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?

No doubt it is possible to engineer a fuse that would retail at $1,000 but only millercarbon would buy them. I would be interested to know what is the maximum miller will pay for a wholly passive component; fuse or power cable. And the max he would recommend a very rich audiophile to pay, money no object.
And to be honest I am really not that interested in that at all.
Thanks and stay safe.
To those with SMc Audio gear, Steve and Patrick seem to have done extensive fuse auditions during their equipment burn-in processes and do provide different recommendations for different gear and even recommendations to shade the presentation differently for the sonic preferences of different clients.  They did indeed recommend Furutech fuses when they built my preamp some years ago but I just received my amplifiers back from them early this year and at that time they offered me the choice between either SR Blue or Orange fuses.
To my ears, the biggest improvement I’ve heard on my source components...streamer and CD players. The preamp and amp fuse swap resulted in very subtle improvement.

I have tested Furutech, SR Black, Hi-Fi Supreme Supreme Au/Ag and Cu. I end up preferring the HiFi Tuning Supreme Cu‘s in digital components as they slightly pushed the sound towards organic and warmer presentation.
I have never heard of using a fuse?  Aren't there fuses built in to each component?  How could a fuse cause any audible difference.  Maybe it is like the Emperors New Cloths?

Sorry Larry but I have to ask, where have you been over the last few years?
Aftermarket fuses have been one of the most contentious topics in these forums with some quite spectacular histrionics on display.
