I just saw on the Audio-GD website the new NFB-10: http://www.audio-gd.com/Pro/Headphoneamp/NFB10XLR/NFB10EN.htm Seems like the high-end version of the NFB-11 to me? Interesting to note is that the front plate of this unit says "Roc", so maybe this is a Roc unit with built-in Sabre DAC? I can't find the price for this unit, but I'm guessing it's going to be more expensive than the $680 Roc unit... But maybe there's a pleasant surprise in terms of price
