I have an Edge NL12.2 and think it is fabulous. Transparent, dynamic, toneful, powerfully- everything you can and should ask for in an amp in that price range. System matching is always important and the Edge amps like a fast, clean sounding speaker that can image and throw a soundstage. I've never had any issues with Edge amps. Both the new owners and past owners have been great to work with.
My current set up:
Esoteric k-01 and separate clock
Edge NL 12.2 amp
Edge NL 1.2 pre amp
Custom speakers using Accuton drivers
Virtual Dynamics cabling
