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.

Hey it is Mr hypocrite himself, the Toxic Kid.
Welcome George!

What’s the next toxic thread you are going to start just to cause trouble?

Btw, if you can't stand the heat keep out of the kitchen.

Just keeping an even playing field here.

Your "3 x the sound quality" statement says it all, there is really, nothing else to be said about you and the other fusers.
And if the gullible believe you, then they deserve getting ripped off for $$$ for fuses.
