I got a chance to play through a buddy's SF amps last weekend: a twin and a super, both with upgraded tubes, SS rectifiers, and better speakers. The twin is still a clean machine, and the overdrive is a bit fizzy, but the cleans are stunning. The super, on the other hand, had slightly warmer cleans (though still bright and defined) and a much more pleasant and early breakup, subtle at first and growing evenly as the amp was turned up. I'd take the super any day over the twin, which I found too bottom heavy and slightly sharp in the cleans, and fizzy when pushed. It's a great amp, but the super definitely eats it's lunch.
