Isoclean fuses: definitely worth it


I just installed Isoclean fuses in my Naim CD5x and Nait5i. I sort of felt like I was going to the fringe by installing these but keep in mind they are right in the AC path so it made sense to me after installing a dedicated line and an "audiophile grade" AC receptacle.

I tried Buss ceramic fuses beforehand and they were just slightly better than stock.

The Isocleans, however, definitely provided a noticeable improvement over stock or Buss ceramics. In a nutshell: smoother treble, a touch more overall resolution (especially in the mids and treble) and elimination of a bit of grain and veiling. Polarity does matter. I checked a few times to verify but arrow down for my equipment was more natural (less bright) than arrow up. You may prefer the other polarity, of course. Note that they didn't affect rhythm as many products do (especially a lot of isolation devices) nor did they add any brightness (at least in the polarity I prefer).

They're not cheap for what they are ($25 per fuse) but the improvement was definitely worth $50 total investment to me.

"does anyone know which is better, the Isoclean fuses or HIFI tuning?"

Experience obviously differ but HiFi tuning and some other audio grade fuses I tried has left the Isoclean in the trash.
Well to be blunt there may be good reason that the HF Tuning will "won across the board" versus Isoclean, as another Gon' member put it. The simple truth is though Iso and HF are priced similar, they are not made equal but more likely the result of usual inflated pricing with Isoclean products.

Whether it is possible to get HF Tuning in Europe at halve the price I can't tell, but I would certainly be interested in getting audio cables at 1/3 of what they sold for in the US. I would recommend anyone thinking Isoclean "definitely worth it" to take the benefit of the doubt. There are better choices out there.
I think it may be the AHP fuse from Germany that you are referring with Paul McGowan. Featured in PS audio's newsletter this month.

You do made a valid point, though I am less certain the trasportation, etc., could wholly account for that much difference. I do ackowledge however that I might have over-reacted; and feel sorry if in anyway I might have appear to have been dis-respectful in forcing my own opinion upon you. That's not my intention, but I do feel the way those Isoclean Chinamen price their products are bordering on dishonesty; or looking for fools; and I do have a strong distaste for that. You are an open-minded person and I am glad I learn something from you with this discussion.
Geoffkait, you are welcome.

Now here is a simple explanation from Isoclean itself of why replacement every now and then is necessary. I quote this from an audio article written by an oriental reviewer living in Seattle. I can actually read their language and translate them for you. There are of course sematic differences which cannot be 100% translated so bear with me.

"Because of the few samples on hand, I haven't directly compare AHP against Isoclean, but both are effective. According to the properitor Mr. So of Isoclean, their fuse have limited life, and even if not bow up, overtime the sonics with degrade, the primary reason being that the thin conductor core within cannot withstand overtime the micro heating from prolonged passing of current; or the instaneous heating up upon switching on of the equipment will cause change in the thin conductor core, resulting in the fuse losing its initial glamour and softening in sonics. Based on my observation over the months, the effect described is in fact true. Looks like we have to replace our fuse from time to time to keep up with the sonics".
Tbg,
Note that I was quoting the article to address the question raised by JD, i.e., "What I would like to have discussed is the fact that Isoclean claims you will need to replace their fuse every six months due to degradation of the fuse". Nowhere did I mention that this situation is limited to Isoclean. And indeed Isoclean made public such situation, even if the Gon' members have a problem with that. I was only offering an explanation given, one that is not commonly available to Gon’ members. The explanation from yours may be better, but I do find they share a common theme.

I thought we are over with Isoclean versus HF Tuning. Really you don’t have to seize every opportunity to find fault with my posting. If I have a vendetta against Isoclean, I have already declared above that I find their practice bordering on dishonesty. Faking a product several hierarchy above what they really are smell dishonesty to me. Pricing a Honda as Mercedes to unaware customers smell dishonesty to me. Here my friend is the lyrics from a song from Billy Joe : “Honesty is such a lonely word……..Honesty is hardly ever heard…..most I need from you.” Call me cynical but I don’t think the Gon’ members are interested in my moral standard, and that doen’t affect the explanation offered in the article in anyway. You have a problem with that ? Drop me a PM and we can discuss this topic.
"replace their fuse" "Nowhere did I mention that this situation is limited to Isoclean"

If you care to look closer, the writer of the article actually wrote "replace our fuse". To quote in full, "Looks like we have to replace our fuse from time to time to keep up with the sonics". I think the writer was referring in a general sense to most fuses and not specific, but I won't make it out of proportion one way or the other. Tbg, why the Freudian slip ? Take care.
