[Where?]

I believe that's referring to the quality of the SPDIF and USB inputs to the FNB-11 (player [software or hardware], PC, and/or other upstream device(s) in the signal path); not the FNB-11's implementation of the ES9018 chip's capabilities. Both the Hiface and Audio-GD DI digital interfaces are asynchronous and capable of outputting 192Khz/24bit signals if presented and both a) the input signal at that rate is clean enough, and b) the physical connections are good enough (notice at high bitrates/sample depth no optical SPDIF, coax only, and the Hiface needs the BNC connector). Oversampling appears to a function of the upstream source player software/firmware and hardware capability (for example, the foobar program oversampling upto 192/24 is a software switch); perhaps the designer should weigh in here
I assume the FNB-11 ES9018 (having eight 32 bit DAC channels) is configured in "Stereo Quad Balance Mode," utilizing 4 D/A converters per channel; but, again, perhaps we should hear from the designer. The chip clearly has more capability than implemented in the FNB-11. All I can say for sure is that, so far, it sounds really clean and really detailed; i.e., good to my poor ears. As noted by others, too easy to play too loud.
Where can I get this fabled, "FNB-11" from?
Joking aside, are you guys using the power supply with the digital interface?
