Replacement Fuse's - What are my options ????


Do to a dumb electrical move I blew a fuse in my amp and thankfully it did just what it was supposed to do. No damage to my amp. What are my replacement options ???? I have heard some audiophile fuse's are out there for $25 a fuse....any comments would be appreciated.

Aggie, my price sheet shows one line item for all Furutech fuses at $60 each which I confirmed with the same Patti as mentioned above.

BTW, what type of law do you specialize in?
I've replaced 4 external $.035 fuses with 4 Isoclean fuses and within 48 hours I could not hear any difference whatsoever.

(In my experience, simple electrical and some line conditioners take about 48 hours of burn-in time.)

Several days later I replaced the 4 internal fuses on each rail of my amp. Within 48 hours the sonic improvements were about equal to going from audio grade wall receptacles to cryo-treated and higher audio grade wall receptacle. In other words, a very noticeable improvment.

A noticeable amount of graininess was gone and replaced with a richer, warmer, more detailed and pristine presentation. The improvements were well worth the money.

There is another fuse mfg'er called HiFi-Tuning.com that appears to produce an even better built and better materials fuse than the IsoClean. I've replaced that equipment and left the fuses in place (accidentally). This next round I'm going for the hifi-tuning.com fuses.

With regard to safety, there should be no difference. Safety and construction and blow are the sole purpose for a fuses existence and easily understood even by somebody like myself. An audio grade fuse simple replaces the very cheap alumimun and glass materials with silver, copper, gold-plating, and ceramic type materials.

There's probably more voodoo just by mentioning the subject.

The key to safety is replacing a fuse with an identical spec'ed fuse including amperage, size, and type( slow or fast blow).

Aggielaw, if you've only replaced the fuse accessible from the back of the amp, then you might consider opening the lid on your amp to see if there are a few fuses on either rail inside your amp.

On my DNA-2 Rev A amp there were 4 internal fuses (2 per rail/channel) and replacing these fuses provided substantial sonic improvements perhaps because they are in the direct signal path.

Aggielaw, so you're moving from a very dry climate to Kansas? This should be good. :)

My family and I recently moved from Leawood, KS to Oregon. For 3 months of the year, the heat and humidity in Kansas is literally as bad as summertime in Orlando, FL.

But suprisingly (and aside from the humidity) KS was a fantastic place to live. My wife, who grew up in Rancho Palos Verdes, CA aka the Beverly Hills of the west side, cried when we moved from Kansas.

BTW, you should experience lightning and thunderstorms that will scare the cheese out of you. So you better buy 8 fuses. :) During the stormy months, I unplugged all equipment when I wasn't listening.

Anyway I hope you enjoy KS as much as we did. We'd go back in a heartbeat.

Geoffkait, you might want to open up the top lid of your components and trace the power wire to verify the direction of power in the fuse holder. In my previous components all externally accessible fuse holders had the power wired so that a properly installed IsoClean fuse arrow was pointing out the back.

The opposite of my assumption.

Now if only somebody would build a gold-plated cryo-treated fuse holder.

-IMO
I don't think anybody mentioned the Furutech fuses which I just stumbled across. These come with a pure silver conductor, rodium plating, and cryo-treated to boot!

I've owned the excellent IsoClean fuses, I'd like to try the hifi.com fuses, but I think I'd have to go with these next.

I just happened to come across them as I'm in the process of applying for dealership status with Furutech. It appears that the retail price is $60 each but I'd have to verify.

I initially choked just a bit at the $25 price of the IsoCleans but considering the build quality and materials of these fuses along with the cryo-treatment and potential for performance gains (when compared to other upgrades), it doesn't seem so bad.

Interesting, Aggie. I spoke with Patti yesterday to confirm the $60 price on my price sheet.
Mitch2, I used to own the DNA-2 Rev A amp and shortly before I sold it, I replaced the internal fuses (2 on each rail) with four Isoclean.

It took about 48 hours of burn-in and after that the improvements were about equal to replacing standard wall receptacles/outlets with cryo-treated Oyaide outlets. Not identical improvements but the percentage improvements were about the same.

More detailed, lowered noise-floor, and a richer/warmer overall presentation. It was well worth the $25 x 4 improvement.

Just don't forget to account for them in your price should you ever sell the amp. I forgot.
