Usher cp 6311


I am interested in buying a pair of usher cp6311's and would like to hear opinions on needed amplification used

Mine sounded best with my Muse model 160 mk.II amp. They also sounded quite good with a raysonic SP 120 KT 88 integrated.
Thanks for all the responses - I currently own a Music Hall Mambo integrated putting out 50 all class 'A' wpc. I couldn't get my head around the 87db efficiency rating & if I would be able to listen to music on the 'loud' side once in a while.
The CP-6311 is not too difficult to drive. I drove a pair temporarily with a Peachtree Decco which has a 50 watt chip amp and it sounded great even at moderate levels. 50 class A watts should work just fine.
