Are reviewers who measure speakers smarter than the designers?

I do. :hey:
Many of those magic fuses ​can't meet basic certification. That means, when the time comes for them to perform that actual electrical function of a "fuse", they won't! That will certainly make a difference in the sound coming from the system.
Cute. I think Roger Modjeski discussed this many years ago after he had a couple of his amps come in (for service) fried because of this.

But you know what I mean, and I’m still curious to hear about a designer of electronics who would recommend an “audiophile” fuse.
 
You keep changing the story and I think you meant to say distortions above 40 kHz not 40 Hz. The fact is that JA said the Nyquist has low frequency distortion and high frequency distortion. It’s also noisy. I provided the link to the measurements so people can read what JA said and not your distorted version.

Yes indeed, thank you for the correction. DSD encoding creates distortion above 40 kHz.

Can you name one product designer (engineer) who believes "audiophile" fuses make a difference? Because there are any number who have stated they make no difference (of my equipment, Nelson Pass and Dan Wright).

I believe JC does , there are others , like PSAudio , Paul McGowan. Best fuse is no fuse , same for protection circuits , the best way for Amplifiers is to make PSU and output stages balanced to prevent driver failure , Low voltage stages would have fuse protection or relays.

In the same way Power cords type and not going straight to wall outlet affects sonics , its the same for fuses.

No.
But i can tell you my Lyngdorf´s, in the power zone, comes with ceramic fuses from Bussman. Not the basic ones in glass. But i think that does not prove anything.
And this is not (only) about fuses. Forget the fuses because I do not intend to start a discussion about fuses. My point is about a parallel industry of accessories that designers seem to ignore (not all of them, not all the time). Let´s keep talking about decoupling devices. For a long time ago there are a lot of solutions in the market. If they really work, why does some gear come with the most basic (plastic) feet? It would be better if we can easily remove and replace them, as we can do with power cables. But it´s good to see that some things are changing. See the examples of Nagra or Ayon.

Well, this is a good question, perhaps the question that deserves to be made. This question has twisted my mind since I started fuse rolling about 4 years ago. I hope (and I pray) :hide: that audiophile fuses are calibrated. I hope and I pray because I just can´t live without them! :cool:

Well, award from TAS and Hi-fi+ and DAC reference at Stereo vs. a bit of meh from Stereophile? Makes it 3:1.

Here’s a link to what Robert Harley has to say:

Why don't you just quit constantly defending your purchase if you think it was a wise one and just enjoy it. Where as you may think your purchase choice was the best available not everyone is going to agree and that is why there are hundreds of equipment manufacturers.
 
PS Audio may not be using Audiophile fuses costing in 100s but they clearly stated their fuse is not one of those cheap 5c chinese fuse. They use a decent one. Another example is AMR (who actually also sells fuse but they are cheap) also uses quality fuses in their equipment.

yes, best fuse is no fuse (just like best preamp is no-preamp :P) but you can't sell products in the US (and hopefully in many other countries) without one :rolleyes:
 
Would tend to agree with that, this is of course given the measurements are meaningful.

If there are e.g. distortions above 40 kHz as in DSD I am not sure whether I care, as I do not have ultrasonic hearing.

Why would one and in good conscience try to measure distortion above 40KHz ? would a reviewer be that dumb ?

Maybe not reviewers, but some manufacturers certainly do.

Magico and Raidho tweeters being specified to reach 50 kHz and above. Amps like Soulution claim to have a frequency range up to 100 kHz.

For manufactures/designers, yes, it makes sense. For them, the measurements tells a lot more than what humans can conceive.

Thread topic is one reviewer challenging the meaningfulness of some measurements audio reviewers are taking.

Background may or may not be that you can see Maggie 0.7s in the background. When those were reviewed in Stereophile the reviewer at that time thought they were excellent and recommended an A rating. But JA criticized them because of some of his measures and used his editor powers to grade them down. This is fairly easy within one magazine, cujus regio ejus religio.

So I posted an example where I thought I had observed something similar. While it is true that I am more likely to post about Magico, Pass or Shunyata and other products that I do have in my systems, I think that would be the same for most other Sharks as well. That is only natural as people usually know products better they have researched prior to purchase.

In this case a challenge was rightfully raised against my example, pointing out that there is a possibility the product in question has some challenges, because some measurements were taken and used to criticize it. To elaborate on why I thought this might be something like what Guttenberg was referring to, I shared three reviews and awards that product had received. Point being, if four similarly qualified reviewers assess the same product and 75% say it is superb and even give it a Product of the Year award and 25% say it is meh, purely stochastically seen the odds that one gets it right and three get it wrong is fairly low. Which kind of brings us back to the question how meaningful some of the reviewer measurements really are.

Two more measurement examples:
1) Tubes are bad and terrible, because they introduce some distortions to the system. Nevertheless some of the most experienced audiophiles swear on tubes and are convinced they simply sound the best. But there are ‘bad’ measurements. So what, tubes do sound good.
2) Harbeth vs Magico: some say Harbeths are terrible because the cabinet rings like a church bell. Others say they have been designed to have a resonating corpus, just like instruments. Truth is in the ears of the beholder.

Long story short, I absolutely think it is very important to measure in order to make good audio products. Whether reviewers always pick the relevant measures when reviewing them, I’m not so sure.
