Which SR Blue or black Fuse

So I think I will let this first SR Blue settle into my amp for the next 100+ hrs or so before possibly adding another.  Any consensus on where I'd get the most bang for the buck in placing another? Choices are either my streamer/DAC or preamp.  I run the streamer/DAC through my preamp.

My Mytek Brooklyn DAC by far gave me the largest jump in SQ of the three items I have BLUE fuses in.
The other items are Ayre ax7e integrated and Goldnote ph10 phono stage.
