Poweramps used by Fractal Audio for testing - which ones are they?

[GreatGreen]

Presumably Fractal Audio tests the accuracy of its models against real amps in multiple scenarios, including with IRs + FRFR monitors, as well as straight into a poweramp and guitar cab for amp and cab in the room scenarios.

Anybody know what kind of amps are used in these cases?

This isn't to say that Fractal uses either of these, but Cliff has recommended Matrix and Fryette before:
