It's for someone who likes to build, not an audiophile, not when the 3116 is around.
I lived with GC's for most of my audiophile days. For the money they were nice, better than old but not cheap commercial class D, and other things up to a point. But.... they just can't do what a 3116 can. They're forwardness was fun, but inappropriate to the accurate bliss of the class D that doesn't make that sacrafice.
