Audiophile Fuses

Hi-Fi tuning fuses have been around for a long time and have received positive reviews from many quarters and are reasonably priced. The Hi-Fi tuning fuses come in two varieties, line with Cardas copper wire and the other with silver/gold. This is a nice option as it allows system voicing to preference depending on the other components in one's system. After going down the rabbit hole of fuse exploration for years, I'm happy using the HFT silver/gold in my Lampizator Horizon, Taiko Extreme and Soulution 727 preamplifier and Gryphon Mephisto amps.. Having owned the precursor 725 preamp in which I used it successfully, I recently received the 727 preamp with its factory rhodium wire fuse and could not get that out fast enough to replace it with the HFT silver/gold. Keep in mind that HFT fuses are directional so feel free to experiment. The correct direction is usually readily apparent.

I use the Hi-Fi Tuning Supreme Diamond Silver/Gold fuses on a dCS Rossini dac & clock with great results: a presentation with lower noise floor and greater realism. I also have a set of non-Diamond ones (like the ones on your pic), which I want to test, when I have some spare time.
 
Hi-Fi Tuning Supreme Diamond Silver/Gold fuses - affordable - thanks for the tip

At first, QSA fuses was on my radar, but pricey and a blown expensive fuse would be very a huge bummer. Then I considered the Swiss digital fuse box - more reasonably priced and I can demo/buy QSA other products (PC, SC, Ethernet, Outlet…), but I like the simplicity of just swapping fuses.
 
I used Hi-Fi Tuning fuses many years ago and was happy with them.

In the last year or so, I considered revisiting their use and purchasing one or two for new components in my system.

I was a bit dissuaded by the lack of any information about Hi-Fi Tuning online and what seems like far, far fewer dealers selling them than 10 years ago or so.

Does anyone have a working link to the company's website? It seems that dealers that carry them list old models as opposed to the latest model(s) discussed above this post. Does Hi-Fi Tuning still exist as a company? The idea of sticking a diamond on their fuses seems gimmicky and makes me question if this is the same Hi-Fi Tuning as used to exist.
 
You tried writing a dealer or two, such as VH Audio or highend-electronics? They must be in contact with the (German) company or its local importer.

I am aware of both of those dealers as well as Parts Connexion here in North America as well as the distributor, Wavelength.

In 2025 a company without a seemingly legitimate website doesn't inspire confidence. I guess I get hung up on that.

It's not a good look for this to be the website:
https://www.hifi-tuning.com/index_eng.html
 
Given how unlikely it is for a properly chosen fuse to blow, and the fact that their distribution network is still in place, I’m missing what it is you’re concerned about. It’s not like a component, where post-purchase repairs or upgrade or instructions are more likely to arise.
 
Point taken. That said, there's another thread going on here where discussion of "counterfeit" fuses was briefly discussed along with discussion of re-labelling basic, stock fuses and accusations of fraud or intellectual property theft with yet another company offering aftermarket "treated" fuses.

Some semblance of a legitimate company website where the public can view current models, product details, and worldwide dealers would be useful.

When you write how unlikely it is for a fuse to blow, that certainly isn't the case with one company (not Hi-Fi Tuning), as I'm sure you know.
The other company's fuses blew in my equipment (and many other people's) a number of times so I stopped using them. The recommendation was to use a different value than recommended by the component manufacturer.
 
So you think, for example, the Cable Co., highend-electronics, VH Audio would be selling counterfeits. Do you have any evidence of even a suspicion for this? These high reputation audio vendors are not Amazon or eBay. It’s perfectly normal to look for a company’s website and wonder the state of things when it looks out of date. It’s something to follow up with vendors about. However, the specific concerns you’re raising, and your resistance to just basic investigating first, suggests to me you’re new to this domain and bringing along some assumptions that may not fit.

Cable Co doesn't sell them anymore. Their affiliate company used to distribute them if I'm not mistaken.

I have not made an accusation of anyone selling counterfeits. I said another company's fuses accused of being counterfeit are being discussed as being sold by one of those vendors in another thread. I have no issue with either vendor and have purchased from both, if I'm not mistaken.
 
Which other thread? My reference to fuses lasting used the phrase “properly chosen” because yes, I was thinking of SR. I’ve never heard of such a problem with HiFi Tuning fuses (they were my first step into aftermarket fuses, although now I’m getting out with SDFBs).

Look for one of the new threads posted by SR. The discussion would give anyone a headache and I"m loathe to mention it.

What a weird thread Ted Denny created the other day! His goal is ostensibly to rebut "unfair criticisms" of SR, but then among other things he claims that blowing SR fuses are (or were?) typically the result of customers having made the wrong choices with fast- vs. slow-blow. Both from my and others' experiences, and from speaking with him on the phone directly, I know that's not the case (and why only with SR, not other companies' fuses?). As for the mention of counterfeit, that goes back to a post on a Polk Audio forum in 2021, the fuse allegedly coming from VH Audio, drop-shipped from SR. Something doesn't add up there, since Mike seems to run a straight-ahead operation. Plus, given that the fuse in question was never installed, just the outer SR label taken off to expose another underneath, it's hard to know exactly what was up with it (there are a few possible non-counterfeit explanations) -- https://forum.polkaudio.com/discussion/194604/synergistic-research-orange-fuses.

In any case, I wouldn't make any decisions about HiFi Tuning fuses based on that report or Denny's thread. Rather, seeing the current state of the HiFi Tuning website and that the Cable Co. dropped the brand suggests to me the possibility that the company is no longer around and remaining stock is it. But if I were in the market for their fuses, I'd check with vendors to see it that is true -- and if there are good deals to be had.

I am located in Europe, so I got my fuses from the dealer in Greece. I also had good support (via email) from a big HiFi Tuning distributor in Germany (kontakt@sieveking-sound.de). Attached is his price list.

I believe HIFI Tuning fuses no longer made--I may be wrong.
 
To the best of my knowledge Hifi Tuning fuses are still made, recently they have introduced their diamond series in German language groups.

I noted with some amusement:

HiFi-Tuning is the only manufacturer in the world that makes fuses by hand!

Besides not being true, it's a good reason not to buy their fuses. The key to making a fuse is consistency and reliability of the manufacturing process, including a very low solder time. This should be in the specification (see Littelfuse, for example).
