Should we upgrade high end fuses?

Why not? If you can spend hundreds and thousands on a high end power cord, I am sure a fuse would make significant improvements.

REMEMBER.....after your 20A dedicated lines, to your cryo'd outlets then to your gigantic power cords, the current ultimately passes thru a tiny fuse in your component. If the fuse would be of a good quality, it must make a difference.

I have Isoclean fuses throughout my system and YES, it makes a big difference. YMMV

I have (3) HIFI tuning fuses in my system and it did make a noticable postive improvement in the sound (cleaner and more detailed) but bypassing the fuse and fuse holder all togeather (going fuseless) provides far more sonic gain. When I removed the fuse from my cat JL2 amp, Jadis preamp and a fuse on my dynavector phono headamp the upgrade was far greater than simply changing fuses. The cheap fuse holder, usually about 85 cents retail on most audio units, really degrades the sound even when a upgraded high end audiophile fuse is added. It would be nice if somebody made a pure copper or bronze fuse holder to go with the expensive audio fuses currently on the market but to the best of my knowledge nobody does, what a shame as the fuse holder is the real choke hold.

I'm replacing my fuses with solid silver rods tomorrow. I'll get back to you on the improved sound.

Johnny (42659): Acme Audio Labs makes a silver plated, optionally cryo treated, fuse holder.

I know about the safety and all, but I picked up a length of 1/4" 101 OFC solid copper rod.
Fuses and their holders are definately weak links in any audio component.
I've been using the slug in my original Hydra since new, for 4 years, with no ill effects what so ever.
Now, don't nobody come jumping in on my butt about how wrong, unsafe or illegal this is,
I already know.
Folks have done this with Maggie speakers and other equipment as well for many years.
Anytime I do an interconnect or speaker cable change or move, system gets shut down and un-plugged from the wall to settle and cool.
Use at your own risk, if in any doubt, replace fuses with equal value and forget about bypassing entirely.
