Having lived with a pair of Little Horns and one of their stereo tube amps for a while, I will say they can be fun to listen to. They are not 'audiophile' speakers, though. I would be reluctant to use SS amplification with the speakers, although their powered sub with the built in stereo amp for the horns makes up an OK inexpensive system. The Hornlings may be less efficient than the Little Horns, but I wouldn't put big SS power on them.
