fuses - the $39 ones or the 85 cent ones

My Rogue Cronus recently blew a slow blow fuse. I was surfing to find a replacement. The stock fuse is a typical metal end cap, glass and "wire" fuse. The audio emporiums only seemed to offer these $39 German gold plated end wunderkinds. I finally found "normal" fuses from a guitar amp site. Has anyone tried the uber fuses and found the sound better? Hard to understand how it could be. Thanks for any thoughts.

The fact that a product is made in a particular country that has a reputation for good quality does not signify that all the products from that country are better than products from another country. Look at the track record of Mercedes and Lexus. Just an example.

BTW, the HiFi-Tuning fuses I have look well built, so do the ones from China and Taiwan.

After 30 years of inferior materials and craftsmanship in EVERYTHING purchased from ANY Asian country(Japan being the sole exception), I have avoided purchasing ANYTHING from over there, outside of Ginseng and certain medicinal mushrooms(NO- They don't affect my hearing, or have any psycho-active effects). The percentage of defects found in Mercedes and Lexus can't even be compared with the defects found in the garbage imported to these shores(everything from lead tainted foods to counterfeit helicopter parts) from china and taiwan(I save caps for things I respect). If your tastes and inclinations are otherwise: Isn't it nice that we have the freedom to pick our own poisons in this country? What say we allow this thread to return to it's intention(the merits of the Ultra Systems fuses) and ask anyone out there if they have personally experienced, heard about or observed any kind of failure connected to the use of Hi-Fi Tuning fuses.

Would someone please provide a link to a page that shows UL listing for these fuses (whichever of the fuses being discussed have this accreditation).

I've looked at a few retailer's links, and none mention UL listing.

Rodman99999, I have to say we agree on this one.

Tvad, I'm not sure if there is a website that has which fuses are UL listed, but I think UL.com may have the list.

mcmaster.com has the certification for each product in the product specs page. Also, the accreditation has to be printed on the product itself and its packaging.

The fuse specs look like this on the mcmaster page:

Available Amps:4
AC Voltage Rating (VAC):250
Fuse Type:Fast-Acting Fuse
Visual Indicator:Without Visual Indicator
Diameter:1/4"
Overall Length:1-1/4"
Specifications Met:Underwriters Laboratories (UL)

This link has information on Isoclean fuses:

Thanks, Isanchez.

I see on the Isoclean website that the fuse box has the UL logo.

I did a search of the UL Online Certification database for both "Isoclean" and "TRC Development", and neither produced any matches.
