Lumen White?

Does anyone have much experience re Lumen White's Silverflame or Whiteflame D speakers? I recall quite awhile ago Stereophile doing a so so rvw on one of their models (probably now discontinued) and Japan;s Stereo Sound raving about the top of the line DiamondLight model, which is out of my price range. They look beautiful, seem to be easy enough to drive....
