Something For The Fuse Guys ...


There are fuses, and then, there are fuses. 

I'm evaluating some prototype fuses that I received in the mail three days ago. 

Over the past few years, I've used fuses from five different manufacturers. The last three were the Red, Black and Blue fuses from Synergistic Research. Each one incrementally improved the sound of my system. My favorite so far was the SR Blue. 

The prototype fuses being evaluated presently raises the SQ beyond all of the others mentioned above. The major improvement to my ears is better tonal accuracy. Instruments and voices are more life-like. The noise is reduced allowing for a more solid 3-D presentation with the musicians more solidly presented on the sound stage. Overall, more information is fleshed out of CDs and LPs. 

The manufacturer, the price and the name of the prototype fuses will come later. I don't have the information thus far. My understanding is, if all works out, the release date is to be mid-October. 

Stay tuned ...

I did a fairly extensive test of the efficacy of SR fuses a while back...recorded results to play for reference, tried reversing them, had one blow for no apparent reason, and otherwise tried hard to see if the things made any difference...they don’t, and another interesting thing about the endless nonsense regarding Magic (and expensive) Fuses is nobody has offered up any reasonable explanation why they would. 
Whoa! What the ding ding?! Folks, can you believe it? we have a tie!! Pseudo skeptics 4, fuse apostles 4. We even have wolfman and madman repeating their same dreary claims of “extensive testing” and that nobody has explained how fancy fuses work. Yawn! I’m feeling a little sleepy. Now, get back in there guys and let’s see the feathers fly.
Mapman sez people can draw their own conclusions. Oh, you mean like the 100,000 happy campers who have bought audiophile fuses? Good detective work, Moops! 
It is simple to test if your fuses are limiting something without having to invest hundreds of dollars.    Just jump them with some spare wire and have a listen.  You can even get fancy and jump them with pure silver solid or other exotic wires.    If you can't here any difference it is unlikely a fancier and expensive fuse will work.
You can decide if you want to live on the edge and skip the fuses.   I never blew an internal one in anything solid state.   
I'm just slightly confused!  Can someone explain to me which order one would change (upgrade) fuses for max benefit?  A/C input surge fuse,
DC power supply fuses, speaker fuses?  Of course testing after each
change.  

I can't imagine the AC power line fuse would make any difference. But, it does make a little bit of sense that a speaker line fuse could make some difference.

My ARC D-110B has speaker fuses, when ARC upgraded that design
with MUCH better components they also eliminated the speaker fuses.
The fuse holders (at least the frames) are still in place they are just wired straight through. Given the cost of the amp I don't think they were cheaping out on a fuse.
