Power requirements for a pair of B&W805S spkrs.

Looking for some recs on a good integrated amp to use with these speakers. Would the Yamaha A-S2000 be a good choice?
I owned those B&W before i bought my current Magnepans.
I used a Forte'4a with 50 watts per channel and it was great.
So most amps will power them just fine.
The issue would be the quality of the amp/you listening to determine the level of refinment in an amp for yourself.
So it is your own ears which need to be the deciding factor as which amp is good enough.
