Hi Kenzo,
For what its worth with regards to driving SF Strads I read on another forum, can't recall which one, about a guy going double D-Premiers (some 500 W on tap) and his comments was in the 'match in heaven' and 'never heard better'.
I myself is on the hunt for new speaker and auditioned SF Guarneri Evo and Amati Futura (However I really would like monitors). At the time I used my D200 which didn't master the G Evo (strange and forced mid range) but did it almost perfect with A Futura which I believe is less sensitive than the Stads. A Futura sounded more monitor than the G Evo but that is another story. Amati is on my list for next speakers.
Conclusion, a D400 would have driven the Amatis perfect and your Strads should, no doubt, sing perfect with D400.
