The NFB-1 is currently in the testing phase and is based upon the RE5 circuit (in so far as the RE5 base circuit can be used) and packaged in the mid size ROC/RE5 chassis box. Looks like this DAC should be a real high quality contender in the sub 1.25K range. I'm guessing about the price range ( maybe 900-1.2K ?) hopefully it'll come in under 1K vs the pcm1704 equipped RE5.
