Anyone else using slugs instead of fuses? Comments on metals used and sound please

Thanks guys. I"ll call them to cut me a few

Replaced 4 components with silver  slugs.  Amp, pre, DAC, FOZ sound expander and all I can say is WOW!  Not minor.  Better than tube rolling or power cord upgrades.  Time to consider some additional protection options.  🤔

@lcherepkai, I don't like what you are doing. Love it. When listening to different fuses I briefly inserted a Cu. tube I cut to the correct size as a reference and thought I would find the fuse that sounded closest to it. I tried a bunch including Synergistic Research Blue, the most expensive, that I rated about middle of the group.  I decided to leave the Cu. slug in place. I could not go back to a fuse after this. 

The amp I used for experimentation is a DIY Neurochrome so I have no problem  modding it. After some time I decided to direct wire the input bypassing the cheap plated fuse holder by soldering in some 14AWG OCC Ag. This was an improvement again but now does not allow for swapping out different metals as you are so keen to hear your findings on Tungsten, Rhodium and also Cobalt should you ever get a chance to try.

The assumption being made here is that the different metals used in the fuse affect the sound in that particular function as a fuse.  But, have you considered the possibility that simply adding into the circuit these different metals might have the same effect?  Have you tried something like putting a second fuse holder in line with the one in the gear where different slugs can be inserted without compromising safety?

larryi:  I'm not much of a DIYer but I think you have a good idea.  May I send you a slug of a TBD material and you can try this for yourself?  I would be quite interested in your findings
