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

Applies only to Synergistic. No idea what anyone else is doing, how or if they work at all.

Of course it does, the normal 6 pack of SR fusers, don't shill for other fuse companies.

Miller.
Interesting your comment on the motor controller.
I had forgotten I had tried an old SR Black I had lying around in a Walker motor controller.
At the time of installing I thought it had made some difference but I also upgraded the PC at same time. Turns out it was the PC making the difference, as I found by trial and error.
So basically zero effect on the Walker.
Also interesting you say biggest impact on your integrated as I would say that was smallest impact in my system.
But that is exactly what I am getting at in part with this thread.
How system synergy still applies even with fuse changes.
And we cannot ever rule out our own perceptions, expectation bias ( yes I acknowledge it exists!), room acoustics, phase of the moon etc etc.

It's part of what makes this whole game so much fun!

I have one simple request.
Can EVERYONE please ignore Aunty Fuse and anything it posts here.
Thanks.

Have only tried a Blue in my K&K Audio Trio and it was an improvement in transparency without any edge.

Replaced all the fuses in my SMc Audio amp with Hi-Fi Tuning but that was along with a major upgrade so can't be sure of any difference the fuses made. BTW, the board on this amp takes 7 fuses! The whole upgrade was super!

Preamp then amp.
