Peavey Vypyr, Line 6), but I think it's not the real thing.
The nutube approach I think, will not be not the same as real tubes because lower gain per stage and lower anode voltage. You could also use one normal tube with lets say 50-60V anode voltage. Gain will be lower then automatically. So I do not see much advantage for the nutube beside power dissipation and dimensions (volume).
