Heh, interesting feedback. I actually have found that the normal Hi-Fi Tuning "Supreme" fuse works the best in digital transports or anything that does a "digital only" circuit. Silverstar is just way too fast/bright (same with Synergistic SR20). Other fuses, such as Furutech/Isoclean, are just way too slow/warm for digital transports. I use a dedicated linear power supply for my Lumagen Radiance video processor and the video was the cleanest with Supreme fuse. Any other fuse would show grainy/dirty video.
As I have said before, my "go to" fuse is Furutech rhodium, but I will use Hi-Fi Tuning Supreme in some instances where a sound or circuit is too slow/warm. I have found other instances where I need to use a very warm Isoclean or "Supreme Cu" (example would be a Bryston Amp).
I have not tried BLUE or BLACK or Audiomagic fuses. BLUE is on my list for something to do when I run out of everything else.
Fuses are a tool to help tune a system. There is no "best fuse". Just like there is no "best amp", etc. etc.
