Upgrading Fuses

I have a theory on fuse directionality...I installed the HiFi Supreme fuses in my pre and then source. Because of all the direction controversy I was compelled to test this myself on the pre(CJ CT-5) where its installation made a pronounced difference. Upon switching directions shortly after initial install (A>B>A), I wasn't convinced of a difference - but after about a week I noticed a slight edginess in the treble - and recalled that others have noted this with 'wrong' direction installs. Reversing the direction this time did make the difference.

So my opinion is that the fuse has no intrinsic preferred direction, but that the high voltage 'tunneling' effect is what causes the difference in sound. Tunneling effect is reasonably well accepted for interconnects/speaker cables, and the voltages here are certainly higher so effects may be even more pronounced? If others have noted audible differences, or determined they were installed in the wrong direction, only after some hours of initial use - this would support the tunneling theory. Any better ideas?

Sorry if someone else posed a similar thought - there are too many 'fuse' posts to read thru.

Noticed I used 'voltages' flagrantly. Although this is AC, the load, or draw, is presumably directional - So I should have said load.

I've tried it and it made a difference. It made my system more open, faster, articulate, tighter bass and more fluid treble. Listening to familiar music netted new details unheard before. I've tried it first on preamp and heard the change immediately. After that I changed the ones in the amplifiers. The difference became more obvious. Same presentation but more obvious to hear. I don't have golden ears but in my opinion a revealing system.

Changing fuse direction also changed the sound. This time it lost the openness and became darker. Bass became rounder, less detail overall but still better than stock (Bussman ceramic). I guess it depends on what the listener likes.

I just popped in two 5A slo blo HiFi Supremes in my old Acoustat tube servo amps.

The two 1/2 amp fast blos are on back order,but even with the job half done,the sound has improved.

Hard to describe to those who haven't experienced it,and when you try the best you can say is that things just improve in all areas.

Next up is my cd player,but it is costly,Nano fuse is tempting, but I've had such good sound with the Supremes I hate to use anything but them,if only for consistency.

When done that's 9 new fuses so that's about a $1000.00 investment in fuses.

I can hear the riddicule,but it doesn't faze me.

I've experience with other tweeks costing as much or more that haven't been as positive as the fuse upgrades.

And when it comes to swapping tubes or interconnects looking for the big improvement, most times they fail to live up to expectations,so you keep investing in those same tweeks, over and over.

To me a one time investment of $90.00 on a fuse doesn't seem foolish.

But for it not to appear foolish, you have to try it for yourself.

Lacee,

I know what you mean about more expensive upgrades not equaling the Supreme fuses....bought a $500 power cord once that didn't come close.
