Kinda hard to spend time and money on a fuse, although I guess at $50 each it might actually be worth it.

PS Audio with their early 200 watt amps came out with gold plated rail fuse holders and gold plated fuse caps. The power supply caps were joined by actual 3/16 thick copper buss bars !

As an aside I've seen some pretty nice stuff coming out for automotive stereo, so you may scour the net for car audio parts...

Interestingly certain standard manufacture fuses do sound better than what you normally find at RS and other cheap supply houses.

#1 American made fuses do sound better than the cheaper Chinese cr#p.

#2 For fast blow fuses there is a model that has what looks like a lightning bolt inside for the fusible element. I find them occasionally on Ebay if I have the time to carefully examine the pictures. More dynamic and quite a nice sense of slam and punch to them

I believe they still make them but they are more expensive (Digikey wanted $5 each ), hence most electronic stores do not sell them (somehow Buss comes to mind)

#3 For slow blo fuses, without spending a ton, the spring loaded MDL series are the ticket (they are labeled MDL/MDX. BTW). They employ a thicker fusible element but the spring adds tension to break the link at the proper rating: Again thicker element means more dynamics. Just checked Ebay and there's a bunch for sale, of course you need the value for your gear....

Most slo blo fuses employ that spiral winding of very thin wire. Several strikes against the design: inductive by design and the continued flexing of the element will cause it to prematurely fail. Watch the element as you turn on gear the spiral winding literally stretches and then contracts, stressing the metal tremendously.

The MD fuses I recommend are spring loaded ( and a quite a hefty spring at that)at one end and then tapers down to the fusible element.

They are expensive to manufacture as they have many more pieces. Military like them a lot, so check out surplus depots
