Hello Hifial.
I confess I have changed fuses in my Metrum DAC, Lamm pre, and McIntosh amp and, like you, can barely hear differences. I can, but they are subtle. I tried HiFi Tunning fuses and now have SR Quantum fuses there...
But wanted to ask you about the fuse change you had done to your amps: did you replace the internal fuses as well as the "external" fuse (the one we can generally replace without opening the amp)? And what kind of amp do you have?
Mine is a McIntosh MC275, so tubes, and I only replaced the "external" fuse. So you have me wondering.
FWIW, I installed Bybee's Small Slipstream Purifiers (his cheapest) on the RCA inputs to my amp and they made a way more significant improvement than fuses - and they aren't exposed to blowing up, like fuses are :-)
