Fuses fuses fuses

good fuse-holders are generally copper alloy, silver plated in many cases, are available.

Non magnetic direct plating, in some. (no magnetic intermediary plating, ie nickel based)

Any recommendation?

Eaton and Littlefuse makes some beryllium copper silver plated fuseholders. Just a quick search away..at digikey, for example.

Acme Audio fuse holders, which I used to have back when I had fuses, are not only silver plated but cryo’d. Fuses should also be cryo’d for best results. Everything should be cryo’d. Almost all high end cable manufacturers routinely Cryo their cables. You have to if you want to compete in the marketplace.

Thanks

Please re-read my earlier post, "I think it is possible that exotic fuses sound different" (2017/070/09/6:15 PM).

Because I'm not making an assertion which goes against established physics. You are. The onus of proof is on you.
