Upgrading Fuses


Have a Audio Research Ref 3 and am considering upgrading the fuses but I am a little skeptical. Would like to hear from people who have try this. Hard to believe that fuses can make a substantial difference like the manufacturers claim. All advice appreciated.

Metro04,

You demanded measurements that explained Hifi Tuning's claims. It's been posted here. Why do you ignore the data and requests for your credentials? Because you continue to imply that they are snake oil salesmen, you owe the inventors at HiFi Tuning an apology. This isn't about you or me. It's about unqualified people like you slandering the good products of others, which you've never even tried or measured, by the way. If someone did this to something you made, you might begin to understand how wrong it is.

Apparently, I'm not the only member who is perplexed by someone who has contempt for a hobby choosing to post on a website dedicated to it.
Wow, Metro04 and Jeff_Jones,
If you want to read about and go crazy over some audiophile tweaks that will really turn you inside out check out the Coconut Audio products. They are way crazier in concept and believability than audiophile fuses. I can't wait to hear your reaction to these products.
Don't know, but it sure would be fun to see if they have any influence on the musicality of one's system. Just curious have you guys ever tried the tweak which I believe involves placing a nickel, dime, and a quarter (I think this is the right combo) on top of your speakers? Maybe someone knows the correct amount? I've heard this before and could of sworn it made a difference and cheap too!
