Upgrading Fuses

Fantastic quote!

I only wished they had these Nano-Liquid fuses many years ago when I first got in this hobby !! These fuses are the REAL DEAL !...

First I want to thank Glenn for his generous offer on giving away a free HiFi Tuning fuse that I decided to grab for a couple of reasons.
I posted a few pages back that I had bought these fuses and almost heard a difference. Well, I realized that my system now is much more resolving than it was when I first bought the fuse a few years ago. That being said, I wanted to see if my newest system would show the HiFi fuses off.
I can safely say that there was quite a bit more clarity and lively-ness with the new fuse.
More energy throughout the band width. I was quite surprised at the results.
I wasn't expecting to here any improvement.
It wasn't as large as a power cord swap, but it was audible to myself and a close friend whom is also an audiophile.
I guess my system wasn't a resolving enough system at the time to hear a change.
But now? I'll be buying a new fuse for all of my components.
Again.... Thank you Glenn for extending a generous gift to a nay sayer and with an open mind, I have gotten a step forward in my system.

I've dad very positive results replacing the stock fuses in my ARC D-300 amp and Sonic Frontiers SFL-2 pre-amp with the ceramic body, gold-plated capped versions from HiFi Tuning--a German manufacturer. I can't explain the science, but since the fuse is the first thing your current passes through as it enters your equipment, upgrading does seem to improve the sound. It's not a revolutionary, knock-your-ears off improvement, obviously, but well worth the $30 or so each fuse costs--or so it seems to my ears. Call me nuts, but I even think the sound improves with time... Maybe fuses need to burn in just as cables do. One word of caution, however: Some manufacturers (ARC being one of them) advise against it because of questions about whether these imported fuses are up to UL-approved specs. When I queried an engineer at ARC about it, he conceded that they probably would improve the sound of my amp, but said the warranty would be voided if the fuse failed to protect the equipment. I know of no one who has had that problem and all the dealers I've dealt with highly recommend them. Still, it's use at your own risk (at least with ARC). Hope this helps.

The least expensive fuse upgrade is flipping all existing fuses in the system around - one fuse at a time - and listening to how the direction of each fuse affects the sound. Even for fuses that have been in the system a very long time. There's a 50 percent chance that a given fuse was originally inserted in the "right" direction.
