Sansui AU-7700 into contour 1.3 ?

Hello,

I have a pair of Dynaudio Contour I am driving w/ some satisfaction w/ a marantz 2230.

They are 4 ohm and 86 db so I am sure a more powerful amp would be an improvement.

I am considering a Sansui AU 7700, do you guys think it would handle those speakers or I should consider something like the AU 11000?

thanks a lot.
