Why don't amplifier Companies use high end fuses?

"I can tell audiophiles are very particular about which fuses they want."

Let your ears guide you what sounds best in your system! I would like to add, don't get sucked into marketing hype with any tweaks. In my system, the combination of SR Black Quantum and HiFi Tuning Supreme Fuses sounded the best. Every component is unique and a bit of experimentation is the key when implementing after market tweaks. 

"Naysayers, you can't go through life using conjecture, insults, snide remarks, and a low and transparent level of sophistry and have any credibility"

+2 @nonoise - You couldn't have said any better. Sadly, it didn't sink in...one member here continue to blah blah his DIY skills based on a F5 clone. I mean anyone can put together an amp with off the shelf parts with proper instructions. 

When you think about it, the notion that a fuse can make a difference is not that implausible. If, as most designers of high-end audio electronics will admit, the kind of wire used for a component's internal wiring can make a difference, then why not a fuse? After all, the job of the fuse is to melt when a certain level of current is reached, so might there not be differences in how various fuses react to current at lower levels, possibly constricting or otherwise influencing the power used by the component?

Based on my experience, the stock fuse don't sound bad, in fact they sound just fine. In my system, upgraded Fuses improved the overall sound with slightly better dynamics and transients. 

As with any tweaks, the level of improvements may vary based on the components design and overall implementation. 

If you hear a difference with upgraded fuses keep them, if you don't then simply return them. It's your money and your system, do what pleases you to make it sound better! 

Peace out! 

The OP end up going with PADIS fuses, let’s give it a rest until he reports back ....no pressure right :-)

@nonoise ~ thank you for your recommendation in No. 3 response. I still can't believe it took additional 179 threads to put this discussion to rest..phew!

@dlcockrum ~ thanks for the chuckles 😉

"I feel like all the air just went out of this thread"

@nonoise ~ I feel your pain bud.

I can somewhat imagine OP anxiety, what can you possibly expect from a $25 fuse in a $60K system that already sounds great.

@russe41

What??? You didn’t hear insane depth, expanded soundstage, instrument separation, dead center midrange and everything more cleaner.....

If you didn’t then you must change the direction of the fuse :-)

@willgolf,

Great to hear that you heard improvements with PADIS fuses. Please do post your findings with SR Blue fuses. I went with SR Black’s last month in my preamp / DAC and they were substantial upgrades over stock fuses.

About directionality, if you end up installing the fuse incorrectly you should hear vocals slightly masked in addition to highs rolled off as @nonoise pointed out.

One more point, if you find SR fuse bit on bright side (and they can be with tube gear) try the HiFi Tuning Supreme Fuse. They are very extremely neutral. I end up going with a combination of SR Black and Supremes in my tube amp / pre and DAC components.

In any case, allow atleast 100 burn-in hours with your choice of fuse. 

Have fun and enjoy music! 

@mmrkaic ~ And it cost nothing at all to be a first class ’Jerk’

 

+1, geoffkait 😉

LMAO 😆.....only a lunatic (not even a skeptic) needs to try a tweak 20 times to conclude its effectiveness. If you can keep up with the count, you earned yourself that liquid-metal filled goop egg Interconnect Cable. Keep it, try it in your system and post your results with measurements.

“Well, folks, I finally tried such and such and it actually made quite a nice change to the sound. I admit I was wrong.”

Geoff, spot on bud! Nice reference to 12 Angry Men, great movie 👍
