I would go with Option 2, I have used that configuration many times with various MF products. I have two MF systems and also currently have A3 integrated.
Although it is true you want best signal to go to tweeters, your bass also needs much more power and the 3.2 amp is significantly more powerful vs A3 integrated. MF specically designs integrateds to used as you describe in option 2.
Sunnyboy makes some good points that ideally you would get bigger better integrated by MF or preamp/amp set, but option 2 will improve upon the sound of using A3 integrated by itself.
The new MF 308 integrated sure looks nice, or you could eventuall get A3.2 preamp to go with A3.2 amp......many options with MF gear.
