what if we want to get 3.3V. I agree the Reflektor D will work for such low voltage but is there a way to use mosfet instead of BJT for the shunt for the 3.3V.
No, there is no PMOS with low enough Vgs threshold to use in the BIB that I have successfully tested to recommend. 3.3V BIB calls for BJT output version only.
I could not measure any 100Hz ripple with the average bench equipment I got.
How did u measure it which hardware and software was used?
Is the noise as low as 20 nano volt?
As long as 1000uF is there as main Vref filtering you can bypass it with 10nF or whatever you want. Technically its not a problem. Just try to keep it short legged. Subjectively you decide about it in your application and system. In our old trials bypassing that capacitor the opinions were inconclusive.
Salas there is one thing which is bothering me regarding the 3.3V output for the Reflektor D output and the Bib.
As mentioned in the earlier post that for low voltage operation the Bib needs transistor at the output and in some other threads its mentioned as using BJT will give lower output impedance > Im not sure output this.
But when it comes to 3.3V output some forum members have mentioned that using Reflektor D resulted in some recessed highs.
I like the sound of the Bib but using 3.3V for the digital section of the DAC which one is better?
Reflektor D or Bib?
What is soo unique of reflektor D when Bib can actually Do the 3.3V?
in other words what made you think about Reflector D concept?

BJT will give the graph that is included in the BIB manual for BJT.
How do they use that REF-D ? With 1K R6 or with a JFET in its place? R6 will give impedance more like the BJT BIB. JFET will give more punch.
For the concepts history see back through their first page links, because it would take too many words to recap right now
