All of Sonic Frontiers present pre-amps, ie the Line 1,2 and 3 are fully balanced. The new SE versions would also be fully balanced. But you're right, you have to specifically ask a knowledgeable rep., or see literature, of the product to know for sure.
BTW, not everyone agrees that fully balanced operation sounds best-- this is an area of contention, and their have been many threads discussing the subject. I don't use XLR, but then I haven't given it a fair trial either. Sonic Frontiers and Madrigal both strongly recommend balanced. Good Luck. Craig.
