I just got this AudioGD NFB12 in the mail last week from a head-fi'er, and the only reason I'm selling it is because I came across the opportunity to buy a Meier StageDAC. So without the luxury or being able to buy out of pocket, I have to sell this to fund it.
For the price, I don't see this Headphone Amp/DAC being beat. It sounds great!
Asking what I paid, $235 including shipping.
