Where has been your most effective placement for an aftermarket fuse?


Not looking for a debate with anybody on whether aftermarket fuses work or not, this thread is for those fortunate members with the hearing to know that they do indeed work.
I am very interested in your thoughts and opinions as to where they work the best, the biggest bang for your buck if you like.
For myself I am going to say it is in my Metrum Onyx DAC.
And not just my present DAC, all of my last 3 DAC,s showed a very nice easily audible improvement with an aftermarket fuse.
Next I would say is in my Gold Note phono stage and lastly in my BAT integrated amp.

So what or where would you say has been the most noticeable piece of equipment that has benefited from a fuse change in your system?

I suspect Testpilot response was a joke which is fine, much preferred to vitriol!
However if serious I am truly interested in what he tried a fuse in.
uber,

That's good!  Maybe if the usual shillers, obfuscators (chief one is missing in action which bodes well for this) and other hardliners on both sides can tone it down a bit some useful information will come of it.
Exactly my fervent hope Mapman.

I thought a thinking man's fuse thread was long overdue.
I can but try.....
Also given the very proper assertion that results reported will vary case by case for many possible reasons (from no noticeable difference to whatever level of awesomeness is reported), it is not permitted to reject any reported results that displeases others or accuse people of bad hearing and/or bad systems, without any other evidence, as has pretty much always been done in threads past.

In other words....stick to the facts as presented.......

Here we go.....may the Gods have mercy on us......

To start, I have nothing new to report or assert that I have not already in the past. I tried a Red fuse given to me to try by another Agoner in my Audio Research sp16 pre-amp and heard no concrete difference between that and the stock fuse from ARC. It is sitting out as a spare currently.
I'm not a naysayer and am curious about aftermarket fuses.What stops me from trying them not knowing what is actually in them and will they protect the equipment same as the 50 cent fuses.Paranoia:-)
