Nice Frank!  I ended up ordering a blue QSA fuse from Tweek Geek to try in my dac where there is an SR Orange. I've spent $240 on the AM's latest fuse and I really like it in my integrated amp so a yellow one would be a good comparison there for me.
“Is there a 30-day return policy on the yellow one?”

At least from Tweek Geek, yes.
2nd Note;
for those who are trying/using these Fuse(s), which brand did you leave?
Anyone leave Hi Fi Tuning (for example) ?

Happy Listening!
Tommy were these fuses placed on the ac side of things or on the dc side. Tom

DC rail fuses🤢🤮
