I had Gallo 3.1s and finally sold them. I didn't have the bass amp, so cannot comment on that feature. I did however experiment with the 15 Ohm resistors tweek found here http://www.10audio.com/gallo_ref3-1.htm.
I didn't like the 3.1s because to sound their best the volume had to be quite high; at lower volumes there was no bass and the speakers sounded flat. I drove these with a butler 2250 that carried the current these speakers supposedly liked.
I have heard the 3.5s are a much better choice. The base is better and the top is the Strada 2, an improvement over the 3.1. I have-not heard the 3.5s, but have heard the Strada 2 with sub - which is basically a dismantled 3.5. I thought it was quite good and per Gallo the 3.5 was better integrated.
