Whose got best class D at this point?

Bel Canto,PS Audio,Redwine what am I missing out there for either hi-effciency speakers like the Redwine Sig 30 (great review in 6moons and sounds like it would be great with Silverlines or my German horn Odeon Tosca's) or for current hungry speakers the PS GCA250 or Bel Canto 300.Think after years of onventional SS and tubes might want to take plunge but want guidepost to best bet for the money.
Thanks
