Upgrading Fuses

I agree that system resolution is definitely at play when it comes to system changes of any kind. I own Thiel CS3.7's (highly resolving) and use a ton of Shunyata power conditioning. Sometimes I can hear things I wish I couldn't. ;-0

My system is very resolving. I and another freind who has a very resolving system both agreed that if we could have listened first, we would have spent the money on music instead.
I'm not saying that they don't work, but in the two systems I heard, it wasn't that big of a tweek.

I can only attest to the use of Hifi Tuning Supreme fuses (not lesser iterations) sound in my DAC and transport. I will be installing one in my Classe' Delta 2200 amplifier over the weekend and others will be present to assess. If it fails to impress me, I have a paid return box and it will go back to Berlin.

I have little doubt that some designers of equipment have so dialed in their creations that changing fuses may fail to render an improvement or even harm the sound. Hifi tuning fuses can be found standard in some Lamm equipment and I'm sure they were selected from among many for a particular reason. System synergy could also be at work. Just as a 6922 tube is preferred by one person in one system but not in another system, it doesn't mean the 6922 doesn't work magic in some applications. FWIW.

BTW, spending money on music is always a good idea.

"The more resolving a system , the more likely a difference will be heard . "

This is one of the things that drives me crazy about audiophiles. Good design means resolving on the output side (where resolving is a good thing) and filtered on the power supply side (where filtering is a good thing).
A poorly designed system will have high resolution in regard to ac line effects & compromised resolution in regard to desired output. A well designed system will be the opposite. This is true whether you are talking stereo's or tv's or any other electrical device whose purpose is to transmit a signal. It is basic electronics 101 stuff. Good equipment has improved immunity to incoming power issues or tweaks.

Jeff,

If you're not an audiophile, why do you hang out here? This is an audiophile website. If we "drive you crazy", you might consider going to a website more pleasing to you. Or, perhaps you enjoy ridiculing people. I hope not. There are so few places left for hobbyists to enjoy what they do. You'll notice that I am not attacking the beliefs you hold, merely the spirit and manner in which you have chosen to express them here.
