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?

Can any of you explain why an item such as a fuse, which breaks the signal path, has such an impact on sound?

I'm not poopooin' it, just asking?

My amp, McCormack DNA-225, upgrade to a, (SMC Ultra 15), had the Hi-Fi Tuning fuses oriented for sound by a machine they have, in-house, for sonics.
I haven't researched this topic. I'm just posting on it regarding my current interest in it.
almarg:,

Your post makes more sense (to me), rather than trying to explain, in some fashion, things that cannot be explained or measured, but can be heard by listening.
Yes, I can see that.

Having said that, why don't interconnects have a similar, instant, correlation? With interconnects, there is the obvious issues of break-in, the affect of insulation/dielectric, ... and so on.?

 
geoffkait:,

"I trust you are not suggesting fuses DON'T experience break in"

I did not say that. It's an issue that I just don't recall reading about.

What I read the most, regarding the "instant" effect fuses have in one's system, is just that, it somehow (instantly) transforms the sonic signature of a given component. I NEVER read that, say, upon, hours of listening, this fuse has gradually made my component better in upon hours of listening/break-in.

This may be the difference in our opinion.
If I were to devise an interconnect that had a "fuse" in it's construction, (would this same argument be made)... "it's a part of the signal path"?
geoffkait:,

"the fuse doesn't break the signal path, it is part of the signal path".

Can one assume this statement transfers to say, a tonearm wire (from cart to preamp?

In my system, the less "breaks"/additional connections, one has in the signal (regarding the path from a cart to a preamp), the better the sound.

Example: I fashioned a tonearm wireloom for my ET arm that took out two connections that I originally had. The sound quality improved by a wide margin.

Can this same/similar instance, correlate to the role a fuse has in the signal path?
 The OP wrote:..."there was an immediate improvement upon installation".

This statement alone was a verification of an immediate sonic improvement, without the benefit of further listening. However, the OP did go on to say that subtle improvements followed.

This is just (one) example of the "instant" effect, I base my posts on regarding this tweak.


This all sounds fantastic. One would think that manufacturers of audio equipment will soon be striking deals with SR to have these remarkable devices included as standard in their products. It would seem to be a "win..win" based upon all of the positive comments.(Maybe not a win for SR, in one sense, considering their mark-up would diminish.)



Oregonpapa,

I guess my reasoning would be that the more demand SR has, the more they would manufacture at a time.....bringing costs down.

I assume high-end audio works differently from normal retail manufacturing?

If my amp didn't take 7 fuses, I'd be more willing to give them a try.

Cheers!
Curious about the related (sub)/fuse issue. Are (you all) referring to any/an/ amp/plate fuse or the A/C inlet fuse?

Anyone here using a Martin/Logan Depthi/ any experience with this sub, regarding aftermarket fuses???
