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.

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.

Thanks for not forcing your opinions on us. :-)
JD, Thank you for bringing up the important point about IsoClean recommending replacement every 6 months or 7500 miles whichever comes first. OK, I embellished a little. I just finished doing the 6 month oil change on my car. I did not see that information on the web site so I am glad you brought it to my attention.

I have three amps with 6 fuses each. Only 5 are sizes that IsoClean makes. A dealer recommended only replacing the main 8A fuse but even that requires me to remove an amp from the system and take the top off. Three amps equals three times the expense, three times the labor -- every six months----no thank you.
hi JD, all that you get for "literature" that comes with the HF Tuning fuses is a little piece of paper that has a name of the company and web site address. No instruction manual. No mention of fuse degradation. This sounds weird to me that the Isoclean fuses need to be replaced every 6 months. Glad I didn't get them and went with HiFi Tuning instead.
If you read the IsoClean literature, you would see that all fuses experience the shock of surge current. In other words, according to IsoClean, all fuses should be replaced every six months. I have no real plan to replace my fuses every six months. Like all products of products that are consumed, the manufacturer encourages quick usage. Change your rasorblades every week, change your oil every 3000 miles, etc.

Are you guys new to a capitalistic society? You should neither believe everything you read nor disbelieve everything you read. I had experience with direction of fuses being important and so far I have found that the direction IsoClean indicates for their fuses sounds best. I will, however, keep trying. I wish I knew why the direction they say is so, but it does seem to work.

HiFi Tuning fuses also have a "best" direction, but they do not tell you which is which.

Jadem6, who has to always be right? Most of us are limited to our personal experiences, and I suspect few of us would choose to buy what is second best in our judgment. We just differ in what we find best.
