Spec'ing the Ultimate "Hard Ball" Crack

[adydula]

Please give us a link or source for these "new" fuses...inquiring minds want to know!!

I would do something like this:
HiFi-Tuning Supreme

Can someone confirm the fuse specs? Is it as I posted earlier?

[Tom-s]

Slow or fast blow are both fine.

Originally the Crack comes with a 1A fuse.

(Edit: That's a lot of money for a fuse?! 60$?)

(Edit 2: and they are cryogenically treated, not cytogenetically, PJ's post)

[Surge]

Right- spelling autocorrect, then I was trying to be funny.

Indeed $50 is a lot for a fuse. But most users swear by them. I did the upgrade on my more expensive main gear, it's easier to justify on ~$5k gear.
I will order one for the Crack. Worth a try.

They grow and adapt to the current and blow based on biometric factors.


Yes, it's an evolutionary dead end

I have some "special" fuses from another project. 1A T (slow blow), what about the voltage? I assume 250V is fine?

[Tom-s]

Yes.

[Surge]

Thanks. I dropped in a Hifi-Tuning 1A slow. Btw, my kit came with a 1.25A F fuse...guess it doesnt matter.

I'm using this Hifi Tuning Supreme:

Haven't really done a proper back to back test; but it does seem a touch more transparent!

These fuses go on sale at Cable Co., and other places. I think I paid about $25.

The Hifi Tuning Classic fuses are on sale for $10:

[Tom-s]

That is, for all the values we don't need .

[Surge]

Oops, you're right; I didn't check. They go on sale often thought, because no one really pays $50+ for a fuse 
If you read the reviews, there does seem to be some real logic for why they improve the sound.

[Tom-s]

In my current location the wall sockets aren't grounded at all and i don't hear much of a difference... so.. meh.

I am no expert, but from what I've read, the issue is that the material used in fuses is the weak link in any system. It can create sonic resonance and other undesirable artifacts.
So it's not about the ground, but the fuse, and finding the best material to provide protection without deteriorating the sound.

Resonances are easy to measure. Vacuum tubes and fuses are made with very similar materials.

Beware o'the snake oil.

Crappy fuse material that conducts badly and thus affects the sound I can grok (not that I would pay $50 for a fuse). But I would appreciate an analysis of how the fuse's "sonic" (presumably this means acoustical/mechanical) resonance is energized, an analysis of the amount of energy we are talking about, and how that energy is transferred to the audio.

I'm thinking primarily of the mass of the fuse, and how much vibrational energy it could possibly transfer into the mass of the amp. I suspect you would need a meter with Diddly and Diddly Squat ranges, and it would fall somewhere in between. Presumably these acoustically superior fuses are composed of a sophisticated mass distribution to null out modes. I'd like to see that too.

Maybe they are just made of a lead bearing alloy, i.e. solder.
