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.

Actually for me the better way to determine rather than test equipment is to swap or not swap fuses and see if people can tell the difference. If test equipment doesn't show a change people will say it's not sensitive enough, etc. I would agree. Of course people will say they need time (hours or days), which may be valid unless they just said they heard a difference.
I was at a dealer's open house a while ago. He played some music and everyone liked it, oooh and aaaah. Then he showed us a CD mat that he put on top of the CD he just played. Much better...to everyone except me. I wasn't familiar with the system or the track he was playing, and I suspect others weren't either. I would have LOVED to do a blind test then. I would have been very impressed if others could tell the difference. Either way I would have learned a lot about my hearing, tweak's effectiveness, how people act in that environment, etc.
Thank God more people listen with their ears than with their test equipment. Even though the "fortune teller/magic/rip off" argument is in NO way applicable to what is going on here, it's helpful to consider that most secure people don't waste our time going on "fortune telling" websites trying to convince people who gather there that they are deluded. Yet some posters here are like all moral crusaders. They feel it is their moral duty rid the world of sin and protect us from ourselves. We leave them alone, but they can't leave us alone. We don't need their help and no one asked for it.

Again, this thread has been hijacked and it now belongs to those who claim to know THE TRUTH. Nothing I or anyone else says will keep them from taking over the conversation.
Just more of the same ol' classic evasion tactics regarding your unwillingness to support your touted claims, and it most certainly does equate to fotune teller antics in similar ways, or any other extrasensory claims humans having been making since speaking man, yet consistently fail when tested. You just can't differentiate betwen that either. And spare us the whole thread hijacking nonsense. It's not your thread or forum to regulate what suits your beliefs only. I've already addressed that point.

I swear, it's like I'm conversing with 5 year old. Your rational is predictable and sterotypical, without merit.
There are some things that you don't need to try.

I am selling anti-gravity boots. Put them on and you can jump off a tall building without falling. If you don't believe they work buy them and try them out. If they don't work I offer full refund.
