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.

This is the wording of the above that I have from IsoClean. "Fuses always carry high electric current thereby causing metal fatigue. This would then adversely alter the conductivity behavior of the fuse element and hence the performance of the equipment." Notice that there is no suggestion that this is limited to IsoClean fuses. I think Greeni that for some reason, you have a vendetta against IsoClean. Why, because they cost less than HiFi Tuning fuses?
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" Huh!
As i've mentioned in other threads, simply pulling and replacing fuses can improve conductivity. This is due to breaking up corrosion and making fresh metal to metal connections. Whether or not this is audible would depend on how corroded those contacts were.

Other than that, maybe Isoclean has found that the corrosion takes appr 6 months to build up to the point of measurable degradation, hence recommending this as the interval to replace their fuses. Replacing the fuse at this point "might" achieve the same results as simply cleaning the contacts on the old fuse and replacing it.

One approach is obviously a lot cheaper than the other whereas the manufacturer stands to profit from the other. Use your own judgment and go from there. Those with the Isoclean's and / or HiFi Tuning fuses aren't the only folks that can try this either : ) Sean
"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.
