Synergistic Red Fuse ...

Agreed Charles. One Black on the way!

Bill,
Which component are you starting with? In my system the greater perceived impact was Line Stage and DAC  (equal) then the power amplifier.  Of course there's hierarchy variations depending on system/components. Wow! What a comeback win for the Detroit Lions 😀

It have about a hundred fifty hours on my black fuse on my dac . I think it has stabilized now. But man, it changed continually.  
And then I couldn't believe what I  was hearing. So I go to my hearing doctor. He says put a little lime in your coconut and listen to what I have to tell you.  Your hearing does not lie. You really are hearing all that gloriously sounding music just the way you described it. The unbelievable dynamic contrasts, yes.  The full harmonic structure of all those musically instruments, yes. Telling a tight group of musicians from a sloppy group, yes. Hearing a bartender inviting you to drink along with the other listeners in your room, yes.hearing a popcorn kernel roll along the floor, yes. Music that is not confined to a sound system, yes. 
Then my doctor said go home and put some lime in your coconut and drink it all together. Enjoy yourself and don'the worry about how your system use to sound, just bath in the musical glory you have now. 
So like Tony the tiger says 'It sounds grrrrrrreeeaatt!'. In other words better than it ever has. I still cannot believe it is just a fuse. Pinch me.

In my system and I have tried them all . The Hifi tuning Supreme in the Black case brought out the best resolution. The SR are still very good more warm balance . The Hifi tuning Supreme slightly warm but give it up to 100 hours to 
fully settle in if possible just let play. The difference is in low level resolution 
and at lower volumes that is where the extra information shines. I have spent 100s of hours comparing . The Audio Magic very good more warm use  honey 
or something similar and want over $150 each way yo much money.
parts connecxion Canada has had fuse sales up to 20% off, and discontinued older models worth seeking out. Over 50% off.. nothing is set in stone 
remember the standard fuse resistance index is almost 8x that of a Silver conductor.  SN research do a lot of BS also and I owned everything like the new 
tungsten Element cables .all these active spaghetti wires totally not necessary 
and to offer a upgrade wall wart plug for each cable . $400 each .i had 16 cables.
pure marketing .PT Barnum said it best ,there is a Sucker born every day .I owned a Audio store for 10 years inEurope and have se it all in ways to part with your hard earned moneys.
tube USA sell  Synergistic up to 25% off with purchase they get 55% off.Sound cable  engineering is most important .0-or single crystal Copper,or Silver actually does bring sonic benifit 
and quietness across the board vs standard 4-9s Copper.go to Neotech look at grain structuring .only 3 companies make and a high % companies use this Shunyata, Analysis plus, Acoustic zen,Zenwave  and many others.high quality connectors also count ,thinner is better less RF possibilities. I had to clear the air ,just look for solid engineering 
not  so Called breakthroughs - bells and whistles !! 

Hi audioman58,

Good to read your impressions of the various fuses. Too bad you used the post to editorialize about cables. My experience with SR products over many years is completely contrary to yours. As there is no Virtual System posted for you, I have no idea as to your frame of reference.

It is comical to read your adamantly supportive comments on boutique fuses followed by complete ridicule of high-technology cable products. I suppose that the latest Graphene products from SR and Cerious Technologies are fool’s fodder also?

In order to avoid a protracted series of flaming posts, I must go ahead and concede to being easily deluded with PT Barnum-like power of suggestion, yet I feel confident in defending my God-given skills related to hearing and, just as importantly, discerning great sound.

Best to you audioman58,
Dave
