Fuses that matter.

"As good as I thought the HiFi Tuning Supremes were, they are now much better. I had relied on the information I got from my amps' (BMC M1s) imported about the direction to be used as well as that of the HiFi Tuning importer on how to install the fuse. Friday I did an A/B direction testing. I had it in wrong."

Hmmmm...one wonders if Bryon Cunningham installed some of the fuses incorrectly during his recent testing of aftermarket fuses. If so, that might explain his less than stellar results. I suspect it would certainly help to know what an incorrectly installed fuse sounds like - noticeably harsher and more "electronic".

Bryon did not demo the newest Supreme fuse that I found considerable better than there first two efforts. There were some measurement tests on fuses on one of the zine sites that were very interesting and enlightening, don't recall which one. What was interesting was they all measured quite different.

Tmsorosk, what with directionality being an issue (except in the mind of skeptical couch potatoes) I have lost faith in ANY tests of fuses unless the person performing the tests is already familiar with the difference in sound fuse direction makes and unless he goes through the laborious procedure of trying each fuse in both directions as he proceeds. Not to mention the unplugging and re-plugging the power cord thing. There is a right way and a wrong way to get to the bottom of this thing.

I'm with Lacee here. If it makes a difference it makes a difference. You can read the white paper later.

There is a curtain amount of "voicing" a system that comes from small tweaks which when all added together can bring a refinement you would otherwise have missed. Fuses are in this catagory to me along with power outlets.

The question is where to start? Tube amps & preamps are a no brainer for fuse replacement in my experience, as long as you have paid attention to cabling & power supply too.

Which manufacturer of fuse is another question. Hifi tuning are not a bad place to start.

I could not have been clearer in my post on 5/18 that I did in fact test fuse direction during my experiment. In the METHOD section, I said...

--Fuse direction was noted during every swap.

-- 3 auditions of each fuse in each direction

And in my RESULTS section, I said...

I could not hear any differences when changing direction for any of the fuses. Make of that what you will. Bad system. Bad ears. Bad method. Bad attitude. I just didn't hear it.

That should clear that up. As far as your comment that...

I have lost faith in ANY tests of fuses unless the person performing the tests is already familiar with the difference in sound fuse direction makes...

...you can't possibly mean what that appears to mean, namely that, in order to hear differences among fuses, you must have ALREADY HEARD differences among fuses. That would mean that no one could possibly hear differences among fuses FOR THE FIRST TIME. That is dumb.

You've been accused of many things, Geoff, but being dumb isn't one of them. So you must have meant something else.
