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.

"Good point Eldartford. Trying a fuse is just like risking your life on a tall building."

It is if you don't unplug it ;)
Of course Krell uses fuses. Go to their website and download the manuals like I did and read about the fuse specs like I did.
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.

"Not all amps have fuses...Krell for example."

That's crazy talk. Must have a fuse, no? I've never heard of such a thing. For nothing else so that your house doesn't burn down.
Sorry to beat the heck out of this Krell fuse thing.
Interesting about the KSA 250, it's the only one I saw that does not use fuses. I looked at 4 or 5 other manuals and they all spec'd the fuses.
Vhiner - You have been redeemed ;)

Talk about getting OT...

"Maybe you can provide a single documented event where ANY participant correctly picked the better “anything” 80% of the time?"

Can you provide a single documented event where the participants could not correctly pick the HI Fuse? Probably not.
You don't know they make no difference any more than the guy who sits and listens and trusts his ears and says they do.
IOW - You are both just guessing. But you are as sure as he is in what you believe, and you poke fun like you know something he doesn't.
Metro - Where anyone draws the line between superhuman and human is completely arbitrary.
Zip cord vs. expensive speaker cables superhuman?
NOS Tele vs. new production Electro Harmonix?
Budget amp vs. expensive amp?
mp3s vs. WAV?

You just happen to draw it beneath Hi Fi fuses (and brilliant pebbles in the other thread you started), some other guy draws the line somewhere else. My coworker was telling me the other day I was nuts because I said an iTunes-purchased album I copied to CD sounded bad, and I was wasting my money because I ordered the CD.

2 things I've learned in this hobby:
1. There is enough snake oil in Hi Fi to make your head spin
2. There is way more that goes into what we hear than we know in 2011. We are just scratching the surface.

My guess is that I would not hear a Hi Fi fuse in my system, and that probably nobody can in any system. It appears that it's your guess as well, but a guess it is.
FWIW - If it were me I would swap out the fuses with my eyes closed and see if I could REALLY tell, but not everyone's like me.

"There is a neat thread somewhere on this site that asks folks about their personal limits of acceptance for what is 'obvious' snake oil and what is worth consideration."

To me, this is the crux of the debate. When someone's limit is above or below their own some people simply cannot deal with that.
George Carlin had a bit like this about driving (apologies in advance for butchering):
When you come up on someone who is driving slower than you, you say, "C'mon A-hole, move it! That guy's an A-hole!!"
When someone passes you, you say, "Look at that mainiac! That guy's a maniac!!"
Dougmc - What you say does make sense, however there is always another point of view.
One way for this company to make it's upgrades seem more valuable would be to make other somewhat similar upgrades seem more valuable. IOW - They sell better resistors and capacitors, connectors, whatever. "Do they really make a difference?" the potential customer might ask himself. Well heck, even the fuse makes a difference, so the upgrades must make a difference also. "I'm gettin' them upgrades, Level 3 for me."
I don't know the company of course, so it's purely hypothetical. But I believe it's a valid point.
