I also use norh's speakers and monoblocks, the original le Amps. They are driving 2 marble 9.0's and 3 marble 4.0's. There is plenty of power to drive them to deafening levels. Michael started norh as a hobby, to provide jobs for the local craftsmen, and to provide hifi gear at reasonable prices. He started the computer co a few years ago. I for one wish he would devote more time back to the audio side.
