New SR Orange fuse ...

^^^ ... Yes, you have to buy the Reds, the Blacks and the Blues. This allows you to pass Go, and only then are you eligible to buy the Orange fuses. :-)

I suspect that the masking tape reduces micro-vibrations in the fuse.

The reason I found these premium fuses blow say a 1 amp fuse 
in a stock steel fuse is because the cheap fuses can vary up to 15%+ in accuracy ,where the premium fuse is within 1%.
on bigger slow blow you can only get saidvalues like 5 amp 
in a small fuse if it calls for a 1 amp ,I go 1,25 ampthis way it gives you a buffer. And I just bought for my Lampizator Amber3 dac the new orange it calls for a 3 amp 20 mm slow ,I put a 3.125 amp fuse.
these new orange fuses make your whole performance open up 
and sound more natural.   Another tip for DIY people the New 
VH Audio ODAM oil metalized poly capacitors are Great .and I have tried almost everything outthere over the years.
before going out and buying top $$ Copper foil Jupiter,Millflex  or Duelunds  these are exceptional ,not over large actually tighter wound and compact and put 1.0uf in my Dac, Stunning realism  even after 24 hours ,give them 100 hours ,and priced very reasonable vs the  Big $$ caps. Just check them out !!

What type of equipment is needed to hear the difference between Blue and Orange? I have Elac Navis speakers and an LKS dac. Am I going to hear a difference between Blue and Orange? I can get Blue for $92 and Orange for $157. Will it be worth it?

I just put an orange in my new Nord Ncore 500 amp.  Nord was including a blue fuse in their top of the line Ncore 1200 amp so if the mfr trusts them so can I.  Not exactly sure on the impact of the fuse as my amp is still in the break in period but everything sounds great to me.  Next up is a better powercord. 

oregonpapa, I just listen through the new SR orange ( just a few hours burning).  The result is difficult to discribe, but details, the sound stage,  the easy to listen to.  Do you think it might be a great upgrade to install also, on my peamp, that I would be as astonishing as the one on my power amp ?  Thank you.
