I own a set myself and give them 150w/ch from a B&W. Bob lives down the street and uses a variety of amplifiers from class d JVC's & Wyred 4 Sound monoblocks to 50w/ch class A's. I've found that if using solid state just make sure it's a good unit with headroom. Call Bob if you want to know about the class A that he recommends if you are interested in that route.
Hope this helps a bit because I've found that most good units work fine.
