http://www.scott-nixon.com/Scott needs to update/fix his site, but he's probably very busy. He offers 20 wpc stereo models starting at $400 and goes up to $2,000 for a pair of 40 wpc monoblocks in fancy cases as well as parts for DIY. I've heard that his prices may have come down as he has changed to cases that are easier to work with. And of course he sells his nearly famous DacKit, TubeDac, etc. assembled or in kits. Now if he'd just add a simple preamp with remote control...
BTW Ronnie, from the Carolina Audio link, builds Jordan 92S single driver transmission line designs and 2-way transmission line speakers in the lineage of Irving M. (Bud) Fried that don't need subs.
