just a quick note to say that the 183-3 actually does a perfect job
bringing a single line out of the fa-101 up to the a-100's level --
the reason i was thinking i needed to modify it to bring up the levels 
was that i was using both inputs, which seems to cut the level in half,
perhaps because a circuit is being completed inside the 101?
not sure, but that's what happens.

at any rate, since those two inputs are actually just a 2-fold multiple, 
i can combine the signals internally to my computer with virtual patchcords
rather than with real wires in the physical world.

with a single input, the level seems to need to be at around 7 at 4x amplification, 
meaning there is actually still plenty of headroom in case i need to be more
heavy-handed or actually want to induce clipping for whatever reason. 

i imagine this would be the case for a number of other audio interfaces
as i was looking through the specs & both the edirol & the fireface have +4dBu outputs,
so this is probably the same for both, as well as other interfaces with +4dbU outs.

best,
mark
