The NFB 11.28 is basically a Schiit Uber Stack compressed into one ugly package. With the added features of better internal components and higher quality parts.

The price/performance of this DAC/Amp is great considering you get a very good amplifier that will power 99% of headphones out there and a DAC with all inputs necessary to make this your desktop audio hub. If you feel adventurous you can start fiddling with the build in equalizer settings that are available via dip-switches on the motherboard. Eleven different filters can be applied to DSD and PCM bit streams when you dare to rip that thing apart and get your hands in there.

When should you get this?

You are looking for the swiss army knife for audiophiles and don't mind buying from AGD like its 1998

Go crazy on the dip-switches. The filters will allow you to apply a hardware "equalizer" to your sound. The manual has all the info you need...you just need to extract it: AGD NFB11.28 "Sound Flavors"
