Or is it just poorly marketed?
I use one of these to drive my HE-500 and thoroughly love everything about the little rascal. For those who already own a high quality DAC/source as I do, this powerful integrated HP amp seems to me to be ideal, at least for a fairly easy to drive planar magnetic such as my cans. Nevertheless, there seems very little interest in this Audio-gd product compared to so many others in their line-up and I just wonder why. Has Frank I's rather negative review soured potential buyers of the NFB-6?
