PADIS vs Furutech fuses


I now have about 260 hours on my PADIS fuse and ready to some listening. The PADIS fuse appears to look exactly like the Furutech fuse. It has the same blue casing with the PF logo on one side. Actually, the only visible difference between the PADIS and Furutech is that the Furutech has “FURUTECH” printed on the opposite side. However, there are actually differences:

My very initial thoughts on the PADIS fuse (in the first few hours) was that the PADIS seemed somewhat dryer sounding than the Furutech. The PADIS did not have the typical “cold / wet /chimey” tones that fresh rhodium plated Furutech components generally have (I’ve tested Furutech rhodium fuses, power cord connectors, interconnect – they all initially contribute this cold/chime character).

I have often stated that Furutech rhodium is painful to burn in. I have burned in many Furutech fuses and it goes through several painful areas. There are days in Furutech rhodium burn-in where I would sit down to listen and the sound would just be so bright / harsh / hard-edged that I said “I can’t listen to this”. At that point, I would just walk away and let it continue to burn in. With the PADIS fuses, it never got that painful. I could hear the burn-in process changes, but it was always listenable. At the 180-200 hour mark, the PADIS did get very bright/hard-edged, but it was still somewhat listenable (I did not have to walk away). At 220 hours it was fully resolved.

Now, for the comparison. I will say that the PADIS is an excellent fuse. For the money, you really cannot beat it, unless you need a warm signature (in which case you need an Isoclean fuse). Both the PADIS and Furutech share the same essential sonic signature. However, there is definitely a difference. The PADIS sounds very good – do not get me wrong, it is an excellent fuse. However, the Furutech really did have an improvement. The tones on the Furutech were just a bit more pure and true sounding. The Furutech had a more “solid” sound to the audio. The Furutech had a bit more punch and meatiness to the bass / midbass. The PADIS, on the other hand, was a bit more loose in the highs, causing the high frequencies to be a bit more messy and rattling. This does cause the PADIS to sound a bit more dry. The PADIS also did not have quite the depth of soundstage when compared to the Furutech.

Now some people might sit down with me and say “I can’t hear a difference” or “your just splitting hairs”. I might be. The difference in sound is VERY subtle, but to me it makes a significant improvement. The differences could also be revealed when listening over a longer period (like 20-30 minutes). The music with the Furutech is just more engaging.

If you have very low resolution or warm equipment, it is possible that you would not hear the difference at all. However, on high resolution stuff, the Furutech could make that equipment “shine” just a little bit better. The PADIS is an excellent buy. For half the cost, you get a whole heck of a lot of performance (almost a no-brainer if you’re still running a stock fuse!). For those who want to bleed out the most amount of performance and resolution – the Furutech is worth the cost.

There are a few possible reasons I can think of that would cause the PADIS/Furutech difference:

- Furutech fuse state a special damping filler inside to reduce electrical resonance. I cannot find an reference to a damping filler for the PADIS fuses.  This could be why the PADIS sounds a bit more loose/dry/harsh in the highs

- Furutech does a Cryogenic treatment process. I cannot find any reference that the PADIS fuses get the same treatement.

- Rhodium plating. It is possible that the Furutech fuses are manufactured with a much thicker rhodium plating. I know Furutech likes a thick rhodium plating on their A/C connectors. The PADIS could have put a thin plating on their generic “PADIS” fuses. This could help explain why my burn-in process was not as painful.

Anyways, those are my findings. Maybe next year I’ll do a BLUE vs. Furutech analysis.

How many of these guys can stand out on the ledge without the ledge breaking off?

Innocent question: if break in of cables is related to the dielectric materia, not the metal conductor, then why is break in for fuses necessary? You know, since there is no dielectric. Am I missing something? 

I’m pretty sure when someone is reduced to name calling and dropping names he’s completely run out of ammo. Besides I broke two of your sacred Laws of Science just today. No big deal. 
I hate to judge these things but did someone spike the punch in the adult day care ward? While we're on the subject, who dropped the ball on the Roach Motels this time? 

Anyone else think it’s ironic that the same naysayers who say blind tests would eliminate psychological biases like placebo effect and expectation bias from the equation, presumably to prove that the subject under test is a fraud, a ripoff, are the SAME dudes that claim that it’s all psychological? AND They’re the SAME dudes who never actually get down in the trenches and try these things. Sideline Sallys. AND they’re the SAME dudes who never test them. Coincidence? You decide. Real skeptics or fake skeptics?

Speaking of fleece here's yet another lost sheep following the wrong sheep. He could not hear high end fuses? That's a shame. Baaaa!

For those complaining that the difference measured for fuses was much too small to be significant, and that most volt ohm meters would be unable to actually measure the very small difference, you might consider measuring resistance of 100 feet of fuse wire. Then the difference in resistance would be what, a thousand times larger? Would it not be more obvious then that there’s something to this whole wire directionality thing? Anyone could measure that.

@geoffkait

You’re a liar and you have done no such thing.

Uh, calm down, Costco. Try to keep up with the discussion. This is like your ridiculous whining that no one had any measurements that you bellowed over and over again, even though the measurements were posted a great many times. I have described in detail the correlation of high end fuses to sound many times. You, know, like why there is a better signal because of better materials for the fuse wire, less vibration, resistance to RFI, etc. and there are a great many testimonies on these threads by customers describing the sonic changes due to aftermarket fuses, including the changes due to direction only. You have two ears and one mouth for a reason.


Costco, sorry but yer barking up the wrong tree. I never said any of those things. 
I shall not allow some charlatans and scoundrels to take advantage of young naive and gullible audiophiles. I shall not allow these pseudo scientists and tweakaphiles to besmirch and sully the good names of Ohm, Watt, Faraday, and the other Icons of Science and Electricity. Finally, I shall not allow any of the Laws of Science to be broken or otherwise injured. - The Naysayer creed

@geoffkait And what you fail to do is draw any plausible connection between what we know and the observed phenomenon.

>>>>I have drawn rain the connection to what we know and what we hear many times. You have failed to read it or have dismissed it or whatever.

People claim they hear things. Fine. WHY??? The attributes people describe are roughly in par with the characteristics of distortion. Cool. We can measure that. Why hasn’t anybody measured that?

>>>>>>How owe should I know?

Can it be measured? I suspect not.

>>>>>>Why assume anything? You’re just be argumentative.

Now if people want to buy fuses because they manipulate your brain into liking what you’re hearing, that’s kinda crazy to me, but I otherwise don’t care.

>>>>>Uh, I’m pretty sure it’s because The aftermarket fuses improve the sound. Id say you’ve managed to psych yourself out. Otherwise you don't care? Is that why you've wound yourself up into a froth?

. I’ve got a bunch of lights and lasers I use while listening because being visually distracted from the space enhances the listening experience. I guess you could say shining lights and lasers on my gear makes it sound better. The truth is that it’s all in my head though. That seems the most rational explanation for this question about fuses.

>>>>>As I said, it appears you’ve psyched yourself out. Good luck with all that.
I never said that the differences in resistance account for the differences in sound. What we have here, folks, is an excellent example of a Strawman argument. Even HiFI Tuning states that the small differences in resistance don’t account for the sonic differences, as I just quoted from their data sheets. The measured differences are, however, indicative of the directionality of fuses. All fuses. You know, because of the correlation of the differences to direction. Hel-loo!


Costco, If the measured differences were arbitrary and subject to a number of variables, as you say, the results would be random. But as I got through explaining, the results are not (rpt not) random. They’re consistent with fuse non symmetry, I.e., directionality. Ditto fuse body material, Cryo, etc. Follow? Your theory is as silly as the fuse holder explanation.
Reply to Mitch’s question, something to the effect, "where can I find the correlation of measurements to listening test?"

From the conclusions portion of the HiFi Tuning data sheets,

"The measurements done so far showed some measurable differences between fuse,
but didn ́t explain completely the sonic differences between fuses. One way to look at these phenomenon’s is, that music, containing many pulses can be limited by the electronics being in the reproduction chain. Fuses with better contact material (e.g. no corrosion) and overall better make will limit these pulses less."

If I may be so bold, what that first sentence intends to mean is measured results DO - at least partially - explain the listening results. In terms of not only directionality but fuse body material and fuse conductor material, including differences produced by Cryo treatment. In other words, the directionality of the fuses that was measured agrees with the listening tests. I suggest that the correct way to view the measurements is that they are indicative that the fuses are *non symmetrical*. No one is saying that the differences in resistance are the complete answer. But they are *evidence* that something is going on. Obviously if fuses were completely *symmetrical* the resistance would measure exactly the same both ways, no? 😳

While it’s true the measured differences are small, the differences are consistent. The resistance is consistently lower for audiophile fuses than for stock fuses; the resistance is consistently lower according to which end of the wire came out of the die first; cryo’d fuses have less resisitance than their non cryo’d counterparts. What the naysayers oft overlook is this: the measured results are consistent with listening results - the best sounding direction is the one with the lower resistance.

Expensive equipment? Oh, you mean like a $20 Radio Shack Volt Ohm meter? 😬

The question has been asked and answered scores of times. Do you think you're the only one? None so blind as those who will not see. 😎
Ba ba black sheep, have you any measurements? Yes, six bags full. Someone is following the wrong sheep.
