My F-1X rarely leaves the home rack, where it's paired with half of a Mackie M1400i, which I purchased because it was cheap.
If I do take the F-1X out of the house, it's paired with some lightweight class D power amp, I can't remember what kind, I haven't opened that road case since I moved 5 years ago. Usually I use a Carvin class D head.
For the gigs I do, no one is listening to my tone close enough to care all that much.
