Hi Simao,
Just because you "can", doesn't meant that you "should".
The Titus has a very high frequency crossover, and is also very easy to drive, so IMO bi-amping would be wasting most of what you can gain from the Sophia's presence to give you an incredible mid-range.
Alternately use your second set of speaker wires to set up a line-level feed to active sub with crossover of 55-60 Hz.
Or, bi-WIRING (not bi-amping!) is good to try, where you run two sets of speaker wires from the Sophia output terminals, with one set going to the high-freq posts and the second set connecting with the low-freq posts (jumpers removed).
If single-wired to speakers, try replacing the stock jumpers with connectors similar in grade to your speaker wire.
Good luck with your Sophia, and please let us know how it all comes together.
