Synergistic Red Fuse ...


I installed a SR RED Quantum fuse in my ARC REF-3 preamp a few days ago, replacing an older high end fuse. Uhh ... for a hundred bucks, this little baby is well worth the cost. There was an immediate improvement upon installation, but now that its broken in (yes, no kidding), its quite remarkable. A tightening of the focus, a more solid image, and most important of all for my tastes, a deeper appreciation for the organic sound of the instruments. Damn! ... cellos sound great! Much improved attack on pianos. More humanistic on vocals. Bowed bass goes down forever. Next move? .... I'm doing the entire system with these fuses. One at a time though just to gauge the improvement in each piece of equipment. The REF-75se comes next. I'll report the results as the progression takes place. Stay tuned ...

Any comments from anyone else who has tried these fuses?

Wow! Your description is dead on as to what my results have been. Isn't it interesting that "bassdude" and I have the same preamp (ARC REF-3), and yet we've gotten completely different results.

The first fuse I tried was an SR Red in the preamp. I was blown away by the results. Then, two days later I had my friend Robert over for a listen, not telling him about the fuse. All he knew was that I had made "some kind of improvement to the system." I left it up to him to guess what the improvement was. He guessed new cables, tube rolling, magic dust. When I told him it was an after market fuse upgrade, he wouldn't believe me until I showed him the box the fuse came in. He's a definite believer in the SR Fuses now ... and he is pretty much anti-tweaks and a real critic. 

I thought geoffkait's Tice Clock story was interesting. I've spent an inordinate amount of time and money eliminating micro vibrations in my system. I'm thinking that that may have something to do with the outstanding results I'm getting from the fuses. The system was already (I thought) a very high resolution system. The upgrade to the SR Black fuses have brought me to the level you are experiencing. 

Perhaps you're right in your assessment of moving the fuses in and out to make a-b comparisons. I'm hoping that mapman will leave the fuse in place for at least 50 hours before he gives up on it. It wouldn't surprise me if his fuse needs to break in all over again as it sat on my shelf for several weeks before I sent it off to him. 

Al ... I have to say, you make this site very interesting indeed. Love reading your technical explanations. I don't understand it all ... but I do pick up some of it. I'm terrible at building stuff ... but I can sell the bejeezus out of it. *lol*

Crazy stuff for sure ...
Well, I've just discovered that the PS Audio Power Plant 300 actually prefers the Red fuse over the Quantum Black.
A friend of mine, who loves music (well, let me correct that: he loves Scheherazade, and ONLY Scheherazade), was over the past few days, so last night, I decided to play the vinyl version (I think it's a Classic Records release, but don't hold me on that).
SO. We listened once and suddenly I wondered, because the sound was just slightly strange sounding, what it would sound like with the Red fuse. So, I popped out the Black and put in the Red, and put the needle on da record and wonder of wonders, it sounded better. So, I began changing the orientation of both the Red and Black and in the end, the Red sounded better than the Black. I have no idea why. Don't even suggest burn in: it's been two weeks, 24/7 in the Power Plant with a fan hooked up to it, too.
Hey, no skin off my nose: I can put it in the NAD C356BEE integrated I'm giving to a friend and see how it sounds there! But it was a surprise and no head scratching was required. Dave said, it sounds better this way, and that was with the Red fuse in it. Go figure!

"Geoff. For someone always declaring straw man arguments of others you sure are a champ. What does a tice clock have to do with fuses? Answer: Nothing."

Actually the list of reasons why audiophiles sometimes don’t get the results they expect is not a Strawman argument. A Strawman argument is by definition a misstatement of the other person’s position in an argument or debate. The difference is we are not actually having a debate on your test of the Red fuse. So I cannot be misstating your position. I’m simply offering possible reasons why you had an unsuccessful experience with the Red fuse. Maybe you can add to that list.

These reasons are the same for ANY audiophile device, whether it be a fuse, a cable, but IMHO usually involves a controversial audiophile device, one that often creates some angst and trepidation in the audiophile, perhaps especially when it’s done in public. Maybe there is some psychological aspect to why audiophiles sometimes get negative results with certain audio devices, things like clocks, silver foils, Shakti Stones, Schumann Frequency Generators, crystals, tiny little bowl resonators, green pens, purple pens,....fuses.




Mapman, I suggest you re-install the sr-red fuse and allow it to burn in for 150 hrs,  regardless if the fuse has been used,  the fuse in question here has not been used for week's, that said,  to finalize a impression, it would be fair to do so. 

Well, plunge taken. I ordered a SR Black fuse for my preamp today from local retailer Bravo AV (Tom, the owner, is a great guy; I’ve known him a few years). I did call SR prior to placing the order for some reassurance (especially after my preamp manufacturer "de-recommended" aftermarket fuses) and to find out if the SR 5mm size would fit as a replacement for what I measured as 4mm in diameter and 2 cm in length. Of course, if it won’t fit, I can return it.

Also found out from SR that their fuses are UL listed, which I find comforting.

I will post my impressions once I have a chance to install, break in, and do some critical listening.

Thanks to everyone here for their posts. They were helpful in enabling me to make this purchase.
