Up for sale is an Audio GD NFB-5. It has inputs for optical, coaxial and USB. The RCA outputs can be fixed or variable. That means this unit can be used as a digital pre-amp however it lacks a remote. Currently the jumper is set at variable and the jumper pin is taped to the inside top of the case. I used it with my Beyerdynamic DT-770's and it works great.
The unit can handle 24/192 over coaxial and 24/96 over USB. I have slideshow of the spec's for the unit here. Price does NOT include shipping.
Any questions, just ask.
