Hey everyone: Well the time has finally come to change up my long-loved system... I am selling off three pieces, at well-below market value because I am simply not interested in shipping. I live in Austin, Texas and am happy to meet another Head-Fier anywhere within reasonable driving distance. __ For sale here is a wildly overbuilt, heavy, and powerful Audio-GD NFB1-Amp headphone amplifier… With some issues. I am the second owner, bought on the Head-Fi forums about a year ago. In shipping it to me, it was dropped, and the back panel is bent., However I have not found any loss and functionality of the inputs. Also, the volume control unit was knocked off of the knob. I have a feeling that it could easily be reattached, and I have opened the case top to look at it a few times… But I’m too much of a wuss to try it myself. However, volume and input control work perfectly via the included remote, which is how I have used it. I’m not totally sure how to price this, but have listed it at $200 or best offer. I believe that’s fair considering the condition and reputation of the unit. No original box, but I can include a nice power cord if you need one. I had a preamplifier sitting atop it, which is why you see those circular foot marks… Will clean them off before sale of course. It has powered HD-650s, Grado HF-1, Grado HF-2, and Denon D2000s with plenty of headroom. I have also utilized it as a pre-amplifier, and found it extremely neutral. Yep, $200 (OBO)... Seriously, make an offer. Better images coming tomorrow !
